Venus OS开发者文档：GX设备的根用户访问与硬化指南说明书

Venus OS: Root Access1. IntroductionThis document explains how to access a GX device via SSH, or straight on the Serial Console, with the root user. It also covers customizing and hardening a GX device against nonauthorised access.This document is part of the Venus OS developer documentation. The main document is the Venus OS wiki on github.Do note that, while we try to maintain to provide all mentioned functionality in this document, the used commands and functionality may change with future updates.2. Warning about modifying the rootfs1. Your changes can be lost during a ﬁrmware updateChanges made to the rootfs will be lost in case of a ﬁrmware update. The complete rootfs is overwitten during an update.Of course it is always possible to disable automatic ﬁrmware updates. Also there is a data partition (/data), which will be left alone in the image updates, and as such can be used to, upon boot, (re-)install certain changes onto the active rootfs. More details on that below.2. It is possible to brick your GX deviceFor those unfamiliar with the term: Bricking means rendering it useless and unrecoverable. Chances of this are small (depending on what you do), but its certainly possible. And if not fully bricked, then at least in a state from which there is no documentation nor support on how to recover.Note that a solution to this is to do Venus OS experiments on a RaspberryPi rather than a real GX device. The advantage of a raspberrypi is that you can always start from scratch, by re-imaging the sdcard. And the other is that it (the pi) is a low cost device. more information on that.The factory reset procedure, as documented in the normal user manuals of the GX devices, removes everything from the data partition, except for the factory installed ﬁles. This will recover from issues caused by problems on the data partition, such as it being full or invalid settings or custom scripts.But it will not recover from all possible mistakes that can be made. Some examples:1.if you accidentally remove ﬁles crucial for the boot process, either on the boot partition or the rootfs, then the device won’t boot anymore. The above mentioned factory reset featuredepends on at least certain parts of the system booting up properly. More speciﬁcally, itdepends on the linux init process.2.if you remove the ﬁles in /data/venus, then -depending on the production date- you might have to restore those manually which might require serial console access. See below. Why does this depend on the production date? Thats because somewhere in 2021 we started writing allfactory data to a diﬀerent place (an eeprom) to make it more robust.3. Root access3.1 Set access level to SuperuserTo set the root password, ﬁrst set the access level to Superuser:1.Go to Settings, GeneralSet the Access Level to User and installer, the password is ZZZ2.3.Highlight Access Level (don't open the select page, ie. make sure you are in the General Page, not the Access Level page)4.Press and hold the right button of the center pad until you see the Access Level change toSuperuser. Note: when working from the Remote Console, you need to use the right key on your keyboard. Pressing and holding the right button with your mouse won't work.Now you have access to the super user features.Note that on a touchscreen, such as a Cerbo GX + GX Touch, there is no “right button”. Instead, drag the menu down and hold it down for ﬁve seconds. Or, use Remote Console.3.2 Create a temporary root passwordGo to Settings → General → Set root password. And create a temporary root password.Note that, for ﬁrmware version v2.00 and later, the root password will be reset by a ﬁrmware update. The reason is that the passwd ﬁle is on the rootfs, which is fully replaced by an update. More info here.Our advice is to create a complex root password. But use it to login only the ﬁrst time, and then install a public ssh key(s). Thereafter login with the keys. If key authentication works, you can also safely delete the root password afterwards (passwd –delete root).The password needs to be 6 characters long, minimum.3.3 Enable sshd and log inTo login via ssh, enable SSH on LAN (Settings → General). On Venus versions before v2.40, you need to enable Remote Support, which also enables sshd. More info on Remote Support here.To the login, enter the ip address of the GX device in a ssh client. Most Linux and Mac users will simply do this from the command line:***************.1.23And a very commonly used client for Windows is Putty. For more info, look around on the Internet, there is plenty information available.3.4 Installing ssh keysUsing a ssh key for authentication, instead of a root password, has the advantage that it isn't lost during a ﬁrmware update. The keys are stored on the /data partition.First set the root password (once), use that to login, and then copy a public ssh key to~/.ssh/authorized_keys.sshd works with three authorized keys ﬁles:~/.ssh/authorized_keys ← you can use this freely~/.ssh/authorized_keys2/usr/share/support-keys/authorized_keysThe third ﬁle contains the keys we use for Remote Support login.3.5 Play time! Start executing commandshttps:///live/open_source:ccgx:commandline4. Customizing a GX device4.1 Hooks to install/run own code at bootEverything, except for information on /data, will be wiped after an update.Therefore, the trick to make changes & modiﬁcations survive an update, is to put your (patch)ﬁles on /data, make them be (re-)installed automatically on startup.If the ﬁles /data/rcS.local or /data/rc.local exists, they will be called early (rcS) and late (rc) during startup. These scripts will survive upgrades and can be used by customers to start their own custom software. Implementation details in this commit.Also if venus-data.{tar.gz,tgz,zip} is found on removable storage (usb stick, sd-card) when booting, it will be unpacked into /data. Implementation details in this commit. Added per Venusv2.30~28. Use this to for example make a USB stick that installs the modiﬁcations.That venus-data ﬁle has one extra feature: if the archive contains rc/* ﬁles, it will extract those ﬁrst. And if there is a ﬁle called rc/pre-hook.sh it will run this before unpacking the rest of the archive. Similarly, if there is a ﬁle called rc/post-hook.sh, then that ﬁle will run this after the unpacking of the archive. For details, read the code in the /etc/rc5.d/S30update-data.sh ﬁle.You can test the 'update' with /opt/victronenergy/swupdate-scripts/check-updates.sh -update -force which will install the same version again, but in the other rootfs.For details of the used update mechanism, see here:https:///victronenergy/venus/wiki/swupdate-project4.2 Partitions, read-only rootfs and available disk spaceOn a GX Device, there are three partitions that matter:rootfs partition onerootfs partition twothe data partition4.2.1 One active rootfs at a timeOnly one of the two rootfs partitions will be in use at time. During a ﬁrmware update, the newﬁrmware is installed on the other one; and once ﬁnished the subsequent reboot will reboot the device onto that other partition.The data partition is not touched during a ﬁrmware update, except maybe some migration scripts that run at boot.4.2.2 Read-only rootfsBy default, the rootfs is mounted read only. Also, by default, it only has 5% of free space.The solution is to run /opt/victronenergy/swupdate-scripts/resize2fs.sh.Further details in the next section.4.2.3 Always prevent running out of diskspaceWhen doing modiﬁcations, make sure both the data partition and the rootfs do not run out of space. We don't design or test for that situation.With regards to the size of the data partition, thats easy to check using the df utility. But not so for the rootfs:After logging into a GX device, and checking the free disk space on the rootfs (! that is not the data partition), you might get a bit disappointed at ﬁrst. Don't worry about that, there will always be only 5% of free space, but thats not the actual free space:The reason for this is that a ﬁrmware update replaces the full ﬁlesystem on the rootfs, as an image. And its then not by default expanded to the full available space of the partition.To expand it, run /opt/victronenergy/swupdate-scripts/resize2fs.sh. It will expand the ﬁlesystem to use all of the available space.Also this remounts that rootfs as read-write.For actual available diskspace on our GX Devices, seehttps:///victronenergy/venus/wiki/machines.To see what resize2fs.sh is doing, without having to log into your Venus OS, see it also here. Note that a ﬁrmware update will replace all of the rootfs, as also explained above. Which implies that you'll need to run resize2fs.sh again after doing a ﬁrmware update.4.3 Creating a patch ﬁleAs mentioned before, the recommended way of customising Venus OS is by applying patch ﬁles. This section describes how to make and apply a patch.You start by making a copy of the original ﬁle and modifying it to accommodate your changes. In order to create a patch ﬁle containing the changes you’ve made, run the following command:diff -u OriginalFile UpdatedFile > PatchFileIn order to patch the original ﬁle with your changes, you can use the below command:patch OriginalFile < PatchFileFor more advanced features please check the manual page of diﬀ and patch.4.4 Adding or modifying servicesChanges made to /service will not survive a reboot. The reason is the/etc/rcS.d/S10overlays.sh script, which copies over the ﬁles from/opt/victronenergy/service/* to /run/overlay/service and bind mounts that under/service. So in order to have changes survive a reboot, you need to change the service under/opt/victronenergy/service/* instead of under /service.By default the root ﬁlesystem of Venus is read-only. There are three ways to change that: temporally: issue the command mount -o remount,rw / (which holds until the next reboot or issueing mount -o remount,ro /)semi-permanent: issue the command /opt/victronenergy/swupdate-scripts/remount-rw.sh (which holds until the next ﬁrmware update)permanent: adding one of the above commands to /data/rc.local (which holdspermanently)5. Hardening a GX device5.1 Limit physical access to the deviceThe ﬁrst thing to keep in mind is that we as Victron Energy always want an end-user with physical access to the device to be able to gain access to the device again after he has himself accidentally locked out.So the best solution to keep people from tampering with a Venus device is to block physical access tothe device. We do not give speciﬁc recommendations regarding that, but a compact server rack with key protection seems to be safe enough in most cases. You can also add an alarm on the digital input of the Cerbo that will ring as soon as the door of the rack opens.People with enough time, knowledge and for example an angle grinder on their hands will always be able to get in. But you will probably be able to tell if people did get access to the device. Also keep in mind that extra physical security will also give extra hassle for the people that are allowed to get the physical access to the device.5.2 Disable touch on the attached screenPer Venus OS version v3.00, we are introducing a feature that allows disabling the touch feature on the GX Touch display.This allows mounting the GX Touch where it is visible by the operators of the system; and at the same time prevent them from using that to elevate their access.Details per GX device:Ekrano GX: a digital input can be conﬁgured to be used for this. Wire it to a momentary-push button, that shorts the input (grounds it).Cerbo GX + GX touch: a digital input can be conﬁgured to be used for this. Wire it to amomentary-push button, that shorts the input (grounds it).Venus GX: has no screen, not relevant.Color Control GX: will not get this feature.Inside Venus OS, this is handled by the setting /Settings/Gui/TouchEnabled undercom.victronenergy.settings. Which can be scripted with the dbus -y command. See Limiting digital access for an example on how to do that.Note that this setting only disables touch/mouse control. On the remote console you are still able to control the device with keyboard input. That is also true if you plugin an external USB keyboard. With the keyboard it is also possible to toggle the /Settings/Gui/TouchEnabled setting by pressing the Pause/Break key key. So if you need this feature to be switched on, make sure that the USB ports are not accessible.5.3 Limiting digital accessWhen securing the device, it is also advised to disable the Wi-Fi access point, bluetooth and other non-essential services on the device. The below list should be treated as a starting point and can be extended up on:Disable remote touch controlDisable bluetoothDisable Wi-Fi Access pointSet Access level to UserDisable LAN SSHDisable LAN remote console (VNC)Disable Modbus TCPDisable MQTT (via SSL, plaintext and VRM)If you have multiple devices to harden, here is an example of how to automate the process in a scriptable way. Note that we might change those commands, or names and locations of those settings. Therefore, make sure to be careful to check for example the exit code of such script, as well as visually conﬁrm that all works as expected:#!/bin/bashitems="Disable remote touchcontrol;com.victronenergy.settings;/Settings/Gui/TouchEnabled;0Disablebluetooth;com.victronenergy.settings;/Settings/Services/Bluetooth;0Disable Wi-FiAP;com.victronenergy.settings;/Settings/Services/AccessPoint;0Set access level toUser;com.victronenergy.settings;/Settings/System/AccessLevel;0Disable LAN ssh;com.victronenergy.settings;/Settings/System/SSHLocal;0Disable LAN Remote console(VNC);com.victronenergy.settings;/Settings/System/VncLocal;0Disable Modbus TCP;Settings/Services/Modbus;0Disable Modbus TCP (Plaintext);Settings/Services/MqttLocalInsecure;0Disable MQTT on LAN (SSL);Settings/Services/MqttLocal;0Disable MQTT on LAN (Plaintext);Settings/Services/MqttLocalInsecure;0Disable MQTT via VRM;Settings/Services/MqttVrm;0"IFS=''for item in ${items}doIFS=';' read -r description service path value <<< ${item}echo "# ${description}"dbus -y ${service} ${path} SetValue ${value}doneThere are a lot more settings that can be adjusted this way. Easiest is using dbus-spy to check which ones you ﬁnd interesting. Instead of disabling services, you might want to enable some things too. Just replace the 0 with a 1 to do that.5.4 Installing a tamper alarmBy using the digital input(s) of the GX device, you can set the digital inputs as “Burglar alarm”, which can be used to be alerted on tampering events.Depending on the need, you might want to switch to a silent alarm under General → Audible alarm (service: com.victronenergy.settings, path: /Settings/Alarm/Audible).You can decide whether the input should be treated as an alarm condition, whether the labels should be inverted, and whether the logical levels should be inverted.To swap the labels attached to the alarm, set Inverted to on.If a logical low input (0V) should be considered a positive condition, set Inverted alarm logic to on.5.5 Hardening multiple devicesIf you have a lot of Venus devices to modify, probably the easiest way is to start with using a per-device speciﬁc password for the remote console, which only you can can generate. Combining that with a substring from something like /opt/victronenergy/venus-eeprom/eeprom –show serial-number | sha256sum is a fairly secure start.Later replace that by something more strong and store it in your vault. Use the USB stick to put your public ssh keys on the GX device so you can gain remote access.6. Connecting on the serial consoleThe serial console oﬀers a straight connection from your computer. Not relying on TCP or anything else.Its an alternative to connecting to the commandline over ssh.Connecting to the serial console requires a USB interface, ie a USB to serial cable with proper pin-out. For example this one: https:///product/954.The serial consoles on all GX devices are conﬁgured to 115200 baud.6.1 Color Control GXAll GX Devices have a dedicated serial console, except for the CCGX. Therefor its documented on a separate page:CCGX Serial Console.6.2 Cerbo GXThe serial console is located on the CPU board, header JP201. GND is pin 1, RX and TX are pins 4 and 5. Here is a picture showing a ADA Fruit Serial Console cable connected to it.Make sure not to connect the red wire.6.3 Venus GXThe serial console is located on the base-board, and can be accessed through the slot between that board and the Ethernet connector on the beaglebone-board.White: TX of the Beaglebone - connect to RX on your cable Black: ground Green: RX of the Beaglebone - connect to TX on your cableMake sure not to connect the red wire.Here is a picture showing how, also using the adafruit serial console cable as referenced above:6.4 GX Card / NanopiThe GX Card is the PCBA inside the MultiPlus-II GX and EasySolar-II GX product ranges. This photo shows the card, when unmounted from these inverter/chargers.Maybe the pins are also accessible without dismantling it, maybe not. Note that all this is at your own risk, as everything on these pages is.The serial console is the pinheader on the right of the photo. In the photo, there is an Adafruit serial console cable connected.6.5 Octo GXThe serial console is located on the base-board, and can be accessed with the top-board unmounted.

西门子SIWAREX称重模块校秤方法

文档来源为:从网络收集整理.word版本可编辑.欢迎下载支持. 西门子SIWAREX称重模块校秤方法
针对近期很多朋友第一次使用SIWAREX称重模块，而且在开始校称的时候遇到一些小问题。

以下就以两种方式进行说明，看如何实现“瞬间”校称。

简单总结为三步走方法SIWATOOL U软件为例
第一步：写校准砝码的重量，50KG为例，两位小数点，按“发送”命令。

就是告诉SIWAREX 称重模块砝码的重量。

界面如下：
第二步:在空秤的时候，点击零点有效。

只需要轻轻按鼠标即可。

界面如下：
第三步：将砝码或实物放入秤上（需要用点力气），然后用鼠标点击“校准重量有效”即可。

界面如下
这台秤就校好了。

为了保存标定数据，点击接收（Receive）即可，等以后换CPU的时候用。

其实大部分时候不需要保存。

CPU坏的几率太低。

如果是通过WinccFlexible来校称的话，就更简单了。

在一个界面下，就可以实现。

以SIWAREX MS为例。

其他称重模块相同。

进入校称界面后：
第一步：写入标定砝码重量。

以100KG为例，默认两位小数点，然后按发送即可。

界面如下
第二步：只需要在空秤的时候，用鼠标轻轻点击“零点有效”Zero valid即可。

界面如下
第三步：将砝码放到秤上，用鼠标轻轻点击“重量1有效”Weight 1 valid 即可。

界面如下
至此，这台秤标定完成。

如果有十几台秤，或更多，优势更加明显。

解决的时间更多。

When selecting the mode described below, the weight values refer to a fix reference point (as per pro-duction setting) and the zeroing at start up is disabled.Start-up with fix reference point: M35 12.4 Weight transmission with SiwatoolAfter successfully configuring the Siwarex and the weighing sensor, Siwatool can be used to weigh forcontrol purposes.The "Start Send" command (code 905) is used to send the individual records to the Siwarex. To con-firm, a record with “Receive” can be read out from the Siwarex. The communication can be stopped with the "Stop Send" command (code 906).Below in the picture, you can see the overview of the SIWATOOL:Figure 3: Siwatool(1) Control elements for SIWATOOL and the for the operation of the weighing sensor (2) Parameter list of the SIWATOOL module (3) Offline values of the SIWATOOL module(4) Online values of the connected SIWAREX module3Supported METTLER TOLEDO ProductsFTAV9.5.2WMS/WMSPBK9-APW/PBK9PFK9-APW/PFK9SLF6/SLF67Mettler-Toledo GmbH IndustrialCH-8606 Nänikon, SwitzerlandSubject to technical changes© 03/2017 Mettler-Toledo GmbHPrinted in Switzerland EN181_160407 4 Appendix4.1 Other Applicable Documents[1] METTLER TOLEDO, Reference Manual, Standard Interface Command Set (11781363G)[2] METTLER TOLEDO, Installation Manual PBK9 bench scales (30233012A)[3] METTLER TOLEDO, Installation Manual PFK9 floor scales (30233015A)[4]Siemens, Siwarex WP231, Device Manual, version 06/2014 (or later)4.2 FiguresFigure 1: Connection to Siwarex via RS485.................................. 3 Figure 2: Connection diagramm .................................................. 4 Figure 3: Siwatool (6)。

It can be used for automatic and non-automatic weighing, e.g. for the production of mixtures, filling, loading, monitoring and bagging.Purpose of this document for functional safetyThis programming manual contains important information that you will require to commission and use the device.It is aimed at persons who install the device mechanically, connect it electrically, parameterize and commission it, as well as at service and maintenance engineers.Notes on warrantyThe contents of this programming manual shall not become part of or modify any prior or existing agreement, commitment or legal relationship. All obligations on the part of Siemens AG are contained in the respective sales contract, which also contains the complete and solely applicable warranty conditions. Any statements on the device versions described in the programming manual do not create new warranties or modify the existing warranty.The content reflects the technical status at the time of printing. We reserve the right to make technical changes in the course of further development.Validation of this documentThis documentation is only valid in conjunction with the manual SIWAREX FTA.©Siemens AG 22 Organisation of the memoriesSince SIWAREX is working autonomous with a microprocessor, it has its own memory. A memory inside the PLC communicates with a memory of same structure inside SIWAREX module.All parameters of this memory are split into data records (DR). The data records are organised according to process steps (tasks) that you have to perform during the commissioning phase or during the process itself.Parameterisation of the SIWAREX module is done by writing data’s into its memory, Information’s about the process is done by reading data’s and order are given to SIWAREX by transferring specific data’s to the FTA.Data Record communication reduces the quantity of data's transferred to the minimum©Siemens AG 3©Siemens AG 43 Communication conceptThe next picture explains how the orders and the data’s are transferred to SIWAREX FTA.To read data’s, the user program gives a command code to the FB SIWA_FTA, the command for example “read data record 30” has a specific number in this case 230. Receiving this orderSIWAREX FTA sends the DR30 to FB-SIWA_FTA, who transfers the DR30 into the appropriate location of DB-Scale.To write data’s the user program write first those data’s into DB_Scale. Then, the user program gives a command code to the FB SIWA_FTA, the command for example “write data record 22” has a specific number in this case 422. FB SIWA_FTA read the DR22 from the appropriate location of DB-Scale and sends it to SIWAREX FTA.The next screenshot shows the contain of the STEP7 project.4 Giving an order to SIWAREX FTAFirst you need to know which commands exist. A list of all orders is to be found in the chapter 6 of the manual:A command is send thru defined data’s inside the data block DB_Scale.The function block FC Execute_Command. Manage a group of three commands, CMD1, CMD2 and CMD3. Those are foreseen to transfer orders to SIWAREX. CMD3 is used for OB35, CMD2 is used for the HMI panel and CMD1 is usually used by the STEP program. The three command blocks are to be found in the DB_Scale at address DBW40 toDBW50.The background task of OB35 refresh, every 100ms, the DR30, 31, 34, 35 and the ASCII weight with crypto data’s for legal for trade applications are also updated.©Siemens AG 5To send a command enter the command code at the address DBW40 as an integer.Then trigger the command by setting the bit s_CMD1.bo.CMD1_Trigger to “1” This bit has to be set with an edge to avoid double triggering of the command. The bit is automatically resetted to “0”.Bit s.CMD1.bo.InProgress indicates that the command is running, this can go for several OB1 cycles.Bit s.CMD1.bo.FinishedOK indicates that the command was successfully terminated.Bit s.CMD1.bo.FinishedError indicates for 1 cycle that the command was not completed. The code of the error is given in DB_Scale Byte 9 “b_CMD_Err_CODE”The number that is output is decoded in the table “Data and Operating Errors” in chapter 7.6.The value remains in the output until the next command is triggered. The evaluation is to be performed when the bit CMD_ERR:= “DB_SCALE”.bo_CMD_ERR is set.©Siemens AG 65 Reading and writing Data’sThe data records described in Chapter 5 of the manual and also in SIWATOOL (see PDF-File SIWAREX_FTA_Quick Guide_SIWATOOL) may be read or written.Always a complete Data Record can be transferred in one or another way.The order number to read a Data Record is “2xx” where xx is the DR-Number.For example read “Data Record 30” which contains weight and state of the scale is done with command “230”.Here an example of programming.The order number to write a Data Record to SIWAREX is “4xx” where xx is the DR-Number.For example to define the dosing setpoint you need to write first the value of the setpoint into DR20 this is address DB_Scale.DBD526. Then send the command “420” (Write DR20).DB72.DBX 31.4 is the trigger to write the setpoint coming from the S7 program.©Siemens AG7If you have any issues or suggestions regarding the related products or documents, please feel free to contact:Technical support for SIWAREX:Siemens AGIndustry Automation (IA)Sensors and CommunicationProcess InstrumentationD-76181 KarlsruheGermanyTel: +49 721 595 2811Fax: +49 721 595 2901E-mail: *******************************Website: /siwarex©Siemens AG8。
