Its sole purpose is to describe the opti-onal EtherCA T ® field bus interface.It is assumed the reader is already familiar with the EtherCA T ® field bus. Vast information about Ether-CA T ® and the CANopen Protocol is available at the below references and in the documents listed below. All parameters follow the common EtherCA T ® communications profile IEC 61158-x-12, CiA 301 (CA-Nopen Application layer and communication profile) and CiA 408 (CANopen Device profile fluid power technology proportional valves and hydrostatic transmissions). 1.1 Further documentation for the digital valvesThis manual is part of the complete documentation for digital valves existing of the following documents: • ProPxD parameter description • User manual valve Software: • ProPXD• ParkerDFPEtherCA T.xmlVisit /euro_hcd to download.1.2 ReferencesBelow organisations provide information about standards for EtherCAT ®, CANopen and the deviceprofile used.MSG 11-5715-708 E therCA T U K N EU.indd 03.09.197Parker Hannifin CorporationInstallation ManualValves with EtherCAT InterfaceDocuments of importance are listed below.1.2.1 EtherCAT ® FeldbusThe EtherCAT ® field bus interface provides a 100 Base full duplex real time Ethernet connection to the digital valves using standard EtherCA T ® frames according to IEEE 802.3.1.2.2 Object dictionary (CANopen over EtherCAT ®)1.2.3 Device profile1.2.4 Initiator of EtherCAT ®EtherCA T ® is a registered trademark and patented technology, licensed by Beckhoff Automation GmbH, Germany. EtherCAT ® was developed in 2003 by Beckhoff Automation GmbH and propagated as an open standard. To further develop the technology, the user association “EtherCA T ® Technology Group” (ETG) was established.Beckhoff’s product TwinCA T ® was used to verify the functionality of the EtherCA T ® interface. 2. Scope EtherCAT ® interface• Diagnostics (actual value feedback, temperature, fault, voltage, time of operation) • EtherCA T ®-status LEDs (Link/Active) • Valve status LED• Reduced Device State Machine (DSM) as per device profile CiA DSP-408 • Bus-cycle time down to 0.250 ms• 2 x EtherCAT ® – Connector M12x1 / 4-pin, d-coded (female) • Maximum operating temperature 85 °C8MSG 11-5715-708 E therCA T U K N EU.indd 03.09.19Parker Hannifin CorporationInstallation ManualValves with EtherCAT Interface3 Ethernet connectionThe EtherCA T ® vales are equipped with two M12x1 socket 4-pin (female), d-coded connectors, one EtherCA T ® IN and one EtherCAT ® OUT to implement the common bus topologies.

Directly at the connector is the operation mode LED of the valve. On another PCB there are 3 LEDs for EtherCA T ®monitoring.10MSG 11-5715-708 E therCA T U K N EU.indd 03.09.19Parker Hannifin CorporationInstallation ManualValves with EtherCAT Interface5 Adding the device in TwinCATAny EtherCAT ® master should be able to communicate with the valve. The configuration is described for the TwinCA T ® System Manager from Beckhoff Automation GmbH. For offline configuration (applica-tion design), the slave configuration file ParkerHCDEtherCA TValves.xml should be available in the di-rectory C:\TwinCA T\Io\EtherCAT (TwinCA T ® 2) or C:\TwinCA T\3.1\Config\Io\EtherCAT (T winCAT ® 3). Online the devices can be scanned with the Scan Devices… menu command. The device has to be connected to the master. Select I/O Devices . Now press F5 or the magic wand button or the right mouse button and from the drop down Scan Devices …Follow the instructions of TwinCA T ® and when the devices are successfully configured, one should seesomething like the below:The valve can be operated by changing the values with the Set Value Dialog . Select tab Online , buttonWrite…These are the I/O’s to be connected to your control software. On how to accomplish this, see the T win-CA T® documentation or the documentation for your EtherCAT® master. The I/O’s are described by the objects 6040h , 6041h , 6300h , 6301h , 6380h and 6381h , see their descriptions further on.The device parameters are changed in the Set Value Dialog of the CoE-Online list. See below.6 WatchdogsThe EtherCA T® Slave Controllers (ESCs) support up to two internal watchdogs (WD), a Process Data watchdog used for monitoring process data accesses, and a Process Data Interface (PDI) watchdog monitoring Process Data Interface activity. They can be useful when implementing data intensive ap-plications.The timeout for both watchdogs can be configured individually, but they share a single Watchdog Divi-der (WD_DIV), register 0400h :0401h ). The watchdog timeout is calculated from the Watchdog Divider settings multiplied with the Watchdog Time settings for PDI (WD_PDI, register 0410h :0411h ) or Process Data (WD_PD, register 0420h :0421h ). Base time unit is 40 ns. The watchdog timeout jitters, the jitter depends on the Watchdog Divider settings. I.e., selecting smaller Watchdog Divider settings results in smaller jitter.The following equations are used for a quick estimation of the watchdog timeout (they are not exact in terms of nanoseconds):t WD_Div = (WD_DIV + 2) * 40 nst WD_PDI = [t WD_Div * WD_PDI ; t WD_Div * WD_PDI + t WD_Div ]t WD_PD = [t WD_Div * WD_PD ; t WD_Div * WD_PD + t WD_Div ]Registers used for watchdogs are described below.Timing for the watchdogs can be set in TwinCAT® as below. First select Box1 (Servo Valve DFplus), tab EtherCAT®, button Advanced Settings…The SyncManagers and other registers can be accessed in TwinCAT as below.6.1 Process Data WatchdogThe Process Data Watchdog is rewound (triggered) by a write access to a SyncManager buffer area, if the SyncManager is configured to generate a watchdog trigger signal (SyncManager Control register 0804h .6 for SyncManager 0, etc.). The watchdog trigger signal is generated after the buffer was com-pletely and successfully written (similar to the Interrupt Write of a SyncManager).The Process Data watchdog can be disabled by setting the Process Data Watchdog Time to 0.A timeout of the Process Data watchdog has the following consequences:• Watchdog Status register for Process Data (0440h .0) reflects the watchdog status.• The device is disabled (could be useful to implement user defined behaviour here).• The Watchdog Counter Process Data (0442h) is incremented.• A bus communication fault is generated.6.2 PDI WatchdogThe PDI watchdog is rewound (triggered) by any correct read or write access by the Process Data Interface. The PDI watchdog can be disabled by setting the PDI Watchdog Time to 0.A timeout of the PDI watchdog has the following consequences:• ESC DL Status register (0110h .1) reflects the watchdog status. This can be mapped to the ECA T interrupt to inform the EtherCAT® device.• The Watchdog Counter PDI (0443h) is incremented.7 CAN over EtherCAT® object dictionaryThe below is extensively described by the CAN in Automation (CiA®) e.V. in their documents CiA Draft Standard Proposal 301 (CANopen Application layer and communication profile) and CiA Draft Standard 408 (CANopen Device profile fluid power technology proportional valves and hydrostatic transmissions. Further the valve is equipped with an RS232 interface. Several parameters of this interface are mapped on EtherCAT® objects. For example U22, power supply voltage [1/10V] is mapped to object 2802h. U22 indicates that it is originally an RS232 parameter. See the ProPxD documentation for these RS232 parameters.8 Synchronisation manager (SM)Several synchronisation managers allow consistent and secure data exchange between the EtherCAT® master and the slave device. The SMs inform both sides about data exchange status.The SM settings in the object dictionary have read only access. These settings are read by the master at start up and are needed to configure the process data and mailbox communication.8.1 Object 1C00h: SM communication typeDetermines the direction and type of the communication for the specified SM channel.8.2 Object 1C12h: SM2 receive PDO assignment: SM3 transmit PDO assignment8.3 Object 1C13h9 Process data object (PDO) communicationThese objects define the parameters communicated over the real time communication channels of SM2 and SM3. The communication channels exist of 3 buffers so writing and reading can take place simul-taneous. Mailbox communication uses only one buffer so reading and writing takes place alternating.9.1 Process data object mapping (PDO mapping)The object 1600h represents the RxPDO mapping and the object 1A00h represents the TxPDO map-ping. Sub-index 00h contains the number of valid mapping entries within the mapping object. Sub-indeces 01h to 08h contain the references to the mapped application parameters. The application parameters are referenced by their index, sub-index and length. The length contains the length of the application parameter in bits. This may be used to verify the mapping.The pointer contains a combination of index, sub-index and length of the parameter to be used. It may only refer to parameters with a bit length of 10h.Remapping is not implemented. The objects are configured to be read only.9.2 Object 1600h: RxPDO mapping (CiA 301/408)The parameter no. of mapped application objects in PDO (1600h) sets the number of real-time appli-cation parameters to be received. The application parameters are mapped by combining its index, sub-index and length to a 32 bit number which is written to one of the index positions within the PDO object.The following three parameters from the object dictionary are mapped as process data parameters by default according to CiA 408:Device state machine (DSM) Control Word (6040h)Spool position setpoint value (6300h sub-index 01h)Pressure setpoint value (6380h sub-index 01h) (D*FP only)9.3 Object 1A00h: TxPDO mapping (CiA 301/408)The parameter Nr. of mapped application objects in PDO (1A00h) sets the number of real-time appli-cation parameters to be transmitted.

In doing so it provides an error history.Parameter U24, Error codes + operating counter, is mapped on this object. Only the last 10 errors + minute counter in the additional information field. Value Definition:• The object entry at sub-index 00h shall contain the number of actual errors that are recorded in thearray starting at sub-index 01h . Note: If no error is present the value of sub-index 00h is 00h and a read access to sub-index 01h is responded with an SDO abort message (abort code: 0800 0000h ). • Every new error is stored at sub-index 01h ; older errors are moved to the next higher sub-index. • Writing 00h to sub-index 00h deletes the entire error history (empties the array). Other values than00 h are not allowed and lead to an abort message (error code: 0609 0030h ). Don’t use this option when the valve is enabled as the EEPROM erase routine blocks the regulator interrupt and the valve does not operate properly for a second.• The error numbers are of type UINT32 and are composed of a 16-bit error code and a 16-bit addi-tional error information field, which is manufacturer-specific. The error code is contained in the lo-wer 2 bytes (LSB) and the additional information is included in the upper 2 bytes (MSB).Fehler Codes: siehe das unten beschriebene Objekt 2000hY2 Error codes.Value descriptionIf a specific error occurs, the corresponding error group bit is set to 1 b . The generic error shall be set at any error situation. The bits are cleared automatically when their corresponding errors have gone.13 Error codesThe device internal errors are mapped on the CiA 301 defined object 1001h . The correct error informa-tion is provided by (RS232) parameter Y2 mapped on object 2000h . Error handling and acknowledge is provided by parameter J12 mapped on object 2001h .

Each error code is valu-ed only once. Error bits, when not pending, can be reset by writing a 0 b to their location (don’t set a bit when the valve is enabled, this will disable the valve as if a real error occurred.Examples:Error code 0019h:overcurrent shutdown (code 0001h) + under voltage guard (code 0008h) + bus communication error (code 0010h)Error code 0028h:undervoltage guard (code 0008h) + SPI bus communication (code 0020h)13.4 Object 2001h: J12 Error handling/acknowledgeErrors, for which the corresponding bits are set in this object, are acknowledged automatically, when not pending.14.1.3 Object 2804h : J8 Supply voltage supervision [1/100 V]Used to set the under voltage limit in 1/100V .

Can be changed by writing a value. Shows together with object 280E h the operating time.14.1.9 Object 280E h: U21 Operating time minute counterTime in minutes the valve is operational and enabled. Can be changed by writing a value. Shows toge-ther with object 280D the operating time.15 Storing / restoring parametersThe electronics of the device provides a non-volatile memory which allows storing parameters. The current values of all parameters declared as non-volatile (persistence = Y) can be stored in non-volatile memory on the device. Three storing / restoring operations are possible:• Parameters can be stored in non-volatile memory• Parameters are loaded during a power on cycle• Factory settings can be restoredDuring power on the user parameters stored in non-volatile memory are loaded in volatile memory to be worked with. The user can change parameters to adjust the behaviour of the device. After a power cycle these changes are gone unless they are stored in non-volatile. When messed up the factory settings have to be restored.15.1 Object 1010h: L2 Store parameters (CiA 301)Storing is performed when the signature 65766173h (“save”) is written to the parameter. The parameters are stored in user memory and loaded as working parameters each power cycle.15.2 Object 1011h: L1 Restore default parameters (CiA 301)The factory settings can be restored by writing the signature 64616F6C h (“load”) to the parameter.。

常见问题及解决方案
派克软管接头密封形式讲解
软管接头的型式确定其实可以从外观、密封表面形式及螺纹形式来确定。
通过外观可以判断是直接头，还是弯接头等等，而各种接头的螺纹形式从外表看起来都比较类似，为正确分辨就需要用到螺距规或者卡尺等专业的测量工具。
今天，我们就针对密封形式来进行讲解，看如何先通过密封来确定接头的大概型式。
软管接头的密封形式：
螺纹
O型圈
配合角度或金属—金属连接
带O型圈及相关配合的角度
螺纹：外螺纹和内螺纹连接后其牙型之间的挤压可形成密封，典型的螺纹密封连接形式为锥螺纹密封。
O形圈：外螺纹接头上的O形圈挤压在相应的内螺纹配合面上形成了密封，在高压系统里通常采用这种密封型式。
配合角度或金属与金属硬密封：螺纹锁紧后，一定角度的金属斜面相互契合并紧密的挤压在一起产生形变后形成密封。
带O型圈的斜面：这种接头将金属斜面密封和O形圈密封两种方式结合在一起，当锁紧螺母时，密封面相互契合，并使O形圈在两者之间变形。
