Socket Relay (3)Chapter 1.IntroductionDOCA tools are a set of executables/scripts that are needed to produce inputs to some of the DOCA libraries and applications.All tools are installed with DOCA, as part of the doca-tools package, and can either be directly accessed from the terminal or can be found at /opt/mellanox/doca/tools. Refer to NVIDIA DOCA Installation Guide for Linux for more information.List of tools for both the host and the NVIDIA® BlueField® DPU:‣DPI compiler‣RXP compiler (rxpc)‣RXPBenchChapter 2.DOCA Tools2.1. Comm Channel Admin ToolCLI name: doca_comm_channel_admin_toolThe Comm Channel Admin Tool is used to monitor Comm Channel services and connections on both the DPU and the host.2.2. DPA HART Management ToolCLI name: dpahartmgmtThe DPA HART management tool allows users to manage the DPA's HARTs which are the basic resource of the DPA. The tool enables the resource control of HARTs to optimize the usage of computation resources of the DPA. Using this tool, users may query, create, and destroy HART partitions and groups, thus ensuring proper HART allocation between devices.2.3. DPACC CompilerCLI name: dpaccDPACC is a high-level compiler for the DPA processor. It compiles code targeted for the DPA processor into an executable and generates a DPA program.The DPA program is a host library with interfaces encapsulating the DPA executable. This DPA program can be linked with the host application to generate a host executable where the DPA code is invoked through the FlexIO runtime API.2.4. DPI CompilerCLI name: doca_dpi_compilerThis tool is used to create one of the necessary inputs to the DOCA DPI library.DOCA ToolsThe DPI compiler is used to compile a signature file which is loaded into the BlueField RegEx HW accelerator using a dedicated API (doca_dpi_load_signatures(cdo_file)). The output for the DPI compiler is a JSON-based CDO file.2.5. FlexIO BuildCLI name: build_flexio_deviceThe FlexIO Build tool is used to build and compile FlexIO device code into a static library. It is designed to generate a host library that encapsulating DPA execution. This tool relies on DPACC.2.6. RXP CompilerCLI name: rxpcThis tool is used to generate a ROF file that can be used by a customer application to program the NVIDIA® RXP® accelerator rules memories.The RXP compiler is used to compile RegExes into RXP Object Format (ROF) to be executed on the RXP accelerator.The DOCA RegEx library can be used to load the binary ROF file into the RXP.2.7. RXPBenchCLI name: rxpbenchRXPBench is a tool that allows performance comparison between the NVIDIA® RXP®hardware RegEx acceleration engine, found in the NVIDIA® BlueField® DPU, and the Intel®Hyperscan software library. It provides a comprehensive set of options and facilitates ingress of data from live network ports or previously recorded PCAP files.It is designed to provide a real-world comparison of these technologies and present the results customers could expect to receive after implementing either technology in their products.2.8. Socket RelayCLI name: doca_socket_relayDOCA Socket Relay allows Unix Domain Socket (AF_UNIX family) server applications to be offloaded to the DPU while communication between the two sides is proxied by DOCA Comm Channel.NoticeThis document is provided for information purposes only and shall not be regarded as a warranty of a certain functionality, condition, or quality of a product.

The twin input terminals allow for daisy-chaining of supply (max. 10A).A green LED on the front of the unit indicates that power is on, and a red LED illuminates during error conditions.In the event of a field wiring or barrier fault from any barrier on the Power Rail, the integral collective error messaging relay alerts the controller via a single digital I/O point. This relay can be configured as normally open or normally closed.Additionally, the bus implemented in the Power Rail isforwarded to the outside terminals 13 and 15 for usage with KFD2-WAC2-Ex1.D RS 485 connection. Terminal 14 is only for test purposes.In the sense of functional safety (SIL) the device provides no dangerous failures. Thereby the safe condition of the supplied barrier must be defined as the powerless state. Thus the device will not influence the safety calculation or the SIL value.This device is compatible with all versions of the Power Rail and provides group fusing.Note: Redundant systems require two KFD2-EB.R4A.B modules.FeaturesFront view16-05-23 12:04D a t e o f i s s u e 2016-05-23189784_e n g .x mlSupplyConnection terminals 11+, 12-terminals 8+, 9-Rated voltage U n20 ... 30 V DCThe maximum rated operating voltage of the devices plugged onto the Power Rail must not be exceeded.Power dissipation ≤ 2.4 WOutputSupply Output current: ≤ 4 A Fault signal relay output: NO contactContact loading30 V AC/ 2 A / cos φ ≥ 0.7 ; 40 V DC/ 2 A Energized/De-energized delay approx. 20 ms / approx. 20 msFuse rating5 Arecommended maximum utilization of the fuse: 80 %Directive conformity Electromagnetic compatibilityDirective 2014/30/EU EN 61326-1:2013 (industrial locations)ConformityElectromagnetic compatibility NE 21:2006Degree of protection IEC 60529:2001Ambient conditions Ambient temperature -20 ... 60 °C (-4 ... 140 °F)Mechanical specifications Degree of protection IP20Mass approx. 100 gDimensions 20 x 119 x 115 mm (0.8 x 4.7 x 4.5 in) , housing type B2Mountingon 35 mm DIN mounting rail acc. to EN 60715:2001Data for application in connection with Ex-areasStatement of conformityTÜV 00 ATEX 1618 X Group, category, type of protection, temperature class ¬ II 3G Ex nA nC IIC T4Directive conformityDirective 2014/34/EU EN 60079-0:2012+A11:2013 , EN 60079-15:2010International approvals FM approval Control drawing 116-0160Approved for Class I, Division 2, Groups A, B, C, D; Class I, Zone 2, IIC UL approvalApproved for Class I, Division 2, Groups A, B, C, D; Class I, Zone 2, IIC CSA approval Control drawing 116-0160Approved for Class I, Division 2, Groups A, B, C, D; Class I, Zone 2, IIC IECEx approval IECEx UL 16.0051Approved for Ex nA nC IIC T4 Gc General information Supplementary informationStatement of Conformity, Declaration of Conformity, Attestation of Conformity and instructions have to be observed where applicable.

The fuse-protected power feed module can supply up to 150individual devices depending on the power consumption of the devices. Collective error messages received from the Power Rail activate a galvanically-isolated mechanical contact.Power Rail UPR-03The Power Rail UPR-03 is a complete unit consisting of the electrical insert and an aluminium profile rail 35mm x 15mm. To make electrical contact, the devices are simply engaged.Profile Rail K-DUCT with Power RailThe profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables. Due to this assembly no additional cable guides are necessary.Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!Accessories。

4.1 Tool Book 概述
ToolBook 是一种面向对象的多媒体开发工
具，由美国Asymetrix公司推出。适用于创 作功能丰富的多媒体课件和多媒体读物。 ToolBook设计过程如同构造一本书。首先 建立一本书的整体框架，接着可在书中添 加页，再把文字、图像、按钮等对象放入 页中。 应用系统的建立主要通过使用程序设计语 言 OpenScript 来编写脚本，确定各种对象 在课件中的作用。

2. 处于读者层次时，可以执行或播出这个
多媒体节目，即可以让读者阅读这本书， 此时菜单条上只有五项菜单，也没有工 具箱。所以读者不能编辑这本书，只能 阅读。 开发者在作者层建立应用，在读者层测 试执行应用，最终用户在读者层执行应 用。

4.4 Tool Book 的程序设计
脚本语言： 通过使用ToolBook的 程 序 语 言 OpenScript 可以为每一个对象编 写脚本，由此来决定 应用程序怎样为对象 的特定消息作出反应。
