DPV1命令說(shuō)明11.3.1概述背板CPU可以通過(guò)掃描儀向從機發(fā)送DPV1命令。為此，背板CPU向SST-PB3-CLX-RLL發(fā)出CIP通用消息。對象0x101，使用實(shí)例1。
要處理DPV1命令，應使用背板CPU初始化掃描儀DPV1\u INIT命令（必須處于脫機配置模式才能接受此命令）。當掃描儀聯(lián)機時(shí)，初始化后可以發(fā)送DPV1 Class 1命令。
IC698PSA100燃機模塊要設置DPV1 Class 2通信，背板CPU應發(fā)送啟動(dòng)命令。掃描儀自動(dòng)維護Class 2通信，直到出現網(wǎng)絡(luò )錯誤。
背板CPU應通過(guò)Abort命令關(guān)閉類(lèi)通信。CPU可以如果需要，使用Initiate命令重新啟動(dòng)Class2通信。
當不再需要DPV1通信時(shí)，背板CPU應停止DPV1模塊通過(guò)DPV1 Close命令。

DPV1 Command Description
11.3.1 Overview
The backplane CPU can send DPV1 commands to slaves through the scanner. To do this,
the backplane CPU issues CIP generic messages to the SST-PB3-CLX-RLL. Object 0x101,
Instance 1 is used.
To process a DPV1 command, the scanner should be initialized by the backplane CPU with
the DPV1_INIT Command (it must be in offline configured mode to accept this command).
DPV1 Class 1 commands can be sent after initialization when the scanner is online.
To set up a DPV1 Class 2 communication, the backplane CPU should send an Initiate command.
The scanner maintains Class 2 communication automatically, until a network error occurs.
The backplane CPU should close the class communication via an Abort command. The CPU can
restart the Class2 communication with an Initiate command if needed.
When DPV1 communication is no longer needed, the backplane CPU should stop the DPV1
module via a DPV1 Close command.
Note
The following arrays assume an alignment of 1 byte; make sure that the
ladder program's set parameters at the correct offsets.
