DPV1命令说明11.3.1概述背板CPU可以通过扫描仪向从机发送DPV1命令。为此，背板CPU向SST-PB3-CLX-RLL发出CIP通用消息。对象0x101，使用实例1。
要处理DPV1命令，应使用背板CPU初始化扫描仪DPV1\u INIT命令（必须处于脱机配置模式才能接受此命令）。当扫描仪联机时，初始化后可以发送DPV1 Class 1命令。
IC698PSA100燃机模块要设置DPV1 Class 2通信，背板CPU应发送启动命令。扫描仪自动维护Class 2通信，直到出现网络错误。
背板CPU应通过Abort命令关闭类通信。CPU可以如果需要，使用Initiate命令重新启动Class2通信。
当不再需要DPV1通信时，背板CPU应停止DPV1模块通过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.
