KUKA KSD1-32伺服驱动,KSD1-32使用书
PROFIBUS主模块可以记录两个输入/输出故障设备丢失-只要在上检测到PROFIBUS故障，就会记录此故障配置的从机，例如超时。也就是说，每当设备在从设备中位时状态表从1转换为0，如果没有网络损耗。添加设备-只要设备位处于从属状态，就会记录此故障表从0过渡到1，表示设备在PROFIBUS中处于活动状态扫描列表。
KUKA KSD1-32伺服驱动下图显示了Machine Edition软件中的输入/输出故障表显示。通信请求功能（COMMREQ）允许程序通信带有GE Fanuc智能模块，如PROFIBUS主模块。COMMREQ函数使用包含待处理数据的命令块与其他设备通信，以及与执行COMMREQ。命令块必须使用数据移动指令，例如move或BLKMOV（块移动）。CPU在状态字中报告COMMREQ的结果，状态字是一个PLC数据存储器中的位置。状态字地址在命令块中指定。有关状态字中报告的状态代码列表，请参阅上的“COMMREQ状态字”第4-8页。有关PROFIBUS主模块支持的COMMREQ任务列表，请参阅第4-9页的“PROFIBUS主模块COMMREQ参考”。本讨论概述了COMMREQ指令。有关详细信息COMMREQ梯形图指令，请参阅随提供的联机帮助编程软件。这个通信请求开始于COMMREQ梯形图指令为激活。
There are two I/O Faults that can be logged by the PROFIBUS Master module
Loss of Device - This fault is logged whenever there is a PROFIBUS fault detected on
a configured slave, such as a timeout. That is, whenever the device bit in the Slave
Status Table transitions from 1 to 0, this fault will be logged if there is not a
LossOfNetwork.
Addition of Device - This fault is logged whenever the device bit in the Slave Status
Table transitions from 0 to 1, indicating that a device is active in the PROFIBUS
scanlist.
The following figure shows the I/O fault table display in the Machine Edition software.The Communication Request function (COMMREQ) allows the program to communicate
with a GE Fanuc intelligent module, such as a PROFIBUS Master module.
The COMMREQ function uses a command block that contains the data to be
communicated to the other device, plus information related to the execution of the
COMMREQ. The command block must be placed in the designated memory area using
data move instructions, such as MOVE or BLKMOV (Block Move).
The CPU reports the result of the COMMREQ in the status word, which is a single
location in PLC data memory. The status word address is specified in the command block.
For a list of status codes reported in the status word, see “COMMREQ Status Word” on
page 4-8.
For a list of COMMREQ tasks supported by the PROFIBUS Master module, see
“PROFIBUS Master Module COMMREQ Reference“ on page 4-9.This discussion provides an overview of
the COMMREQ instruction. For details
