现用CP441-2做MODBUS 从站,驱动已安装,狗也装好了
调用FB180,运行时,FAULT慢闪(看资料:Interface is initialized and
ready, but nocommunication possible via S7-400 backplane bus.)
然后监控FB180中的ERROR_NR(故障号)为2,故障信息(ERROR_INFO)为1,查资料:Timeout when initializing CP or error when initializing CP(Error in BSEND job). 提供的指示:(Check if protocol “MODBUS
Slave” has had parameters assigned on this interface. Check whether the “ID” specified on the communications FB is correct.
Analyze ERROR_INFO.)
我根据例子ID=16#1000;而且我把例子里的块都考过来了,OB100和OB101里的中间点也按照例子改过来了
但FAULT慢闪没法解决,请各位老师给点提示,不胜感谢!
