I have Siemens H CPU 414-5H in that I have used CP443-1 (6GK7 443-1EX30-0XE0, V3.0) for TCP/IP Modbus communication with Client DCS.

In this configuration I have used MB_REDSV block for redundant modbus comunication. As per manual for CP 443-1 I have make 4 way connection for redundant comunication and write program accordingly.

 After download all software and hardware when I check in client DCS for incoming date from our CP443-1, I can all data from all ports expecpt port 502.

Can I have any reasons why it is not communicating with port 502.

Thanks in advance for your feedback and support

Hi,

I have checked for other ports 503,504,501.

In all the above port communication done perfectly.

Only problem is on port 502.

Hope now you can better understand my actual problem.

Thank you.
