Hello All,

I have a client that wants to connect the PLC 1500 module to an older communication system that uses Modbus TCPIP. Could anyone please help me figure out what blocks I need to add in the logic and what inputs and outputs I should use? Thank you in advance!

Best,

Hello learnee;

Have a look at these links, for starters, explaining how to program and configure the MB_CLIENT and MB_SERVER blocks:

• A sample program from our friend Denilson Pegaia:

Sample Program: Modbus TCP with S7-1500

https://support.industry.siemens.com/tf/ww/en/posts/98690/

• And one of many FAQs on the subject:

How do you program and parameterize Modbus/TCP communication between two S7-1500 CPUs?

Hope this helps,

New question published by mxr is split to a separate thread with the subject Connect S7-1513-1PN & EUROTHERM NANODAC via PROFINET TCP/IP MODBUS.
