NVH Posts: 2 Rating: (0)	Hi All, I have S7-400H PLC and ET200M rack(IM153-2). There is a requirement that I need to receive signals from field over Modbus TCP/IP. I found this module CP343 lean. But this module is compatible with IM360 and not IM153-2. this is what I got to know from data sheets that I read. Want to know if it is correct? If so then What is the best solution ?? Should I include one more rack for IM360 or there is any alternative module, which I can usewith IM153-2 itself. Thank You, NVH

Either you use internal Ethernet port on CPU (if available) or CP443 togehter with OPEN MODBUS TCP software library. Open Modbus-TCP information here: https://www.industry.siemens.com/services/global/en/IT4Industry/products/simatic_add_ons/s7_open_modbus_tcp/Pages/default_tab.aspx?HTTPS=REDIR&tabcardname=technical%20data Best Regards.
