HI, I will change a damaged PLC, Not Siemens. that control around 40 Fans, the original instalation have a Central PLC and 5 MODBUS RTU slaves each one with 10 Digital Input and Output. The old PLC have 3 communitation ports, so have 3 main Cables, one for port, 2 slaves in Port1 and Port2 and one in the port3. The salves aren't near, but in the 800 Metres range, max 200 metres between each one re-wiring to conect all slaves in only main cable, is not viable. I have plan to use a 1211C and a CM1241, in detail a CM 1241 RS422-485 - 6ES72411CH320XB0 But the CM only have 1 port. So, I can use a RS485 Hub/Splitter like this https://www.commfront.com/products/industrial-opto-isolated-rs485-hub-splitter?variant=9077058115 or another can recommend, work with that CM? grateful in advance |
