I have 4 Allen Bradley PLCs which are 3 SLCs and 1 CLX This PLCs need to send data to Yokogawa Centum VP DCS. Instead of having and individual Modbus link to DCS, I'm planning to link all 4 PLCs by using Ethernet/IP and plan to buy 1 extra mini PLC which is Micrologix 1400 to become an interface PLC between the 4 PLCs and the DCS. Since the Micrologix 1400 has embedded with an Ethernet port (Ethernet/IP) and Rs485 port for Modbus RTU, the Micrologix 1400 interface PLC will communicate with DCS using Modbus RTU Protocol. Meaning to say, the 4 PLCS will send data to the Yokogawa DCS via interface PLC. The Interface PLC will become translator to translate from Ethernet/IP language to Modbus RTU language.
My question to Expert:
1. Is this setup can works?
2. How to send data inter-PLC by using Ethernet /ip ? Is it just need to grab the tagname or there is an address for that?
3.Is Micrologix 1400 is capable to communicate with 4 PLCs using Ethernet/IP? Or just only 1 PLC?
