Communication for PLC AC500 use IDS-5012
I want connect 1 PLC AC500 with PLC AC800M system. I use Modbus protocool to communication. My system has one converter to convert signal (IDS-5012 converter has 1-port RS-232/422/485 to 2 port LAN serial to Ethernet device). 1-port to be connected with PLC AC500, 2-port to be connected with Hub switch(1 for Main, 1 for redundant). I don't know this solution can be implement? Please support for me. Thanks so much!

Since you are using Redundant AC800M controller you cannot directly connect to Ac500 controller. You need to choese between Modbus or Modbus TCP protocol to communicate.
AC500(PM5xx-ETH) Ethernet PLC will support Modbus TCP and Modbus RTU, Non -ETH PLC only supports Modbus RTU protocol.
If you select Modbus RTU you need to use CI853 comminication module in AC800M to connect with AC500
If you select Modbus TCP the you need to use CI867 communication module in AC800M to connect with AC500
Unfortunately I am not expert with AC500 and AC800M, but with the information I have. I am not sure why you need any convertor ? If I am not wrong both controller + comunication module, supports modbus TCP you can use that directly.
Why you are using this convertor ? Will try to get more information.
Looking forward for more info from some expert of this topic.
