ci867 Ethernet card with ethernet to rs 485 converter
Deal All,
Our plant is using a ci853 with rs232to rs485 which connects dcs abb80xa to ESD hima h7506 . now in revamp of our plant we are going to use CI867 with ehternet to rs485 (ADAM 4572) to ESD . my question is that if data transfer speed will be incressed with this configuration? I mean if ci867 will increase the speed of data?what about adam 4572 it will decrease speed or dose not change data transfer?

You can't increase overall data transfer speed unless you increase baudrate of Hima serial port. Maybe there is chance to optimize Modbus commands , for example to merge reading of several single coils or numbers into one read command.

Speed will remain more or less the same as before if not the baud rate is changed.
What kind of HIMA system are used?
If its a Planar 4 with several racks there could be an speed increase if you setup individual serial ports from the MODBUS RTU/TCP converter for each HIMA rack.
If it's an HiQuad you could use MODBUS TCP directly.
