I have two pneumatic controllers working with Modbus protocol. When tested it in real time, i am getting data error at the slave side. It is assumed to be because of EMI. Anybody knows any method (or idea) to analyze the effect of EMI on this data error?

Some helpful advice, when asking for help with an error ALWAYS provide the error code/flashing light/print out/etc.
I can think of several "errors" for a MODBUS slave that have nothing to do with EMI.
What led you to assume that EMI is your problem? How do you know you're even getting a data error on the slave end?
