sudippanda Posted January 19, 2006 Report Posted January 19, 2006 In a running project I am making communication between FX-2n PLC and FRF-540J Inverter through FX2N RS485BD.There are 4 nos of drive. In our present program we can read the output frequency from the drives and can write the speed reference to the drive which has been tested successfully. I also need to give run command and stop command to the drives through RS communication. My program with frequency read & write is enclosed. Please help? Sudip 4_Drive_communication.zip Quote

swimmy67 Posted January 24, 2006 Report Posted January 24, 2006 Here is a program that I am using to communicate between 3 FR-E540 drives and 1 FR-A540 drive. This program uses the RS instruction for communications. I hope this helps. swimmy67 4_Drive_Communication.zip Quote
