  1. 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
  2. PID IN FX2N

    I am going to write a program in GPPW (version8) on liquid flow control. There is 6 nos of PID loops in the process. I never used PID instruction before. Should I use 6 nos of PID instruction? Will it slow down the output response? Sudip
