Hi everyone, im still new at programming and need your help with my
This is my first time to program a VFD(altivar320 ATV320U04M2C). I will not be using NOE module. Im using my BMXP432020 cpu so i will be using the normal rj45 cable from PLC to my VFD. I read that if not using noe module, i must use the read_var and write_var block in unity pro(also my first time to use this block). I just need to give a start command to my motor via modbus serial and read vfd frequency. i already wrote the logic but im not pretty much sure if i did it correctly so i need some expert advise from you guys.
I attached some screenshots of the logic and communication parameters which i think schnieder provided.
ModbusReadParameters = array[0..3] of int
InputFromVfd = array[0..15] of int
ModbusWriteParameters = array[0..3] of int
CMD_Write = array[0..15] of int
AG_01 = Start command
Thank you
