RS 485 serial communication between PLC and multiple drives
Hello ,
I have Ac500 pm554 tp ETH Plc and Four ACS560 drives . I need to achieve serial communication between plc and all other vfds. I want to use inbuiled port of PLC com1 port as a master. Is it possible or not ?.
Then any one can tell me how to send on and off controls to all VFD by plc.
Thanks in advance.

Hi,
Yes it is possible to make COM 1 port as RS485 master and can communicate to the RS485 slave in your case it is ACS560 drive.
you can use COM_MOD_Mast block to send the command to the RS485 slave.
