[anooprc]

Hi,

We are trying to establish communication between Schneider HMISTO715 and TM221ME16R in both RS232 ,RS485 but we are not able to establish communication.

HMI not responding to the PLC.The pin configuration we have followed as per manuals.

Please guide us how we can establish RS232 or RS485 communication between the two.
