Yes, this can be done by setting up a MSTR to do a CTE read and or write to the NOE module. In order for the configuration change to take effect you must follow the CTE write with an MSTR reset. Refer to the Modicon Ladder Logic block Library Users Guide part number 840USE10100 for the MSTR Control block Utilization. The MSTR function operation types are as follows. CTE READ= 11, CTE WRITE= 12, RESET OPTION= 10.
