Default value: All bits default to 0
Bit = 0 The system software does not evaluate the bits in the corresponding interface
byte for operational messages.
Bit = 1 The system software evaluates the bits in the corresponding interface byte for
operational messages.
Notes:
1) The bit applies to all NC channels.
2) If the same bit is also set for error messages (PLC MD 6032, 6033), the PLC goes into the
Stop loop.
