Switching the outputs requires a valid session. There is also a
corresponding table for the outputs:
wtWebioEA….InOut » wtWebioEA….OutputTable »
wtWebioEA….OutputEntry » wtWebioEA….OutputState

SNMP-SET, the output switches to ON – and sending a 0 turns
it OFF.

Communication paths >> Modbus-TCP

addresses are supported by the Web-IO.
