Many messages can be output even with a limited number of remote inputs by combining the remote input, computation, alarm, and event action functions.

Eight different messages can be written by combining four remote inputs with eight internal switches.

  • D01–D04 are data types added with DXAdvanced, accepting remote input as contact input values.
  • S01–S08 are internal switches of functions added with DXAdvanced.
  • Alarms are represented with flags (internal switches) rather than relay output, and are set as "events" of the Event Action function.
