The State Variable for Digital Outputs

The state variable for a digital output is an unsigned integer with a value from 1 to 7

representing the following:

1 = no-vfield: the field supply voltage is at or below 18V dc for that channel.

Note: When the state variable is 1, the field voltage (<tagname.V>) is reported as

0mV.

2 = de-energized: the commanded state is FALSE and the channel is de-energized.

3 = no-load: the controller cannot detect a load connected to the channel field wiring,

or the load is below the minimum required channel load of 10mA when commanded

TRUE.

4 = energized: the commanded state is TRUE and the channel is energized.

5 = short-circuit: the controller has detected a short-circuit condition, irrespective of

the channel drive state.

6 = field fault: an external source is driving the channel to an energized state or a

voltage greater than 18V dc, irrespective of the channel drive state.

7 = faulted.
