Digital Outputs
90
An Output can be "linked" directly to an Digital Input so that the output
"tracks" the input. When the input is closed, the Output will be energized,
and when the input is open, the output will be de-energized. This "tracking
will occur if two conditions exist:
– The Input is configured for any choice other than "Unused"
– The Output is configured for the appropriate "Input x Link"
Note that the output will continue to track or be controlled by the state of the
input, even if the input has been assigned a function (i.e. Start, Jog)
Output Time Delay
Each digital output has two user-controlled timers associated with it.
One timer (the ON timer) defines the delay time between a FALSE to TRUE
transition (condition appears) on the output condition and the corresponding
change in state of the digital output.
The second timer (the OFF timer) defines the delay time between a TRUE to
FALSE transition (condition disappears) on the output condition and the
corresponding change in the state of the digital output.
382 [Dig Out1 OnTime]
386 [Dig Out2 OnTime]
390 [Dig Out3 OnTime]
Vector
Sets the "ON Delay" time for the digital outputs. This is
the time between the occurrence of a condition and
activation of the relay.
383 [Dig Out1 OffTime]
387 [Dig Out2 OffTime]
391 [Dig Out3 OffTime]
Vector
Sets the "OFF Delay" time for the digital outputs. This is
the time between the disappearance of a condition and
de-activation of the relay.
Either timer can be disabled by setting the corresponding delay time to "0."
Important: Whether a particular type of transition (False-True or True-False)
on an output condition results in an energized or de-energized
output depends on the output condition.
If a transition on an output condition occurs and starts a timer, and the output
condition goes back to its original state before the timer runs out, then the timer
will be aborted and the corresponding digital output will not change state.
