1. On the Module Properties dialog box, click the Configuration tab.
2. Click the pull-down arrow to choose the Program Mode for each channel.
Options available are Off (default), On and Hold.
3. Click the pull-down arrow to choose the Fault Mode for each channel.
Options available are Off (default), On and Hold.
4. Specify Fault Duration.
When active, Fault Duration has options of "Forever", "1 Second",
"2 Seconds", "5 Seconds", or "10 Seconds". Default is "Forever" or 0.
5. Specify the Fault Final State.
Note that this is grayed out unless Hold Duration is something other
than "Forever". When active, Fault Final State has the options, "Off" and
"On". Default value is Off.
6. If communications fail in program mode, specify whether to "Leave
outputs in program mode" or "Change outputs to fault mode state".
7. Click OK.
Output State
The Scheduled Output module allows the user to define output state when in
Program Mode and Fault Mode.
Program Mode refers to the state where the following events occur:
•
Controller program is not executing.
•
Inputs are still actively producing data.
•
Outputs are not actively controlled and go to their configured Program
mode.
Fault Mode selects the behavior the output channel takes if a communication
fault occurs. Fault Value defines the value to go to on fault if the bit is set.
Fault Mode provides individual fault mode selection for output channels.
When this selection is disabled [the bit is reset (0)] and the system enters the
fault mode, the module holds the last output state value. This means that the
output remains at the last converted value prior to the condition that caused
the system to enter the fault mode.
