Status/Input - RE: I/O map register assignments (Inputs).
Allow Automatic Restart of Faulted Points:
NO: Module outputs that fault during the on state are latched off until the user clears
the point bit to the OFF (0) state, and then sets it back to the ON (1) state.
Status/Input
Verified Health
Verified Fault
Input Only
Actual
Verified Health: The associated bit = 1 when the point output command and
module output state agree
Verified Fault: The associated bit = 1 when the point output command and
module output state disagree.
Input Only: Input module operation for diagnostic purposes only. When an
output point has a high applied, the associated 1x bit or 3x register location =
1.There are no specifications for output terminals read as inputs and the DVO
should not be operated as an input module in a system.
If the corresponding 4x register point is turned OFF, a high will also cause the
LED display red F to appear and a group miscompare bit will set in the I/O Map
status byte. If the corresponding 4x point is turned ON, no LED ref F or group
miscompare will be displayed when a high is applied to the output point.
The status byte voltage fault bits work in this mode.
Actual: Module output state, 1 = ON
ALLOW AUTOMATIC RESTART OF FAULTED
NO
YES
