Module Configuration, Output, and Input Data Chapter 4
Output Program Value (Out0ProgramValue through
Out3ProgramValue)
These bits are the values that will be applied to each of the real outputs when
User-defined Safe State (UDSS) is set as described and the module is in Program
state.
Output Fault Mode and Output Fault State Run
Output Fault Mode (Out0FaultMode through Out3FaultMode)
These bits configure the output for Hold Last State or User-defined Safe State
during a Fault state.
• 1 = Hold Last State
• 0 = User-defined Safe State
Output Fault State Run (Out0FaultStateRun through Out3FaultStateRun)
Similar to Program State Run, Fault State Run lets you specify, on a bit basis, that
the output should continue to be controlled by the module as if it were Run state.
That is, events on the module or changes in the output image will affect the
physical outputs without regard to the Fault_HLS or UDSS state indicated.
When this bit is set, the corresponding Fault mode and fault value bits are
ignored.

ATTENTION: Selecting this option lets outputs change state while ladder
logic is not running. You must take care to make sure that this does not
pose a risk of injury or equipment damage when selecting this option.
IMPORTANT
The prescan initiated by some controllers could have an effect on the
outputs. To overcome any changes in physical output states caused by
this, retentive output instructions (for example, latch or unlatch) should
be used when bit manipulations are done on the output image of this
module in ladder logic.
This applies to a wide range of bits when Fault State Run is selected,
because presetting a counter, enabling a range, changing a mask, and
changing Configuration Array settings can cause ranges and outputs to
change state.
