ATTENTION: Selection of "Hold" for Output State During Program mode and
Communications Fault mode prevents the output point from going to the
safe state, making the output point not suitable for a SIL or PL rated safety
function.
Set Output State During Program mode and Communications Fault mode to
"Off" to allow points to go to safe state.
Connection Fault Handling
You can configure FLEX 5000 output module behavior when a connection fault
occurs, that is, the connection between the owner-controller and the output
module breaks.
You must define the following:
• In standard and safety modules
– Immediate output behavior when the connection breaks
• In standard modules only
– Length of time that the output behaves as defined
– Output behavior if the connection remains broken when the length of
time that is defined previously expires

Output Behavior Immediately After a Connection Fault

ATTENTION: Selection of "Hold" for Output State During Program mode and
Communications Fault mode prevents the output point from going to the
safe state, making the output point not suitable for a SIL or PL rated safety
function.
Set Output State During Program mode and Communications Fault mode to
"Off" to allow points to go to safe state.
When the connection between an owner-controller and output module breaks,
the output can behave in the following ways, depending on how the
Communications Fault mode parameter is configured:
• Turn off - Default
• Transition to a specific, user-defined value
(This option is not available for Safety applications.)
• Hold its last state
