The Surveillance Timeout parameter
This parameter is provided by the module types with digital outputs
(16DO, 8DI/DO).
The firmware of the modules allows you to define a delay time before the
monitoring of the output currents begins, known as the surveillance
timeout. You can define this for every individual output channel.
The delay time begins after the status of the output channel changes, i.e.
when this is activated (after a rising edge) or deactivated (after a falling
edge). After this time has elapsed, the monitoring of the output begins and
the diagnosis reports error statuses.
The value of the surveillance timeout is 0 to 255 ms. The standard value
is 80 ms. When the output channel is in the static state, i.e. the channel is
permanently switched on or off, the value is 100 ms.
5.4.5 Prioritized startup
Prioritized startup is not supported by LioN-P/-R modules. Do not select the
"Prioritized startup" field in the "Properties - Interface (X1)" window for this
reason.
