6.4.6 Surveillance Timeout Configuration (LioN-P 60
devices)
For LioN-P 60 devices, the separate power supply 2L+ (UAux), which is
available on type B IO-Link channels (Ch.B / Pin2), ports 5-8, can also be
configured as an additional digital output (tab: "Digital-IO mode for Ch. B
(Pin2)". This gives you the option of switching the power supply like a digital
output.
The firmware of the modules allows you to configure a delay time before
output current monitoring is enabled for this special use case.
The delay time is referred to as the "Surveillance-Timeout" and can be
configured for each output channel. The delay time begins after the state of
the output channel changes, i.e., when it is activated (after a rising edge) or
deactivated (after a falling edge). After this time has elapsed, the output is
monitored, and error states are reported by diagnostics.
The "Surveillance-Timeout" parameter can be set from 0 to 255 ms. The
default value for this parameter is 80 ms. When an output channel is in static
state, i.e., when the channel is permanently switched on or off, the typical
value is 5 ms.
