8.6 Overload/short circuit of the type B
port aux. power supply
Technical manual LioN-P PROFINET IO-Link Master
Release 2.0 04/2017
When an output channel is activated (rising edge of the channel state) or
deactivated (falling edge), the channel errors are filtered for the period that
you set using the "Surveillance-Timeout" parameter during the configuration
of the module. The value of this parameter can range from 0 to 255 ms; the
factory setting is 80 ms.
The filter is used to avoid premature error messages when a capacitive load
is activated or an inductive load is deactivated, and during other voltage
peaks when a status changes.
In static state of the output channel, that is, while the channel is permanently
switched on or off, the filter time between error detection and the diagnostic
message is typically 5-10 ms.
The device sends the following PROFINET diagnostic message in this fault
case:
8.6
Overload/short circuit of the type B port
aux. power supply
8.6.1
