Description
In the case of a malfunction of the
PROFINET IO communication, the
status of the connected output
periphery can be influenced in various
ways.
The process data exchange on the
internal bus is stopped, all outputs
drop out after a module specific
monitoring time of 100 ms.
All outputs are immediately reset.
All outputs maintain the last status
before the malfunction.
All outputs switch the substitute value
configured when designing the
module.
In the event of a malfunction of an
internal communication between
fieldbus controller and I/O modules,
such as, for example no end module.
Separates the cyclic connection to the
PROFINET IO controller.
The input information of the
respective periphery module is set to
zero.
The input information of the
periphery module prevailing before
the fault is maintained.
