Diagnostics
The internal communication bus between the SIDOOR controller and the communication
module is monitored by the master driver of the communication module (PROFINET module). A
PROFINET diagnostic alarm is triggered if communication is interrupted or quality becomes too
poor. This diagnostic alarm is then present for at least 5 seconds and is structured as follows:

IO Controller
A PROFINET IO controller has control over the field devices. The process data and alarms arrive
in the IO controller and are processed in the user program. In an automation system, an IO
controller is normally a programmable logic controller (PLC). The communication channels are
established by the IO controller during system startup.
