Scenario: F-communication error<br />

Disconnecting the F-CPU and the decentralized station (unplugging<br />

the PROFIBUS DP cable) causes passivation of the entire<br />

F-I/O-modules in the distributed station.<br />

After restoring the connection (plugging the PROFIBUS DP<br />

cable back in) the F-I/O-modules remain passivated. The<br />

switched on PASSIVATION_ON indicator light indicates this.<br />

If the user acknowledges via ACK_PASS_ACTUATOR, the F-I/O<br />

is reintegrated.<br />
