1
RUN
The FB MON module assumes the RUN state if no error is present and neither the active
MonIn inputs nor the active Secure inputs request a safe state.
The outputs assume the following values:
Error=0
MonOut=1
MonDelOut=1
2
STOP
The FB MON module assumes the STOP state if the input FbRun is FALSE.
The outputs assume the following values:
Error=0
MonOut=0
MonDelOut=0
3
SAFE
The FB MON module assumes the SAFE state as long as at least one of the active MonIn
inputs and at least one of the active Secure inputs has requested the safe state.
The outputs assume the following values:
Error=0
MonOut=0
MonDelOut=0
4
ERROR
If the FB MON module detects an error, the FB MON module assumes the ERROR state and
transmits the corresponding Diag message to the GROUP module.
The outputs assume the following values:
Error=1
MonOut=0
MonDelOut=0
5
RESET
The FB MON module assumes the RESET state if no further error is pending after an error
has occurred and the ErrAck input of the corresponding group is set to TRUE.
The outputs assume the following values:
Error=0
MonOut=0
MonDelOut=0
6
START
The FB MON module assumes the START state if the Restart input is active and TRUE, in
order to wait for a rising and falling edge of the Restart input before entering the RUN state
and the outputs leave the safe state. This state can only be assumed if manual restart is
enabled in the configuration data.
The outputs assume the following values:
Error=0
MonOut=0
MonDelOut=0
