Table 3-24: State information (8-bit value)
RUN
The FB ESTOP module assumes the RUN state if no error is present and no active EStopIn
input requests a safe state.
The outputs assume the following values:
Error=0
EStopOut=1
EStopDelOut=1
STOP
The FB ESTOP module assumes the STOP state if the input FbRun is FALSE.
The outputs assume the following values:
Error=0
EStopOut=0
EStopDelOut=0
SAFE
The FB ESTOP module assumes the SAFE state as long as at least one of the active
EStopIn inputs has requested the safe state.
The outputs assume the following values:
Error=0
EStopOut=0
EStopDelOut=0
ERROR
If the FB ESTOP module detects an error, the FB ESTOP module assumes the ERROR state
and transmits the corresponding Diag message to the GROUP module.
The outputs assume the following values:
Error=1
EStopOut=0
EStopDelOut=0
