Response of the technology module to CPU STOP depending on parameter assignment
Reaction to CPU STOP
The technology module remains fully functional. Incoming count
pulses are processed. The digital outputs continue to switch
according to the parameter assignment.
The technology module outputs the configured substitute values at
the digital outputs until the next CPU STOP-RUN transition.
The technology module is returned to its startup state after a
STOP-RUN transition: The counter value is set to the start value
and the digital outputs switch according to the parameter
assignment.
The technology module outputs the values at the digital outputs
that were valid when the transition to STOP took place until the
next CPU STOP-RUN transition.
The technology module is returned to its startup state after a
STOP-RUN transition: The counter value is set to the start value
and the digital outputs switch according to the parameter
assignment.
