Response of technology module to CPU STOP
Meaning
The technology module remains fully functional. Incoming count pulses are pro-
cessed. The digital outputs continue to switch according to the parameter as-
signment.
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 transi-
tion: 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.
If a digital output with the function "At comparison value for a pulse duration" is
set at CPU stop, the digital output is reset after the pulse duration elapses.
The technology module is returned to its startup state after a STOP-RUN transi-
tion: The counter value is set to the start value and the digital outputs switch
according to the parameter assignment.
