Reaction To Cpu Stop And Cpu Stop To Run - Siemens SIMATIC S7-300 FM 350-1 Manual

5.8

Reaction to CPU STOP and CPU STOP to RUN

Behavior at CPU-STOP
The behavior of the FM 350-1 when the higher-level controller fails is set using the Basic
Parameters dialog box (shortcut menu Object Properties > Basic Parameters).
Table 5- 25
Basic parameters
STOP
Continue operating
Terminate active job
Substitute value
Keep last value
Behavior during CPU STOP-RUN transition
The FM 350-1 behavior at the CPU transition from STOP to RUN if the job is continued or in
response to plant changes during operation using CiR is set using the Basic Parameters
dialog box.

FM 350-1 reaction to CPU STOP
The FM cancels the counting operation and switches off the outputs.
The FM continues working and does not switch off the outputs.
For single counting, the counting operation is continued until it is ended by
reaching the counting limit.
For periodic counting, the current counting operation is continued until it is
ended by reaching the counting limit.
Measurements are cancelled immediately.
The FM then switches off the outputs.
The current Count mode is cancelled. The module outputs the set
substitute values to the digital outputs. The substitute values are retained
after the CPU STOP-RUN transition until the next time the digital outputs
are used. The outputs are reset when you change the "Reaction to CPU
STOP" with new parameters.
The current measuring mode is cancelled, and the outputs are reset.
The current counting or measuring mode is cancelled. The module outputs
at the digital outputs the values that were valid at the time of canceling until
the next time the digital outputs are used after the CPU STOP-RUN
transition.

the basic parameters
FM 350-1 Reaction to New Parameters at the CPU STOP-RUN
Transition
The FM cancels the counting and measuring operations, resets
itself and accepts the new parameters.
The FM only cancels the counting and measuring operations if the
parameters have changed.
