1Count5V/500kHz

3.10 Behavior at CPU-Master-STOP

3.10
Behavior at CPU-Master-STOP
Setting the Behavior at CPU/Master-STOP
You can program what the 1Count5V/500kHz is to do in the event of the failure of the parent
controller.
Parameters
Turn off DO
Continue working mode
1
DO substitute a value
DO keep last value
If the mode is to continue during a change from CPU-/Master-STOP to RUN (startup), the CPU/Master must not clear the
1
outputs.
Possible solution: In the part of the user program that is processed during startup, set the SW gate control bit and transfer
the values to the 1Count5V/500kHz.
214
Status of the 1Count5V/500kHz at
CPU/Master STOP
The current mode is terminated, the gate
closed, and the digital output blocked;
comparison values 1 and 2 and the load
value are reset; the high and low limit
values, function and behavior of the digital
outputs and the integration time are handled
in accordance with the parameter
assignments.
The current mode continues, and the gate
and digital output retain their status.
The current mode is canceled, the gate
closed, and the digital output blocked;
comparison values 1 and 2 and the load
value are reset; the high and low limit
values, function and behavior of the digital
outputs and the integration time are handled
in accordance with the parameter
assignments.
When a pulse is output when the
comparison value is reached, the substitute
value is 1 only for the duration of the pulse.
The current mode is canceled, the gate
closed, and the digital output blocked;
comparison values 1 and 2 and the load
value are reset; the high and low limit
values, function and behavior of the digital
outputs and the integration time are handled
in accordance with the parameter
assignments.
What Happens if
New Parameters Have Been Assigned?
The changed parameters are accepted and
take effect.
The gate is closed, the current mode is
terminated, the digital output is blocked, and
the changed parameters are accepted and
take effect.
The changed parameters are accepted and
take effect.
The changed parameters are accepted and
take effect.
