Behavior At Cpu-Master-Stop - Siemens SIMATIC ET 200S Operating Instructions Manual

2.12

Behavior at CPU-Master-STOP

Setting the response to CPU/master STOP
You can configure the reaction of the 1Count24V to failure of the higher-level controller.
Parameter
Turn off DO1
Continue working mode
1
DO 1 substitute a value
DO 1 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 executed during startup, set the SW gate control bit and transfer
the values to the 1Count24V.
Leaving the Assigned State
Under what conditions does the 1Count24V leave the assigned state?
The CPU or master must be in RUN mode, and you have to make a change at the control
interface.

Status of the 1Count24V at CPU/master
STOP
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.
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.
