Response to CPU/Master STOP
Select how the module's outputs will respond to a CPU STOP:
● Shut down
The I/O device goes to the safe state. The process image output is deleted (=0).
● Keep last value
The I/O device retains the last value to be output before STOP.
● Substitute value
The I/O device outputs the value for the channel set beforehand.
Note
Make sure that the plant is always in a safe state if "Keep last value" is selected.
Type of output
With this parameter, you set the output type, for example, voltage. For any unused channels,
select the disabled setting. For a disabled channel, the conversion time and integration time
of the channel = 0 s, and the cycle time is optimized.
Output range
With this parameter, you set the output range of the selected output type.
Diagnostics, wire break (in current mode)
When this parameter is enabled, the Wire break diagnostics event is generated when a wire
break is detected. This diagnostics event cannot be detected in the zero range.
Diagnostics, short circuit (in voltage mode)
If you enable this parameter, a diagnostics event is generated in the event of a short circuit
in the output line. This diagnostics event cannot be detected in the zero range.
Diagnostics, overload
If you enable this parameter, the diagnostics event is generated in the event of an overload.
Substitute values
With this parameter, you enter a substitute value that the module is to output in CPU-STOP
mode. The substitute value must be in the nominal range, overrange, or underrange.
