Fault handling
Under/overshoot monitoring
The output saturation values according to the range are as follows:
Ranges Saturation value
+/- 10 V
0-20 mA
4-20 mA
Values provided by the application
Less than -10000
More than + 10000
Less than 0
More than + 10000
Less than 0
More than + 10000
- 10 V
+ 10 V
0 mA
20 mA
4 mA
20 mA
An overshoot bit which can be used by the program is then set to 1:
Bit address
%Ix.i.ERR
%MWx.i.2:X1
Meaning
Fault on channel i of module x
Range under/overshoot fault
Output fallback When the PLC switches into STOP mode, the outputs take the fallback value 0 (4mA in the range 4-20 mA) or are maintained at the last transmitted value, according to the selection made during configuration (See Modification of the Fallback Mode,
p. 249) of the module.
When dialog with the processor is no longer possible, the outputs take the fallback value 0 V (voltage range) or 0 mA (current range).
