Description
For the individual channels of the analogue output modules, monitoring of indi
vidual faults can be activated or deactivated (suppressed) independently of each
other. Active monitoring causes the following: The fault is:
sent to the CPX field bus node
displayed by the module common error LED.
Further infomation on these monitorings can be found under the description of
the relevant fault in section 5.5.1.
Bit
Bit 0:
monitoring lower limit
Bit 1:
monitoring upper limit
Bit 2:
behaviour after short circuit/overload at analogue output
Bit 3:
monitoring wire fracture/idling
Bit 4...6:
reserved
Bit 7:
monitoring parametrizing faults
Values
1 = active; 0 = inactive
Presetting bit 0...2:
1 (active)
Presetting bit 3:
0 (inactive)
Presetting bit 7:
1 (active)
Remark
Monitoring the upper/lower limit:
Monitoring the output values on the range limits defined with the parameters
Lower limit ..." as well as Upper limit ..." (depending on the data format
used, see sections 5.4.4 and 5.4.5).
Monitoring short circuit/overload at output:
Only effective for the signal range 0...10 V.
Monitoring wire fracture (idling):
Only effective for the signal range 0/ 4...20 mA.
The wire fracture monitoring is only effective if more than approx. 1 mA
output current is output.
Monitoring parametrizing faults:
The channel specific parameters Lower limit" and Upper limit" are checked
for non−permitted values during parametrizing.
The setting of the channel parameter Monitoring parametrizing faults" is only
effective if the module parameter Monitoring parametrizing faults" is set to
active".
