The CPX terminal offers extensive possibilities of diagnosis
and error treatment. The input module supports the following
diagnostic and error handling facilities:
Brief description
The LEDs on the input module display errors in
the input channel and modules.
On the operator unit, diagnostic information
from the input module can be displayed
conveniently with menu navigation.
8 status bits of the CPX terminal display
common diagnostics messages (global error
messages)
CPX-F8DE-P reports specific faults as fault
numbers to the bus node. The I/O diagnostic
interface enables these data to be
interrogated.
Dependent on the bus node (e.g. DPV1)
Reported errors can be evaluated, depending on the bus pro­
tocol used. The errors are indicated on-site via the Error LED
and, if necessary, can be evaluated with the operator unit.
Information about the diagnostic options on the complete
CPX terminal and/or all modules can be found in the CPX
system description and/or in the description of the bus node
employed.
Note
Ensure that the diagnostic messages cannot be evaluated
for safety-related measures.
