3. Diagnosis CPV−DI02 (PROFIBUS−DP)
Overview of the most important fault numbers
No. Operating status
0 No fault
2 Short circuit/overload in sensor supply
(SCS) or at output (SCO)
5 Undervoltage in the power supply (load
supply for outputs/valves, sensor supply for
input modules with additional supply)
11 Short circuit/overload at the valve
12 Pilot valve function warning
13 Wire fracture at valve (open load)
14 Valve: switching counter, limit value
exceeded
34 Incorrect string assignment ascertained
during operation (e.g. CPI module failed
or CPI cable defective)
More than one module failed during
operation modules are no longer
recognized.
35 The string assignment when the power
supply is switched on is not the same as the
saved string assignment or an incorrect
module is recognized during operation.
36 Short circuit in CP string
(24 V or 24 V
el/sen
Communication on CP string interrupted

Eliminating faults
Eliminate short circuit/overload
Eliminate the undervoltage in the relevant
power supply
Check valve
Recommendation: Replace the valve
Check valve
Recommendation: Replace the valve
Check CP strings (CPI modules and CPI

cables), if necessary replace CPI modules
or CPI cables
Switch power supply off and then on

again. If fault still occurs, check and, if
necessary, replace CPI cables and CPI
modules
Check CP strings (CPI modules and CPI

cables), if necessary replace CPI modules
or CPI cables
With correct string assignment: the string

assignment must be saved
Check string assignment, if necessary

replace CPI module
Check CP strings, if necessary replace
