number
Error handling Description of possible causes
17 Incorrect I/O length
CPX system start with setting “Stored
parameters” and CTEL master module in
operating mode “Automatic configura­
tion”
Use system setting “Standard
parameter” at the start of the CPX
terminal
24 Process variable range underflow Process data inconsistent, check
25 Process variable range overflow Process data inconsistent, check
29 Parameter error
Invalid parameters received from the

Missing parameters Check data sheet
Changed parameter Check configuration
39 Maintenance required Process data inconsistent, check
56 Short circuit at I-port (PS/PL supply or
communication signal)
Check the installation
57 I-port device missing/failed Check configuration
58 I-port configuration error Check configuration
Tab. 5.3 Diagnostics/error messages by CPX error numbers
When the CTEL master module is accessed via FMT/MMI, the most current error for each
I-port can be determined more precisely by means of an event code if the error is due to
the connected device.
A list with the relevant event codes can be found in appendix A.2.
5.3 Diagnostics via LEDs
LED indicators for diagnostics of the CPX terminal are available on the CTEL master module and the
I-port devices.
