Tab. 5.3 Diagnostic/error messages by CPX error numbers
When the CTEL master module is accessed via FMT/MMI, the 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 the appendix (
è
A.2 Event codes).
5.3 Diagnostics via LEDs
LED indicators for diagnostics of the CPX terminal are available on the I-Port devices and on the CTEL
master module (
è
2.3 Display components).
The significance of the LEDs on the I-Port devices can be found in the description of the
respective device.
