Why does the Error LED of my PCD2.M127 blink?

FAQ #101472

The Error LED of the PCD2.M127 does blink in case a PCD2.F7xx module is configured but the communication (Profibus or LON) is not working (e.g. because the module itself or a configured Profibus DP slave is not present).


The user documentation states that the Error LED can be programmed in the user program; this statement is wrong as the blinking error LED can only be stopped by either avoiding the failed communication or by removing the communication configuration from the project.
