6 Start-Up and Diagnosis
6.1 Run-up and error indications
After the supply voltage connection the coupler/controller checks all the functions of its components and the communication interface. The configuration of the I/O modules is then determined. The 'I/O ERR' LED is blinking during the run-up time. The coupler/controller enters then the "fieldbus start" status after the successful run-up. The green "I/O RUN" LED indicates this status. If an error occurs, the red "I/O ERR" goes on blinking in a low frequency. The various types of error are indicated via up to 3 different flash sequences.
Display functions of the 'I/O ERR' LED:
1. Coupler/controller’s start-up phase after the supply voltage connection
2. Introduction of the error indication
3. Error code
(number of flash cycles 2nd flash sequence)
4.Error argument
(Number of flash cycles 3rd flash sequence)
