Profibus Error Monitoring and Indication
Monitored Functions
• Connection to the master: Error for example by disconnecting the bus
cable.
• Baud rate identification
• Receipt of process data from the PROFIBUS
After receipt of a valid telegram, the next telegram must arrive within
the time set in the converter parameter "USIP timeout".
• Receipt of process data from the converter: If the connection to the
converter is interrupted, an error message is indicated in the
PROFIBUS telegram in the extended diagnosis (2 bytes: 0x02 0x04).
In parameter P746, the status of the PROFIBUS module can be read out.
With FCS01 devices, this can be done by means of a function module
FCC01.0F-PBx. There are 2 diagnosis LEDs at the function module.
Parameter P746 is a sub-index parameter: The status of the function
module FCC01.1F-PBx is indicated in sub-index 0.
LED Indication at the Function Module FCC01.1F-PB1
The two integrated LEDs signal the status of the function module:
