Diagnostic LEDs for local errors
Local error in a Coupler Box (IL230x-Bxxx/Cxxx)
The term local error means that an error has occurred in the Fieldbus Box or the IP-Link. IP-Link errors most often turn out to be a result of inappropriate use of the optical fiber.
LED green | LED red | Description | Remedy | ||
|---|---|---|---|---|---|
off | off | No data exchange | Module in synchronous mode or - activate PROFIBUS cyclic data | ||
off | 1 | 0 | EEPROM checksum error | Set manufacturer’s setting with the KS2000 software | |
off | 2 | Reserved | - | ||
off | 3 | Break location has been recognized | interruption before the master's receiver | ||
3 | n | Break location has been recognized | n-th module before the master's receiver | ||
3 | n | m | Break location has been recognized | (n*10)+m-th module before the master's receiver | |
off | 4 | n | Too many faulty telegrams have been detected (more than 25%) | The optical fiber wiring in front of the nth extension module should be checked | |
off | 5 | n | Register access to complex modules has failed | Check the nth module | |
off | 11 | n | Complex module working incorrectly | Exchange the nth module | |
off | 12 | n | More than 120 modules in the ring | Connect fewer modules | |
off | 13 | n | nth module unknown | Firmware update required | |
on | off | Module is exchanging data | no error | ||
Local errors in an Extension Box
LED green | LED red | Description |
|---|---|---|
off | on | No data is being received over the IP-Link |
off | blinks, flickers | Faulty IP-Link protocols are being received (very poor data connection) |
blinks, flickers | blinks, flickers | Faulty IP-Link protocols are being received (poor data connection), does not necessarily lead to an error |
on | off | IP-Link protocols are being received, no error |
Faulty protocols can occur, because of:
- bad configured IP-Link connectors
- IP-Link cable with higher dampening, e.g. because of a sharp curve
- contaminated sender LED (module before the faulty one)
- contaminated receiver
The internal IP-Link error counter of the Coupler Box can be read with the KS2000 software.
