Troubleshooting LED Indicators and Fiber Diagnosis
LED
Status
Description
Status/Troubleshooting
Ready
Flashing
green
Fiber diagnosis
finished
Check Fault LED;
At least one converter is in Fiber
Diagnosis mode;
Check PROFIBUS master settings;
Tx and Rx cables crossed
Flashing
red
Detecting
baudrate
No PROFIBUS node;
No PROFIBUS signal received;
Tx and RX crossed over;
Baudrate setting is incorrect.
Flashing
green/red
Slot time setting
error
Recalculate the slot time; Set
TSDR ≥ 11;
Set HAS = greatest PROFIBUS
node address + 1;
Check consistency of operation
mode for DIP switch 6/7;
Check consistency of Fiber Link
Monitor Mode for DIP switch 5
Fault
Flashing
red
Fiber
abnormality
occurred in
another segment
Use Fiber Diagnosis on another
converter that is not adjacent to
this converter
Solid red
Fiber
abnormality
occurred on this
converter
Check P1 and P2 LEDs
P1/P2
Flashing
red
Rx fiber cable
abnormality
Check the Rx fiber cable
connecting to this port*;
Tx and Rx cables crossed over;
Partner module is powered OFF
or
defective
Solid red
Tx fiber cable
abnormality
Check the fiber cable linking to Tx
of this port*
P3
OFF
PROFIBUS is idle
Check the PROFIBUS device
connection
Flashing
red
PROFIBUS side
error
RS-485 cable is not terminated or
only terminated at one end;
Open bus cable;
PROFIBUS D+ and D- crossed
over;
Short circuit on PROFIBUS cable;
RS-485 driver is defective;
Check slot time setting, baudrate,
and operation mode
If the abnormality indicated by the LED disappears in Fiber Diagnosis
mode, check the consistency of the DIP switch settings on all the
converters.
If the Tx
and Rx cables are both abnormal, the P1/P2 LED will shine red.
Check the Rx cable first for troubleshooting.
*If the Fault LED, P1 LED, and P2 LED are all lit/flashing red
simultaneously, the Tx and Rx cables of P1 and P2 may be crossed over.
