Status LEDs¶
The LEDs are located at the front of module. There are 2 different groups:
- The 5 system LEDs (PWR, NET, DC, S-ERR and I/O-Bus) show the operation status of the module and display possible errors.
- The 29 process LEDs (UP, UP3, inputs, outputs, CH-ERR1 to CH-ERR3) show the process supply voltage and the statuses of the inputs and outputs and display possible errors.
| LED | Color | Off | On | Flashing | 1x flash | 2x flash |
|---|---|---|---|---|---|---|
| PWR/RUN | Green | Error in the internal supply voltage or process voltage missing | Internal supply voltage OK | Module is not configured | – | – |
| Yellow | – | – | – | – | – | |
| NET | Green | Init | Operational | Pre-operational | Safe-operational | – |
| Red | No error | PDI Watchdog Timeout | Invalid Configuration | Unsolicited State Change | Application time out | |
| DC *) | Green | Distributed Clock not active | Distributed Clock active | – | – | – |
| Red | – | – | – | – | – | |
| S-ERR | Red | No error | Internal error | – | – | – |

| *) The status of this LED is only significant if the camswitch functionality is enabled | ||||||
| LED | Color | OFF | ON | Flashing |
|---|---|---|---|---|
| DC0 to DC7 | Yellow | Input/Output is OFF | Input/Output is ON | – |
| DI8 to DI15 | Yellow | Input is OFF | Input is ON (the input voltage is even displayed if the supply voltage is OFF) | – |
| DO8 to DO15 | Yellow | Output is OFF | Output is ON | – |
| UP | Green | Process supply voltage missing | Process supply voltage OK and initialization finished | – |
| UP3 | Green | Process supply voltage missing | Process supply voltage OK | – |
| CH-ERR1 to CH-ERR3 | Red | No error or process supply voltage missing | Internal error | Error on one channel of the corresponding group |
