Indicator Description
| Module status indicator | ||
| Indicator | Status | Description |
| US (coupler power indicator) | Green steady on | Us powered normally |
| Yellow indicator steady on | Under normal power supply, Us undervoltage (indicated when below 20 V) | |
| Off | Us not powered | |
| Note: When Ua is powered normally and Us is not powered, the Us indicator does not light red as an indication but remains off | ||
| UA (peripheral power supply indicator) | Green steady on | Ua powered normally |
| Yellow indicator steady on | Under normal power supply, Ua undervoltage (indicated when below 20 V) | |
| Off | Ua not powered | |
| Note: When Us is powered normally and Ua is not powered, the Ua indicator lights red as a reminder | ||
| BF (communication indicator) | Red indicator steady on | EtherCAT communication failure |
| Red indicator off | EtherCAT communication normal | |
| SF | Red blinking (1 Hz) | IO-Link configuration error: the configured bytes are fewer than the slave attributes (input/output byte counts), or the configured model is inconsistent with the actually connected model; IO-Link configuration exceeds 32 bytes |
| Red blinking (5 Hz) | IO-Link slave: digital DO output short circuit | |
| Red indicator off | No error | |
| XF1 | XF1 port communication indicator: the green indicator lighting up indicates an XF1 port communication connection | |
| XF2 | XF2 port communication indicator: the green indicator lighting up indicates an XF2 port communication connection | |
| Port indicator | ||
| Indicator | Status | Description |
