Indicator Description

Module status indicator
Indicator Status Description
US (system power indicator) Green steady on Us powered normally
Yellow indicator steady on Under normal power supply, Us undervoltage (undervoltage is indicated when below 17 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 (undervoltage is indicated when below 17 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 EtherNet/IP communication failure
Red indicator off EtherNet/IP communication normal
SF Red indicator steady on Configured byte count inconsistent with the actually connected module byte count (configuration error)
Red blinking (1 Hz) IO-Link configuration error: the configured bytes are fewer than the IO-Link slave's input/output bytes, or the configured model is inconsistent with the actually connected model; IO-Link configuration exceeds 32 bytes
Red blinking (5 Hz) IO-Link digital slave DO output short circuit
Red indicator off No error
XF1 XF1 port communication indicator: the indicator lighting up indicates an XF1 port communication connection
XF2 XF2 port communication indicator: the indicator lighting up indicates an XF2 port communication connection
Port indicator
