4.2.2 Status LEDs
4.2.2.1 Supply voltages
Fig. 3: Status LEDs for the supply voltages
EtherCAT P Box modules have two LEDs that display the status of the supply voltages. The status LEDs are
labeled with the designations of the supply voltages: Us and Up.
A status LED lights up green when the respective supply voltage is present.
A Status LED lights up red if the respective supply voltage is short-circuited.
4.2.2.2 EtherCAT
Fig. 4: Status LEDs for EtherCAT
L/A (Link/Act)
A green LED labeled "L/A" or "Link/Act" is located next to each EtherCAT/EtherCAT P socket. The LED
indicates the communication state of the respective socket:
LED Meaning
off no connection to the connected EtherCAT device
lit LINK: connection to the connected EtherCAT device
flashes ACT: communication with the connected EtherCAT device
Run
Each EtherCAT slave has a green LED labelled "Run". The LED signals the status of the slave in the
EtherCAT network:
LED Meaning
off Slave is in "Init" state
flashes uniformly Slave is in "Pre-Operational“ state
flashes sporadically Slave is in "Safe-Operational" state
lit Slave is in "Operational" state
