Meaning

1

EtherCAT status

See chapter EtherCAT

2

Switching status of the digital outputs, Channel 1

Off

All digital outputs on Channel 1 are low

Green

One or more digital outputs on Channel 1 are high

3

Error state of the digital outputs, Channel 1

Off

No error

Red

Short circuit at one or more outputs of Channel 1 1)

4

Switching status of the digital outputs, Channel 2

Off

All digital outputs on Channel 2 are low

Green

One or more digital outputs on Channel 2 are high

5

Error state of the digital outputs, Channel 2

Off

No error

Red

Short circuit at one or more outputs of Channel 2 1)

6

Status of UP

Off

UP is not connected

Green

UP is on

7

Status of US

Off

US is not connected

Green

US is on

1) Depending on the configuration, the status LED may continue to glow red after the short circuit has been cleared, since the affected digital output is not automatically reactivated.
For more information on this behavior, see the chapter Behavior in case of short circuit.

Short-circuit detection is achieved by comparing the desired state (high) with the actual state.
