Version 2
In addition to the functions shown above, the LEDs also indicate various controller operating states. These states
are described in detail in the table below:

EtherCAT

communication
The following sections only describe controller-specific functions. For general information on the EtherCAT
®
inter-
face and the system configuration, please refer to the description of your PLC.
The controller can communicate via the EtherCAT
®
interface provided the 24 VDC supply voltage (terminals 5+7)
is present.
As long as no line voltage is present, the controller remains in an inactive status.
But interruption of the line voltage (e.g. by being switched off when a door is opened) triggers the error message
201 (error group no. 7, network voltage/sync signal is missing) and the Alarm relay switches. This is caused by
the lack of line voltage. The error message can be reset by switching on the line voltage again and setting the
RS bit (
section 8.5.3 "Reset (RS)" on page 23).
You can easily process the error code that appears if the line voltage is switched off – or suppress switching of
the alarm relay – in the PLC program.
