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.
If no line voltage is present however (e.g. if it is switched off in order to open a door), error code 901 or 201 (error
group 7, no line voltage / sync signal) appears on the controller and the alarm relay is switched. This happens due
to the absence 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 26).
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.

EtherCAT
®
Slave Information (ESI)
The configuring tools for the EtherCAT
®
controller interpret the content of the slave information file (ESI) and use
this information to create a parameter set for the EtherCAT
®
controller which controls user data traffic. The ESI file
ROPEX RES-5012 UPT-6012 V1.2.xml
of the RES-5012 contains all essential controller information for the con-
figuration, e.g. the I/O data description, parameter descriptions, error messages etc. The ESI file can be requested
by e-mail (
) or downloaded from our website (
If the controller already has an IP address, the device description file can also be downloaded from the integrated
web server.
After linking the required ESI file into the configuring tool, you can select the desired parameter values.
