EtherNet/IP
TM
communication
The following sections only describe controller-specific functions. For general information on the EtherNet/IP
TM
interface and the system configuration, please refer to the description of your PLC.
The controller can communicate via the EtherNet/IP
TM
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 24).
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.

Device description file (EDS)
The configuring tools for the EtherNet/IP
TM
scanner interpret the content of the device description files (EDS) and
use this information to create a parameter set for the EtherNet/IP
TM
scanner which controls user data traffic.The
ROPEX_RES-5011_V2_4.eds file of the RES-5011 contains all essential controller information for the configura-
tion, e.g. the I/O data description, parameter descriptions etc. The device description files and the associated
image files (.BMP and .ICO) 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. Alternatively, you can download it from the controller via the file object using CIP services.
After linking the required device description file into the configuring tool, you must assign an IP address to the con-
troller. DHCP is activated by default to enable the controller to request an IP address from a DHCP server in the
network. You must also select the desired parameter values.
