mation on any available standards or regulations regarding safety installations.
Before starting any work on devices, switch off all power feeds, including to peripherals.
Keep all ventilation holes unobstructed.
Failure in certain components in an electronic control system may result in uncontrolled and/or unpredicta-
ble operational behaviour.
All types of failure must be considered at the system level and the associated preventative measures
identified.
If necessary, request information from your automation system provider.

3. Product description
The DC2115 Dialog Controller is a control module with a display for the control and regulation of automation
and industrial processes in low-voltage installations in real time.
The CODESYS 3.5 (IEC 61131-3) development environment from 3S-Smart Software Solutions is used for
programming the device.
The Ethernet Terminal ET2115 is an input device with a display for connection to a control system for ma-
chines or systems. The terminal shows the CODESYS Web visualisation or CODESYS Target visualisation,
irrespective of whether the visualisation originates from a Berghof PLC control unit or some other CODESYS
control unit.
The Ethernet Terminal ET2115 can be connected via Ethernet interfaces; the Controller DC2115 can be con-
nected via different interfaces and has additional digital and analogue inputs/outputs.
The device connection area for all external connections is located at the rear of the devices. These devices are
intended for installation on a flat surface in a pre-prepared installation cut-out.
All connections are of the insertion type.
