Moreover we expressly declare that all obligations on the part of Wachendorff are
exclusively derived from the respective purchase contract, in which the guarantee is
conclusively stipulated.
2.5 Safety Instructions for the OPUS A8
Dangerous high-voltage
Never attempt to repair or modify OPUS A8 yourself.
Disassembling OPUS A8 may cause damage that is not covered
under the warranty and cause hazardous conditions by the
high-voltage components inside of the unit.
OPUS A8 does not contain any user-serviceable parts. Service
should only be provided by a Wachendorff Elektronik GmbH &
Co KG.
Hazardous situations due to device failure
Do not use the OPUS A8 as the sole means of preventing
hazardous conditions on vehicles, machines and equipment.
Vehicles, machines and equipment must be constructed in such
a manner that defective conditions associated with the OPUS
A8 cannot cause a hazardous situation for operating personnel.
Ensure that incorrect inputs via the OPUS A8, its malfunction,
or its failure cannot lead to major property damage, or to a
hazard for operating personnel.
Missing safety devices if used improperly
Precautions for the safety of a system should not be rendered
inoperable through the use of the OPUS A8.
Emergency-Stop devices must remain effective in all operating
modes.
WACHENDORFF is not liable for damage or malfunctions
occurs using pirated or illegal software on the OPUS operator
panel.
WACHENDORFF is not liable for injuries to third party licenses
for the contents used on OPUS panel by the end customer.

Safety instructions, guarantee and liability

Unintentional operation
Operating states can be called due to unintentional operation of
the OPUS A8 that are not appropriate for the situation.
OPUS A8 devices should be installed in such a manner that the
possibility of unintentional operation is adequately excluded.
If a further usage of the OPUS A8 will cause danger, the device
and if necessary the system needs to be switched off and be
secured against unintented activation. This particularly applies:
If the device shows visible signs of damage
If the device is no longer functional
If parts of the device are disconnected or loose
if the connection lines show visible damage
Undefined operating states
Undefined operating states can cause personal injury or
property damage.
To prevent supply line and signal line interruptions from
causing undefined or hazardous operating conditions,
appropriate hardware and software safety precautions must be
maintained.
Supply lines and signal lines must be installed in such a
manner that noise (such as inductive or capacitive interference)
cannot impair OPUS A8 function.
Using Connectors and Ports:
Never force a connector into a port. Check for mechanical
obstructions on the port. If the connector and port don’t join
with reasonable ease, they probably do not match. Make sure
that the connector matches the port and that you have
positioned the connector correctly in relation to the port.

3 Intended Use
The operator panel OPUS A8 is a programmable graphical display used to operate
and monitor vehicles and working machines.
The communication with other system components, as for example decentralised I/O
module, occurs over the CAN interfaces with the supported protocols: CANopen,
J1939 and CANfreestyle (layer 2).
For service purposes additional interfaces like Ethernet, RS232, USB and
analog/digital inputs/outputs (optional) are available. Together with Embedded Linux
operating system they form a universal platform for the communication with other
CAN devices, networks or PCs.
3.1 Example of Use
Control Unit 1
Controlling of the
actuation
Control Unit 2
Data logging from
sensors/switches
Control Unit 3
Controlling of
movement
Sensor 1
Sensor for
CAN-Bus
The operator panel OPUS A8 is not admitted for security-
relevant duties for personal protection purposes.
Vehicles, machines, and equipment surrounding the OPUS A8
must be combined in such a manner that the OPUS A8 will be
warmed up equally from all sides.
Increased warming of the OPUS from the back side may cause
temporary fogging of the front glass or touch screen.

Main connector:
The following interfaces are available:
Power supply and ignition input
2 x CAN-Interfaces according to ISO/DIS 11898
RS232-Interface
USB full speed
4 configurable analogue/digital inputs (optional), where input 1 work with
frequency 1-10 kHz and may also be used as frequency input, inputs 2-4
works with max signal frequency of 50Hz
3 digital outputs (option)
Audio-Out (option)
Video:
This interface is used for the analog Video-Input including protected camera power
supply as well as a digital camera control output (open drain). There is 1 video
interface available on the basic option unit and 3 video interfaces available on the full
option unit.
Ethernet:
There is an Ethernet interface (10/100 Mbit/s Base T) available on the unit. This
interface may only be used for data transfer.
Power-on/off behavior:
The OPUS A8 does not have a separate on/off key. As soon as the device is
supplied with the necessary voltage via terminal 30 (battery plus), terminal 31
(battery GND) and terminal 15 (ignition), it will start to boot. In order to decrease boot
time the device supports power modes with which you can put the device in a sleep
mode before it powers down.
When ignition voltage is removed, the device will switch to low-power-mode (see
C/C++ Developer Guide). After a time frame that can be configured (default time is
60 sec) the device will move one more step down to sleep-mode. After another 60
seconds (default time) the unit will fully switch off. As soon as terminal 15 is switched
on again the unit will go back to on-mode in full operation.

3.4 Application Development
There are three possible ways to program the OPUS A8 and make it an integrated
part of its application.
1. Projektor-Tool:
This powerful development environment provided by Wachendorff Elektronik GmbH
& Co KG enables the quick and effective creation of an application for the OPUS A8
operator terminal. Use the Projektor to conveniently design the user interface on the
computer, which can be easily displayed on the device. Additionally this tool includes
features to work with CANopen®, J1939 and CANfreestyle protocols for CAN
communication.
2. CODESYS© 3.x:
CODESYS© is a programming tool and system developed by the German company
3S according to IEC 61131-3 standard. It supports different means of programming
such as FUP (continuous function chart; CFC) or structured text. It can be used to
program the OPUS A8 and CODESYS© compatible ECUs. CODESYS© includes the
functionality to configure the CANopen® protocol for communication over CAN bus.
3. C-Programming:
OPUS A8 with its embedded Linux operating system can be fully programmed using
C or C++ as programming language.
For further information and function-call list please refer to the C/C++ Developer
Guide.

Technical Documentation
Page 12 of 26
4. ISO-UT:
OPUS A8 can be used as an ISO-UT slave in accordance with the ISO-11783
standard and DLG conformity.
5. Wachendorff Board Support Package (BSP):
Based on the operating system the Wachendorff BSP provides all the necessary
interfaces to control the internal functionality of the unit (e.g. activation of the display
backlight, processing key activation, etc.).
This software is ready installed on all OPUS A8 delivered together with the operation
system. For further information please refer to the C/C++ Developer Guide.
6. Universal Downloader:
To download software from the PC to the terminal the Universal Downloader 4 is
provided. It supports a download via USB stick and Ethernet. The Universal
Downloader 4 also stores the software, installs it and restarts the application on the
terminal.
Please take notice of the following recommendation and prerequisites for the
computer used to the application design and /or programming:
- Using Projektor Tool and CODESYS© for the development it is recommended
to use the PC with Windows XP (or higher) operational system (for
CODESYS© it may by younger), at least 2 GB free hard disk capacity and 2
GB RAM. Serial port is recommended.
- Programming with C/C++ Linux operational system is prerequisite.
3.5 Development Kit
For programming the graphical user interface of the OPUS A8 some different
development kits are provided.
The operator panel OPUS A8 may only be handled due to the
according operation manual.
