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.
