In the past, Engine Control Systems (ECS) were considered as external units. They kept speed, load and air-fuel ratio constant and prevented the engine from exceeding critical limits. Nowadays, high-end reciprocating engines are mechatronic systems whose properties are significantly determined by the ECS software. Therefore, most combustion developments and mechanical design changes involve additional software development. Some engine manufacturers spend considerable effort in developing their own control systems, others are seeking for appropriate cooperation partners. OpenECS describes a way of cooperation between an engine manufacturer and a control system supplier and integrator, granting the engine manufacturer direct access to the control code. As in combustion development, where it is quite common to consult external engineering companies with long experience and powerful development tools, the engine manufacturer has the choice to develop the software in-house or to use external experts. The OpenECS platform supports the PLCopen programming languages as well as MATLAB/SIMULINK code. In the last 10 years, various PLC (Programmable Logic Controller) manufacturers have established PLCopen as a standard for PLC programming in industrial automation. PLCopen offers interfaces to major professional software development tools for debugging, testing, documentation, source code management and tracking systems. Many classification societies require the use of such established tools to proof sufficient software quality. AVAT provides a large library of gas engine specific software modules for the control of the gas engine and its periphery. Among others, it includes synchronization and generator protection functions, built-in diagnostic tools for service engineers and well-tested communication drivers for the integration of various external units such as ignition systems. The development of a specific engine application program typically starts from one of the standard application programs which are available for different engine types. AVAT is ready to support engine manufacturers in any phase of the development or to take on full responsibility for the application.
