Abstract

Today, most slow control systems for physics experiments at Forschungszentrum Jülich are implemented with Programmable Logic Controller (PLC) technology and fieldbus systems. In many cases, even deterministic response is required from the PLCs. This raises the question about the real-time performance that can be expected from a PLC. Response-time measurements of Simatic® PLCs-manufactured by the world market leader Siemens-are presented. Influence of program structure and hardware configuration on performance and deterministic behavior of a PLC is discussed.
