Abstract :
Control systems for industrial processes are more and more using PC-based platforms instead of dedicated devices such as controllers or PLCs. Software packages allow running a "soft PLC" on a normal PC with a general purpose operating system. These solutions present several advantages in terms of flexibility, communications, multi-vendor interfacing, and costs. On the other hand the use of multi-tasking operating systems does not guarantee a-priori respect of the time constrains that control applications present. The paper describes a procedure for measuring the time performances of a soft-PLC with different configurations and loading. Results of preliminary measures are presented and discussed.
