Abstract

The purpose of the paper is to propose a simple experimental method to evaluate the execution time in programmable controllers. First, features of the cyclic scan are examined experimentally by fundamental programs for evaluation. Second, the experimental evaluation method of the execution time of LDs and SFCs using stochastic tests is established. Furthermore, discussions on the evaluation method of other functions, the design for programming, and application to the real systems are also given
