Design and performance evaluation of real-time communication architectures

For an in-depth analysis of the delay characteristics and to demonstrate the feasibility of a reduced architecture, a pilot implementation based on the token bus was performed in the author's laboratory. The theoretical and measurement results of this work are reported. It is shown that using the immediate response option in all situations within the intended field of application leads to greater delays. Problems such as the mapping of the application services-manufacturing message standard (MMS)-onto logical line control (LLC) services are discussed.<
