Communication network aligning method for e.g. fabrication system, involves adjusting preset limiting value corresponding to temporal generation of quality parameter, which represents stale count limit in field device

摘要

The method involves determining a preset limiting value for a quality parameter, which represents a stale count limit in a field device (F1). The quality parameter is increased during the occurrence of a communication error between field devices (F1, F2), which serve as a receiver and a transmitter. The temporal generation of the quality parameter is measured and evaluated. The preset limiting value is adjusted corresponding to the temporal generation of the quality parameter.
