Method for suppressing input unit errors in control devices uses memory-programmable controls to regulate bus traffic and overall data transport over a connected bus system in a master function

摘要

A controller (1) includes memory-programmable controls to regulate bus traffic and overall data transport over a connected bus system (3) in a master function. Local units on a bus fetch data from a process (6) or send data to it. An input unit (4) is connected to sensors to pick up their measurement values for sending to the controller via the bus system. An output unit (5) receives data processed by the controller via the bus system to feed it into the process for operation.
