METHOD FOR OPERATING A CYCLICALLY WORKING AUTOMATION CONTROL, AUTOMATION CONTROL AND ENGINEERING SYSTEM

摘要

procedures for the operation of a cyclically operating automatisierungssteuerung, automatisierungssteuerung and engineering system;the invention relates to a method for operation of a cyclically operating automatisierungssteuerung (10).although within a cycle time (zz) the automatisierungssteuerung (10), the following steps are executed:1. parsing of input data (ed) by a first periphery (a).2. storing the input data (ed) in a prozessabbild memory for arrivals (pae)3.start a anwenderprogramms (ap)although a majority of programmanweisungen on the basis of the prozessabbild memory for arrivals (pae) stored input data (ed) data (ad) to create4. storing the data (ad) in a prozessabbild memory for outputs (paa) after execution of the last programmanweisung,5. write the data (ad) from the prozessabbild memory for outputs (paa) to a source periphery (from)with a backup of persistent data (rd) within a time window (zf) is carried out, which is the end of the 3. step opens and at the beginning of 1.step back.
