Method and system for the testing of applications on which can be used in a decentralized manner, programmable control units of an automation system

摘要

The invention relates to a system and method for testing of programs, which can be used in a decentralized manner in at least one programmable control unit (10) of an automation system are stored, and the control device (10) with a higher-level control unit (20) via a field bus (30) communicates, comprising the steps of:- in the test programs, at least a program variable as test variables (tv1, tv2) characterized,- by means of a cooperating with the programming environment of the superordinate control unit (40), said marked test variables (tv1, tv2) in the embodiment of the program identifies,- in a device description file (50) of the control unit (10), in the description of the process image by means of process values (pd1, pd2) on the field bus (30) a further process value (70) for each identified test variables (tv1, tv2) for the transmission of the contents of the test variable (tv1, tv2) is applied, and- the communications behavior of the control unit (10) for the transmission of the contents of the test variable (tv1, tv2) is adapted in such a way that the contents of the test variable (tv1, tv2) in the further newly applied process values (70) on the field bus (30) to the master control unit (20) are transmitted.
