A program development support device for supporting development of a safety program to be executed in a safety controller includes: a development module that develops the safety program in response to user operation; a calculation module that calculates an identification value according to data of the developed safety program, in accordance with a function for calculating a random value with respect to an input; and an output module that outputs a document related to the safety program. The output module provides the identification value calculated by the calculation module to all pages of the document which are related to the safety program.

A system for processing data of a technical device of a technical system includes the technical device that detects measurement data within the technical system, a data storage device for storing measurement data and additional data relating to the technical device, a computing unit connected to the storage device that runs program code units that include a device interface unit that receives measurement data and additional characteristic data from the technical device and stores them in the data storage device, an analysis unit for providing selected analysis data for an operator of the system, wherein the selected analysis data is provided based on a unique identifier of technical device, a correlation of the measurement data and the characteristic data to the technical device, and preferably based on the access authorization of the operator, and a communication unit that visually provides the selected analysis data to the operator.
