4.1 Overview
Introduction
Implementation of the required automation functions is often possible with PCS 7 in various
ways. The work steps described in this document for project creation, configuration and
parameter assignment provide the basis for the PCS 7 application to be created. The following
aspects play an important role in this for the complete runtime of the system:
● Availability
The availability of the overall system can be influenced by appropriate actions in the PCS
7 application starting in the planning phase.
● Expandability
Expansions and/or changes will need to be made repeatedly following the initial
commissioning of a PCS 7 system. Attention must be paid to this when creating the PCS
7 application so that these can be executed more efficiently.
● Maintainability
According to the IEEE 610.12-1990 standard, software maintenance is understood to be
"the modification of a software product after delivery to correct faults, to improve
performance or other attributes, or to adapt the product to a modified environment".
● Legibility
Among other things, one of the principles of programming in IT theory is that the software
must be created legibly. The requirements are that the code is well formatted,
corresponding identifiers are used and meaningful comments are inserted. The following
points should be achieved or improved by adhering to these principles:
– Options for reviewing the software in order to improve its correctness and robustness
– Options for maintaining the software
– Options for expanding the software
The following section provides an overview of the topics in this section.
