Automation of specification process for PLC control systems software

摘要

The specification process for advanced industrial process control systems should be conducted by means of a methodology that takes into consideration the specification of control functions and the system architecture. For the domain of industrial process control by PLCs, we have implemented the automation of the specification process within a pragmatic low-cost and easy to use CASE environment, comprising commercial computer tools extended by a dedicated software. Such an environment makes possible domain-oriented non-redundant data entry, automatic data expansion and transfer into the CASE tool repository, and remains an advantage of CASE tool generic functions.
