The PLC-ARM interface is a document in the form of interconnected tables.
It is the main document for designing data interchange (allocation of address space) between controllers and operator stations distributed in the APCS system. The design of APCS in terms of designing the program code consists in creating a document designed to reduce all technical solutions to one document “PLC-Workstation Interface”. Describes the distribution of variables to device memory addresses.
From the composition of this document, it is possible to single out the composition of the designed control and indication functions.The absence of this document in the project means either self-determination of the contractor in the scope of visualization, or lack of skills in creating automated control systems.
