DCS controller and AC 800M High Integrity safety controller

Overview

System Controller Connect is a software product

which is loaded and executed in a Symphony Harmony/Symphony Plus controller.

System Controller Connect supports Manufacturing

Message Specification (MMS) protocol in the Symphony Controller. The System Controller Connect

software is deployed as an MMS Client Application.

The AC 800M controller acts as a Server and responds to MMS commands sent from the System

Controller Connect client. The client application

reads/writes blocks of data in order to maximize efficiency.

This is accomplished by forming scan groups containing a set number of access variable values.

The System Controller Connect interface performs

non-SIL based communications that can be used for

‘high speed’ real-time data exchange communication.
