Ethernet based communication

The System Controller Connect provides a dedicated, high speed, and secure interface between

Symphony Harmony/Symphony Plus systems and

800xA systems/safety systems.

Applications

The System Controller Connect software can be

used in applications requiring a:

• Fast and reliable interface between electrical and

process controllers

• Controller Connectivity for real-time data exchange in mixed systems

• Interface between Symphony Harmony/S+ based

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.

Features and benefits

• Transfer of 800xA tag values to the Symphony Harmony / Symphony Plus system using MMS protocol.

MMS is a native protocol of the System 800xA

AC 800M controllers and thus needs minimal configuration effort and no additional hardware components.

• MMS access variables in the AC 800M controller

are supported in the user friendly interface. Entries are defined as either read or write.

• Communication rates are fully tunable to meet requirements.

System 800xA values now available within the Harmony blockware can be displayed in the Symphony

Harmony HMI.

System Controller Connect supports a fully redundant interface. Redundant failovers are ‘bumpless’.

Redundant Ethernet address of the AC 800M controller using RNRP is fully supported.
