Product Family

The ABB Triguard SC300E TMR product family gives unrivalled performance in areas of reliability, availability, test coverage,

diagnostics and simplicity of operation. Advances in technology and improved production methods add cost benefits that

give significant price/performance advantages.

• Fewer unscheduled stoppages

highest availability, fault tolerant electronics with transient immunity and 3–2–0 or 3–2–1–0 voting

• Security for plant, product and people

fail-safe operation at all levels provides plant, product and personnel with the highest security

• Quality data

sequence of event and extensive diagnostics keep the operator informed

Highest Availability

The Triguard SC300E achieves the

highest possible TMR availability

(99.999%) by maximising the

Mean Time To Failure (MTTF) and

decreasing the Mean Time To Repair

(MTTR).

Modern low power integrated

technology allows the TMR

architecture to be cost effective for

an increasing range of high integrity

applications.

The ABB Triguard SC300E is the

evolution of 20 years of combined

vendor and customer experience

integrated into the design of the

ultimate TMR product. Building on a

proven platform, the Triguard SC300E

combines features that will maintain

excellence well into the future.

Today ABB is a global supplier with

key operating bases in North America,

Europe, Middle East and Asia Pacific.

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.

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.

New Ethernet based peer-to-peer communication

The System Controller Connect software provides a real time dedicated and secure interface

between Harmony/Symphony Plus systems and 800xA systems or Safety systems.

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
