ABB Freelance 800F AC800F Control systems

AC 800F opens up the flexibility of Fieldbus

technology to the user. The AC 800F collects

and processes diagnostic and process data

from four Fieldbus lines, which may be of different

types. It does this in addition to the

tasks of a “conventional” process station.

The AC 800F is available in two versions:

• 4 MB static RAM, 4 MB EPROM

• 16 MB synchronous dynamic RAM,

8 MB EPROM

Up to 4 (different) fieldbus modules can be

plugged into the AC 800F. The communication

with other controllers runs via Ethernet.

The AC 800F optionally provides several levels

of redundancy:

• device redundancy with 2 AC 800F

• power supply redundancy (24 V DC)

• Ethernet communication redundancy

(standard)

• Cable redundancy for Profibus DP,

requires external equipment (RLM01)

The data protection is made via battery back-up

by Ethernet or battery modules with appropriate

functionality.

• Process Station with integrated fieldbus

capability

• 4 high-speed fieldbus lines

• Supports different fieldbus types, even

simultaneously:

PROFIBUS-DP, up to 12 MBd

Modbus

CAN

Foundation Fieldbus H1 (with LD800

HSE)

• Easy engineering:

fully integrated in Control Builder F

• One unified database for field devices

shared by the control level and the Human

System Interface (HSI)

• Module recognition with factory and operational

parameters

• Comprehensive diagnostics for proactive

maintenance

• Compact, rugged design

• Front panel connectors

• DIN Rail (C-rail) or wall mounting for easy

installation

• Ambient temperature 0-60 °C (32-140 °F)

with temperature monitoring

• EMC certification according to EN50082

• Certification:

CE, NAMUR, CSA, UL, EN61000-6-2.

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two

AC 800F. To ensure quick and smooth takeover by the secondary

AC 800F in case the primary AC 800F fails, a dedicated

redundancy communications link through the second Ethernet

module makes sure that both AC 800F are always synchronized.

All inputs and outputs are designed to support redundant

operation.

Profibus Line Redundancy

Using the Redundancy Link Module RLM 01 will do the conversion

of one simple, non-redundant Profibus line into two reciprocally

redundant lines.

You can position the Redundancy Link Module RLM 01 directly

after a Profibus module (master), before a bus segment with

several slaves or before an individual slave. PROFIBUS stations

with redundant couplers can be directly connected to the

PROFIBUS set redundant by RLM 01. Stations with only one interface

can be optionally assigned to the one or other line.

For technical description dates of the Redundancy Link Module

RLM 01 see document 3BDD011600R0201.

An alternative solution to the Profibus line redundancy is to use

a Fiber Optic Ring, for example with the OZD Profi 12M module

from firm Hirschmann

AC800F Redundancy together with Profibus Line Redundancy

You can achieve both; controller redundancy and Profibus line

redundancy by using two AC 800F with one RLM01 each. This

topology combines the advantages of controller redundancy

with the one of line redundancy as described in the above

paragraphs
