Central units with extensions

The 40 and 50 series. It’s possible to increase the number of inputs / outputs of the basic

central unit by adding up to 6 local extension units of either type, binary or analog (Figure 1-1).

2.2. Central units with CS 31 bus

The 50 and 90 series. It’s possible to increase the number of inputs / outputs of the basic

central unit by adding remote units. The central unit controlling the system is called the

MASTER central unit. The maximum bus length is 500 m without an amplifier and 2000 m with

3 amplifiers (1 NCB or NCBR unit enables bus amplification for 500 m).

The master central unit can manage up to 31 connection points called SLAVES, such as:

– A remote unit with extension possibilities: a maximum of 6 extension units comprising of a

maximum of 8 analog input channels and 8 analog output channels

– A simple remote unit (without extension) with analog or binary inputs / outputs

– A remote TCAD display

– An ABB NCSA-01 variable speed drive interface

– A high speed counter unit

– A central unit (50 series with extension possibilities, 90 series and the previous 30 series)

– Or any other device which disposes of a CS 31 communication (see Figure 1-2).

General setup rules

An ABB AC 31 system always includes an AC 31 central unit. There are three types of central units:

– The 40 series central unit, with a local inputs / outputs extensions interface

– The 50 series central unit, with a local inputs / outputs extensions interface

and a CS 31 bus interface

– The 90 series central unit, with a CS 31 bus interface

Each central unit incorporates a specific number of binary inputs / outputs and occasionally

analog. It is possible, depending on the central unit, to increase the number of inputs / outputs,

to add input / output extensions connected directly to the central units or remote input / output

units via the CS 31 twisted pair.

The interruptions have priority over the main program execution. If all three interruptions are

triggered simultaneously then the interruption triggered by I 62.03 has priority over the I 62.02

input interruption which in turn has priority over the cyclic interruption. Once an interruption has

been launched it cannot be interrupted by another (Figure 1-5).

The execution duration of a cycle (bus cycle + program cycle) is controlled by the central unit.

Any excess of the cycle time defined by the user in AC31GRAF is signaled by the ERR Led, at

the front of the central unit, as of the first program cycle.

Support

The range of support provides for the following:

· Delivery of spare equipment

· Repairing of faulty units and systems

Applications Department

Our modular programmable control system Advant Controller 31 provides you with a wide range of high-performance modules and standard software to master all your applications.

The applications department helps you select the appropriate system for solving your particular tasks. We are

also in a position to develop your special user- or problem-oriented user program.

In this way you can make use of ABB’s know-how in the

field of ’factory automation’.

In particular the applications department offers:

· Cooperation during specification of control tasks and

defining of the most suitable system configuration

· Developing of user programs such as PLC instruction

lists or sequential function charts for the Advant Controller 31 system

· Commissioning

Precondition for this is that a time schedule is agreed and

progress of work supervised continuously by a project

engineer to be appointed by the user

AC31 project planning seminars

Project planning, programming and commissioning of

model plants. Principles of networking and the data

exchange via serial interfaces (process control). Practical training at the automation systems.

Maintenance Service and Support

Maintenance Service

We operate a qualified service department, so we can help you to solve even difficult problems.

· Advice by telephone (Help line)

· Trouble shooting and fault recovery of the machine and plant

· Support in case of program development

· Training of the personnel in the factory

· Renting of programming tools

In case of service support we ask you to do the according

preparations depending on the desired service e. g.:

· Making available the complete documentation

· Free access to the machine/plant

· Assignment of operating personnel etc.

However, Automation Sentinel’s subscription program goes

much further to target the installed base of classic 1180M, 1190,

and Nexus solutions to provide an affordable way to upgrade

software to gain productivity benefits from the latest System

800xA solution. ABB upgrade programs go beyond rip and

replace solely for obsolescence in an effort to reuse as much of

the existing equipment as possible. ABB addresses customer’s

business critical needs to bring value and increased capabilities

that truly increase customer ROI and solve problems. Let’s review

typical classic QCS system upgrades in greater detail.

AccuRay 1180M and 1190 Upgrades

For AccuRay 1180M and 1190 QCS systems, the Automation

Sentinel subscription program cost effectively maps existing

software over to the latest QCS800xA software. Expansion

software not available in these classic systems is available to

address business critical needs. With older 1180M and 1190

QCS systems there are often hardware obsolescence issues that

need to be addressed. A site survey by ABB engineers is a first

step to determine the lifecycle status of key QCS subsystems

and identify support and failure risks. Modular hardware upgrades

are available such as Measurement Platform to Network Platform

upgrades and the rebuild of the front-end electronics of Profiler

subsystems. By moving scanners and profilers to the latest

QCS800xA architecture users can upgrade to QC Aspect

Workplaces. Both scanning platform and profilers subsystem

upgrades are designed to reuse much of the existing hardware

to leverage previous equipment investments.

The current technology environment creates both challenges and

opportunities to users when it comes to maintaining a modern

Quality Control System. The challenge for users is to ensure that

new PC-based software is kept up-to-date to maintain security

and performance levels. The opportunity for users with older

classic QCS systems is to extend support for their existing

control software investment, while establishing an affordable path

to the next generation of functionality. ABB QCS800xA Quality

Control solution built on the System 800xA platform is representative of this technology shift.

The need for automation suppliers

to provide an active lifecycle management program is clear.

Automation Sentinel is ABB’s program designed to address

lifecycle management needs and provide the best overall ROI for

your past, present and future software investments and ensures

PC software is kept current for the latest QCS800xA solution.

Protect the value of ABB classic Quality Control Systems with lifecycle migration

to the latest QCS800xA solution.

Technology Trends

Technology is changing our behavior at a fast pace. A large part

of today’s modern process automation system now consists of

server-client technology, inherited from the office automation

(IT) world. With the introduction of open standards for operating

systems and standard PC hardware and software, a new

challenge was introduced to process automation system owners.

In the past there was a level of protection from frequent software

updates and constantly increasing connectivity requirements,

now these parameters are in a constant state of flux. The

industry has embraced this technology as process automation

supplier’s shift from proprietary hardware and software to

custom-off-the-shelf (COTS).

Accuray Systems

AccuRay designed, manufactured and marketed computer-based automation and management

information systems for manufacturing processes to save raw materials and energy,

increase productivity, lower costs and improve product quality. AccuRay automation systems

controlled manufacturing processes in the pulp and paper, rubber, plastics, textile and metals industries.

AccuRay systems measured the basic properties of materials, such as weight, moisture, thickness, width, opacity and component content.

The technologies for performing such measurements employed a variety of physical and electronic principles that included nuclear,

X-ray, infrared, radio frequency, optical, pneumatic and electromagnetic techniques.

AccuRay technology and expertise has helped ABB maintain its status as the leading provider

of measurement and control technologies for the Pulp and Paper industries.
