   a. Secure Reporting, In-house and External Contact Management - Internet-based.

All businesses with regional and international branches require an 'Intranet' for staff to be able to communicate with the same facility as if working within the same building. The larger the business, the greater the need, yet the greater the difficulty. In the first place, there is the need to maintain confidentiality. Secondly, the need to structure the communications into standardised formats, so that information can be made available to the colleagues who require it, but avoids overloading staff so that they get lost in 'Data Smog'. It is also essential that the information flow can identify and classify the business data generated in the Corporation, and automatically update the ERP, Accounting and Administration's records.

Swystem Logic is fortunate in having such Partners as Logic Solutions Inc., of Ann Arbor, MI - USA, who have provided such software to world-renowned Corporations: General Motors, Ford, Mitsubishi among them. The standard, customizable off-the-shelf components of this software include: Logic Ensemble and Logic Intranet2000. Thanks to their wide application and distribution, they are cost effective solutions, known for their reliablity and security.

    b. Production Information Manager  - integration with ERP systems.

We know that many smaller manufacturers view the costs of installing physical engineering and hardware, engineering, sensors and actuators as prohibitively expensive.

As a result, we have developed a software package which performs as an industrial SCADA,  but is a variant which depends on the operator's input at a keypad for it's inputs, instead of having them transmitted automatically from sensors, via PLC Controllers and an industrial network. In this way, the cost of the installation can be reduced to between 10% to 25% of the usual level of investment in the fully equipped and installed industrial PLC-SCADA Control System.

While the lower level of investment provides a lower level of control compared with fully-fledged hardware-based PLC-SCADA Control, it does provide a high level of 'overview' of the manufacturing process. Recipes can be followed, while the operator inputs actual, observed values relating to process conditions. These values are then compared with the values specified in the original Recipe. Trends can therefore be derived, and process history stored in the data-base. Even a Plant 'Visualization' (on-screen 'mimic diagram' ) can be shown. But the constraints of manual input must be recognised, and the reliability of the human operator have to be taken into account.

Nevertheless, the fact that a conventional, manual operation can afford to take the first steps towards modern computer-aided manufacture at a very economic price, has to be a considerable step forward for manufacturing industry. The additional fact is that the basic network is  upgradeable. It allows the backbone to accept PLC-controllers with sensors, actuators and other hard-wired components to be grafted onto the system. It therefore allows the system to grow as the business develops and the finances permit.

   c.  SCADA - Supervisory Control And Data Acquisition - Please follow the Link

SCADA is the revolution which arrived on the scene just over a decade ago. Industries were getting automated, with individual machines or groups of equipment having their routine movements and actions started and stopped by programs running on computers. The need for reliability, led to the development of simplified programmable controllers, PLCs, which could resolve simple programs, and send appropriate signals to actuators at the right moment in time. The accent was on simplicity, but above all, on reliability. Nothing else was good enough for mission critical operations which controlled power stations, transport systems or medical applications.

SCADA provides the manufacturer with the means of integrating all the equipment in the plant with an industrial network, which has an industrial PC-server. This gives Management an overview of the production in real-time, which was never before possible without SCADA. Management now has data about productivity, breakdowns, machine maintenance reminders, the trends of production parameters (temperature, pH, times, pressures, volumes, number of pieces, areas, thicknesses) all instantly available. Management can instantly correlate observations of a running process with historical data about previous productions one month, one year or a decade ago.

Not only this, SCADA presents an active 'mimic diagram' of the plant, a 'Visualization' where Production Management, Technicians and Operators can view the entire Plant, or progressively focus in on individual machines, work stations or groups of equipment. Instead of a time-consuming walk through a section of the Plant, the responsible Operator or Manager can actually 'see' on-screen whether all processes and equipment are performing within specified tolerances. Of course, this is not an on-screen simulation or artificial sequence of video images - every image is a response to a signal, a response from a sensor or a device which has been actuated. [This does absolve the Technician or Production Manager from committing shoe-leather to 'walking the floor', experiencing the tempo of production and getting the verbal reports of Operators. But it gives Management more time to do just that - avoiding unnecessary detective work, checking conflicting reports to determine the true reasons of the cause of non-conformances or defective equipment.]

But the great advantage to Production and Technical Management is that SCADA reports the facts, and has the ability to replay history. It can turn the clock back to a time when a non-conformance occurred. Then the particular situation which occurred can be studied: the status of the particular equipment can be seen on the Visualization, the process parameters logged at that time noted, and their trends studied on the Graphs of each attribute logged. This obviously has great significance for trouble-shooting, for 'Kaizen' - continuous improvement and fine-tuning of processes.

And of course, SCADA has great significance for Quality Assurance such as ISO9000 and the different QA schemes of each major automobile manufacturer.
