SAIMC: Johannesburg branch

October 2019 SAIMC

The August technology evening we was hosted by Yokogawa at the Bryanston Sports Club. The theme was to find out more about the difference between a PLC and a DCS, where the PLC came from, some PLC theory, why we use both, and some of the components of these systems.

In bygone years all manufacturing processes were manual, people filling, labelling and packaging. General Motors Corporation decided they needed an automated system which could be easily programmed, easily maintained and reused in future applications. Initially PLCs were used for digital control like conveyor belts, on-off control, timers, counters etc. Now, applications for PLCs include energy management in buildings, steel making, breweries, food and beverage and countless others – but why then a DCS?

A DCS is generally a software platform for everything with enhanced databases, PID control, graphics and tags. A PLC system generally works from the field devices to a controller running on one network, the DCS can bring numerous controllers and networks together and distribute this information to engineering, HMIs, all the way up to business integration control.

We were taken through the questions you need to ask yourself before deciding on a PLC or DCS. Questions like: Will you be doing simple or complex control? What is the value of product manufactured and the cost of downtime? What does the operator need to be successful?

All this led to some lively debate and discussions of actual examples that individuals had experienced in their plants.

Ladies Tea

The Ladies Tea was held on the 23 August to celebrate woman’s month. What a privilege to spend some quality time in the open air with the ladies of our industry.

Caroline Carter (marketing & customer relations manager) outdid herself with a unique outlook on ‘Women as the Instruments of Measurement and Control’. She gave wonderful insight on how as the measures of control, women now influence business decisions in a traditionally male dominated industry.

SAIMC president Annemarie van Coller also addressed us with words of encouragement. It is so very important in the world we live in to motivate, encourage and support one another.

The day was a huge success and will be repeated in 2020. The branch thanks everyone for their attendance and support.
