Some of Our Projects |

Process Dynamics was contracted to design, supply and implementation this fully redundant Automation System for the Gas Turbine fuel supply system. Two systems were installed at Atlantis and another two systems in Mosselbay. The system was designed using SIEMENS S7—400 H redundant PLC system and redundant Profibus Networks to guarantee 99.9% availability.
All instrumentation was installed on a redundant Profibus Network and operation is done via 2 SIEMENS Panel PC’s and a central WinCC SCADA system for event logging and historical data collection.

Process Dynamics was contracted to replace all SIEMENS S5 PLC equipment with the new generation SIEMENS S7 PLC’s at Matimba Power Station in Ellisras.
The Ash stacker, Ash Spreader and Dust Handling Plants 1 to 6 were all controlled by old SIEMENS S5 PLC’s. Due to the discontinuation of the S5 PLC Range all systems had to be replaced with newer generation equipment to ensure availability of spare parts and continued support.
Process Dynamics replaced and reprogrammed all the S5 PLC’s (Around 9500 IO) as part of an exercise to upgrade the power station. Apart from the upgrades a new OPCR interface and SCADA system was also installed making use of wireless technology to gather data from the outside plant.
