Hard and software engineering: S7 control systems have taken the place of S5 control systems in the central control system of the treatment plant, in the inlet protection structures and in the milk-of-lime system. Replaced were also precision mechanic components, communications between control systems, as well as all WINCC control stations. Switch cabinets All switch cabinets accommodating S 5 control units underwent modification to comply with the new requirements. Others: Optimization of several control algorithms, and modification of WinCC visualization systems. Implementation of a simulation system consisting of hardware and software components to check all functions before the above substitutions took place. Re-start of all system functions. |

In 2004, MATEC GmbH has expanded the existing process control system in the sewage treatment plant, and now it is intended to replace all old S5 control systems installed in 1998.
Such changeover can only be carried out without disrupting operations of the sewage treatment plant since the waste water from the industrial sources calls for continuous intake and purification. As lengthy downtimes of the plant would have disastrous consequences for the environment, a simulation of all functions prior to the changeover cannot be dispensed with.
