Chemical manufacturer is first to implement new mobile SCADA solution

With the aim of ensuring consistent energy distribution around the clock, the engineering mobility specialist SCHAD has announced the implementation of its EXTEND7000 Mobile SCADA solution at the international speciality chemicals manufacturer, Allessa Chemie.
The company, which runs two production plants in the Rheinland area of Germany, selected the mobile solution for its Frankfurt-Fechenheim manufacturing operation. The solution was purchased in order to more effectively monitor the consistency of energy distribution levels within its main 400V plant power supply.
The ability to have immediate notifications delivered directly into the hands of plant engineers offers important benefits, including reduced downtime. In addition, the system has been configured to trigger the use of switching devices and to observe the value of individual bus bars, both of which previously needed to be activated via the company’s control room, causing delays to production schedules.
Currently, the mobile SCADA solution has been configured to monitor 540 parameters - 400 switch positions and 150 alarms - which are recorded and controlled by a Siemens Simatic S7-400 controller using PCS7 and monitored by its existing WinCC SCADA system from a fixed control room.
Klaus Knahl, head of EMR operations at the chemical company said of the system: 'We are running a large continuous manufacturing operation 24/7 and needed to identify a way to improve the existing fixed monitoring capabilities.' He added: “(The new system) was the perfect solution and allowed us to continue using our existing SCADA system and simply enhance it to suit a more mobile way of working.'
