Allessa Chemie improves plant monitoring with mobile SCADA 08 June 2012

Speciality chemicals manufacturer, Allessa Chemie has implemented SCHAD's Extend7000 Mobile SCADA system to get instant notification of critical power plant problems.

The company, which runs two production plants in the Rheinland area of Germany, selected the system for its Frankfurt-Fechenheim plant to improve the consistency of energy distribution monitoring within its 400V plant power supply.

Klaus Knahl, head of EMR operations at Allessa Chemie, who is responsible for instrumentation and control equipment, explains that changes to power distribution can cause losses in production, as well as compromising health and safety.
"We run a large continuous manufacturing operation 24/7 and needed to identify a way to improve the existing fixed monitoring capabilities," says Knahl.

"Extend7000 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."

Immediate notifications delivered directly to plant engineers through Extend7000 will, he says, help schad significantly and reduce downtime.

He also explains that the system has also been configured to trigger switching devices and monitor bus bars – both of which actions previously needed manual control room intervention.

Currently, SCHAD's 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.
