Totally Integrated Solution for Energy Center Control System for Tire Manufacturing Plant

Year: 2012

The customer was building a new tire manufacturing facility in central Iowa that was to produce agricultural tires with diameters of up to 110 inch. The manufacturing equipment required reliable utilities including steam, chilled water, nitrogen and vacuum systems. These systems made up their energy center that required automation systems. The customer had procured all equipment for the energy center including boilers, chillers, vacuum systems, pumps, valves and instrumentation. The customer had specified PROFIBUS-PA and DP as the interface between the field devices, VF drives and the PLC control system as a means to control the system efficiently.

WMENG was asked to design, supply and commission a Siemens based PLC/HMI control system to monitor and control the energy center.


The customers’ specification for PLC and HMI was Siemens so WME designed, supplied and installed multiple S7-151 safety PLC’s and HMI’s. The systems were connected via PROFINET and the field devices were connected via PROFIBUS-DP and PA networks.


The system provided the customer with an easy method of monitoring the systems that made up the Energy Center optimizing the operation and minimized downtime. Some of the systems control loops were complex and required extensive tuning and the system provided a means to efficiently tune these loops.
