We at Industrial Systems have worked with Great Western Malting on various projects for over 20 years. We were honored when GWM contacted us to assist them with the design and construction of a new malting facility at their Pocatello Idaho site. This was a fast track project that was to be in production within 18 months of our intimal involvement and concrete was already being poured by the time we began work. Our design efforts focused on staying ahead of the contractors and the concrete for many months before we could change our focus final control system design and programming. We designed a multi level fiber network to ring this site and provide separate physical network layers for SCADA, peer to peer and PLC I/O and VFD com needs. All motor driven equipment in this facility including pumps fans and conveyors are equipped with VFDs to provide maximum flexibility in production. The control system backbone was the latest 1 GB Ethernet capable PLC processor from Allen-Bradley. This single processor controls 100 VFDs and nearly 2000 I/O points all over Ethernet IP.
