SURIS chose the PlantPAx® distributed control system from Rockwell Automation because it offered scalability, flexibility and easy integration of skids or third-party units. The solution was designed utilizing EtherNet/IP™ and included a complete and integrated information rich operator workstations (OWS) and engineering workstations (EWS) providing KPIs for better management decisions.
As a result, the system can easily integrate different terminal equipment, including the tank level measurement system, motor-driven valve network and starters, frequency converters, platform scales, energy monitors, load controllers in the truck loading stations, and other third-party systems.
An EtherNet/IP network was implemented, consisting of one Ethernet network at the physical level and several logic networks (VLAN) that provide the system with the best available level of accessibility, visibility and security, and helps ensure optimal communication performance through segmentation of the existing traffic. Stratix 8000™ modular managed ethernet switches were used and the network was segmented into three logic networks: one for I/O, a second one for TCP/IP communication and a third network to connect controllers and PASS visualization servers.
