Designed to function as a plant Distributed Control System node, the Vertex can interface with the plant’s DCS via hardwired input/output signals or serial or Ethernet communications. The Vertex control uses SNTP (synchronized network time protocol) over Ethernet to allow users to synchronize the control’s real-time clock to the plant distributed control system.
With the capability to monitor and control all compressor based functions (i.e., bearing temperatures, vibration levels, control oil levels, etc.) the Vertex controller is also a cost-effective compressor control/protection device as well as a plant DCS monitoring node.

As a replacement for old or obsolete anti-surge controllers, the Vertex can be configured to function like these controllers but with two-times faster scan rates, improved surge anticipation logic, and one integrated package for all control functions (anti-surge control loop 1, anti-surge control loop 2, performance control, and dual-redundant control).
