Control Systems

Based on project needs, control system complexity can range from simple relays and contactors operated with a few push buttons to PLCs, data busses, drives, and servos operated via an expansive human machine interface (HMI) program on a desktop computer.”

Globe Life Field Retractable Roof

The Globe Life Field retractable roof is an example of a complex and feature-rich control system. It consists of an expansive distributed data bus, motor drives, remote I/O, and position sensors. The roof is controlled with a PLC and operated from a human machine interface (HMI) on a desktop computer.

State Farm Stadium Retractable Field

The State Farm Stadium field is an example of a mid-range complexity control system. The field is operated from an operator control station (OCS) that plugs into the leading edge of the field. The operator selects the direction of movement via the OCS and presses a push button to drive the field in and out of the stadium. The OCS controls and monitors remote I/O, displays status information, and enforces operation limitations.
