The core of the CS7X system is an event driven database designed for autonomous local control. The CS7X system architecture is based on a 32-bit CPU, named Phoebus Control Module (PCM), and a highly reliable, redundant serial bus utilizing controller area network (CAN) technology. The system utilizes state-of-the-art web technology for human machine interface (HMI), local/remote control, maintenance and routing.

Supported applications include valve and motor control, AGA3/AGA8 gas flow calculations, continuous loop PID control, and emergency shutdown capabilities. Redundant processors, hot-swappable components, global database architecture and multiple communication channels achieve high availability of the unit. I/O modules are available in either a 6U rack or DIN rail mount configuration. It can be implemented with one or two PCM(s) in a hot-standby configuration.

The CS7X system can be configured to provide redundancy at the PCM, power supply, and I/O (control) level for applications that require high levels of system reliability. The CS7X system architecture permits redundancy to be implemented for each segregated process node allowing critical processes to be redundant. Non-critical processes can use the unit in a non-redundant mode to optimize overall system costs.
