Mark* VIe control
The Mark* VIe control was designed to serve a wide variety of control and protection applications from steam and gas turbines to power generation balance of plant (BOP) equipment. The control provides more options for redundancy, better maintainability, and greater capability for locating I/O closer to the controlled equipment.
The control system consists of three primary components, the controllers, I/O networks, and I/O modules as shown in diagram.
The Mark VIe controller is a single board, which run the application code. The controller communicates with the I/O packs through onboard I/O network interfaces.The controller operating system (OS) is QNX® Neutrino®, a real time, multitaskingOS designed for high-speed, high reliability industrial applications.
Unlike traditional controllers where I/O is on a backplane, the Mark VIe controllerdoes not normally host any application I/O. Also, all I/O networks are attached to each controller providing them with all redundant input data. This hardware architecture along with the software architecture guarantees that no single point of application input will be lost if a controller is powered down for maintenance or repair.
The controllers are designated as R, S, and T in a TMR system, R and S in a dual system and R in a single system. Each controller owns one I/O network (IONet). The R controller sends outputs to an I/O module through the R IONet, the S controller sends outputs through the S IONet, and the T controller sends outputs through the T IONet.
