RCI’s Secure Segmented Control and Monitoring System
The SSCMS is a scalable, fault tolerant, field programmable gate array (FPGA) based control system which enables data configuration control of all system control logic from a single set of triple modular redundant data configuration control servers, regardless of the number of independent facility units and/or independent control segments for each unit. All control logic is implemented within the FPGA, and as such, there is no executable software within the runtime environment. The platform consists of the chassis and a system of modules that are interchangeable between chassis, and multiple chassis can be connected to achieve scalability as needed.
The SSCMS architecture consists of two levels of segmentation for communication and control algorithms, which execute on distributed FPGA hardware cores. The first layer of segmentation is referred to as the “System Manager” layer and is intended to correspond to the major functional modules or operational units of a multi-unit plant or facility. The System Manager’s primary function is to communicate to the second layer of segmentation, referred to as the “Segment Manager” layer, which further segregates the input/output and control functions to ensure functional independence within a major plant functional unit.
The System Manager portion of the architecture acts as a gateway to the plant or facility’s main operational human system interface (HSI) and does not depend on the specific platform or architecture of the connected HSI or data configuration control set of equipment. The redundant HSI and data configuration control servers and redundant connected networks are not required for the distributed FPGA control architecture to perform its control function. This architecture allows for multiple sets of equipment to be used to configure, send output to and receive input from each of the control system FPGAs throughout the architecture. The System Manager supports industry standard communication protocols to communicate with the plant supervisory network.
