General Electric IS420UCSCS2A Mark VIeS Safety Controller

The Mark* VIe and Mark VIeS Functional Safety UCSC controller is a compact, stand-alone controller that runs application-specific control system logic. It can be used in a diverse range of applications, from small industrial controllers to large combined-cycle power plants. The UCSC controller is a base-mounted module, with no batteries, no fans, and no hardware configuration jumpers. All configuration is done through software settings that can be conveniently modified and downloaded using the Mark controls platform software configuration application, ToolboxST*, running on a Microsoft & Windows & operating system. The UCSC controller communicates with I/O modules (Mark VIe and Mark VIeS I/O packs)through on-board I/Onetwork (IONet) interfaces.

The Mark VIeS Safety controller, IS420UCSCS2A, is a dual core controller that runs the Mark VIeS Safety control applications used for functional safety loops to achieve SIL 2 and SIL 3 capabilities. The Mark VIeS Safety product is used by operators that are knowledgeable in safety-instrumented system (SIS) applications to reduce risk in safety functions. The UCSCS2A controller can be configured for Simplex, Dual, and TMR redundancy.

The non-safety Mark VIe controller, IS420UCSCH1B, can be interfaced with the Safety control system (through EGD protocol on UDH Ethernet port) as a controller for non-SIF loops or as a simple communication gateway to provide data with OPC UA Server or

Modbus Master feedback signals, if needed by the application.

Ethernet Ports/Controller Communications Support;3 IONet ports (R/S/T) for I/O module communications (simplex,dual, and TMR supported); ENET 1 - EGD/UDHcommunications to ToolboxST PC, HMIs, UCSCH1B Gateway controller, and GE PACSystems products; Modbus TCP Slave, Read-only; Supports Black Channel communication between other Mark VIeS Safety controllers.

Application

A typical application for the GE Mark VIeS in a power plant might involve using the system to monitor critical parameters of a gas turbine. The system could control the turbine’s start/stop cycles, monitor fuel flow, pressure, and temperature, and activate emergency shutdown sequences in the event of abnormal conditions to prevent damage or catastrophic failures.
