UCSC 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/O network (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.
The following table provides the specifications for the UCSC controllers. For more information on the UCSC controller, refer to “UCSC Controllers” in the document Mark VIeS Functional Safety Systems for General Market Volume II: System Guide for General-purpose Applications (GEH-6855_Vol_II
