IS215UCVEH2A is a VME Controller Card designed by General Electric as a part of the Mark VI Series used in gas turbine control management systems. The UCVE is available in multiple forms, UCVEH2 and UCVEM01 to UCVEM10. The UCVEH2 is the standard controller. It is a single-slot board using a 300 MHz Intel Celeron processor with 16 MB of flash memory and 32 MB of DRAM. A single 10BaseT/100BaseTX (RJ-45) Ethernet port provides connectivity to the toolbox or to other control devices. The UCVEM modules have all the features of the UCVEH2, and can also support additional Ethernet ports, as well as Profibus, ISBus, or DLAN interfaces. Some UCVEM_ _ modules support secondary 10BaseT/100BaseTX Ethernet ports for use on a separate IP logical subnet. Configuration of the secondary Ethernet port is performed through the toolbox. The controller validates its toolbox configuration against the existing hardware each time the rack is powered up. A separate subnet address allows the controller to uniquely identify an Ethernet port.
