Product Overview

The IS220UCSAH1A-C is listed as a variant of GE’s UCSA controller for the Mark VIe control platform. A UCSA controller runs application code and communicates with distributed I/O packs over dedicated IONet connections. Separate Ethernet interfaces carry controller data and communications with engineering and operator systems.The documented UCSA platform uses a 667 MHz Freescale PowerQUICC II Pro processor, 256 MB DDR SDRAM and the QNX Neutrino real-time operating system. It is used in turbine and balance-of-plant control arrangements where controller processing, I/O communication and system-status visibility are required.

Frequently Asked Questions

1. What role does the UCSA controller perform in a Mark VIe system?
It runs the control application and exchanges data with distributed I/O packs through IONet.
2. Does the controller contain the application I/O channels?
No. In GE’s UCSA architecture, the controller communicates with separate I/O packs rather than hosting application I/O on a backplane.
3. How are its Ethernet interfaces divided?
The documented UCSA specification lists two primary Ethernet interfaces and three IONet interfaces. The IONet ports communicate with controllers and I/O modules.
