Functional Description

IS220UCSAH1A, REV K is a revision Controller Module developed by GE. It is a part of Mark VI control system. This module is crucial in real-time control, ensuring high-speed data processing and communication between different system components. The controller is designed for panel mounting and establishes communication with I/O packs through its on-board I/O network interfaces. It serves as a central processing unit within the Mark VI system, efficiently handling input/output operations and executing application code.

Operating System

Operates on the QNX Neutrino OS, a real-time, multitasking operating system specifically designed for high-speed, high-reliability industrial applications. The use of QNX ensures:

• Deterministic real-time performance
• Robust multitasking capabilities
• Minimal system downtime
• Efficient resource management

Processor and Network Connectivity

This controller module is powered by a 667 MHz Power QUICC II Pro Freescale processor, which provides the computational power necessary for demanding industrial applications. It features multiple Ethernet ports to facilitate seamless communication within the system:

• Two 10/100BaseTX Ethernet ports for connection to the UDH (Unit Data Highway)
• Three additional 10/100BaseTX Ethernet ports for connectivity to IONets (I/O Networks)
• These high-speed communication interfaces enable reliable data exchange and real-time system monitoring.

Power Supply

The module is designed to efficiently manage its power requirements:

• Operates on an incoming 28 V DC power supply
• Converts 28 V DC to 5 V DC for internal operation
• 5 V DC is used to derive all other internal power planes
• This power management system ensures stable operation and consistent voltage regulation for optimal performance.

LED Indicators and Diagnostics

The UCSA module is equipped with multiple LED indicators, each providing real-time status updates on different system parameters:

Communication Status LEDs

• Link (Solid Green) – Indicates that the Ethernet PHY has successfully established a link with an Ethernet switch port.
• Act (Solid/Flashing Green) – Represents packet traffic on an Ethernet interface. It blinks when traffic is low but remains solid green in most cases.

Power and Boot Indicators

• Power (Solid Green) – Confirms that the internal 5 V supply is up and regulating.
• Boot (Red/Blinking Red) – Displays boot progress and errors using a blinking pattern. Boot blink codes help in troubleshooting startup issues.

Operational Indicators

• Online (Solid Green) – The controller is operational and running application code.
• Flash (Blinking Amber) – Indicates active access to any flash memory device.
• Dc (Solid Green) – Denotes that the controller is the designated controller in the system.

Diagnostic and USB Status

• Diag (Solid Red) – Indicates that the controller has detected a diagnostic issue. The ToolboxST application can be used to view and clear these diagnostics.
• On (Solid Green) – Confirms that the USB interface is active and functioning correctly.

Frequently Asked Questions

What is IS220UCSAH1A, REV K?
It is a Controller Module developed by GE under the Mark VI series.

What programming methods does the controller support?
The controller can run rungs (ladder logic) or blocks (function block diagrams), allowing flexible control logic implementation based on the application requirements.

How does the controller achieve time synchronization?
The IEEE 1588 protocol is used through the R, S, and T IONets to synchronize the clock of the I/O packs and controllers to within 100 microseconds, ensuring precise coordination of system operations.

How does the controller handle external data transfer?
External data is exchanged with the control system database in the controller via the R, S, and T IONets, ensuring reliable communication between system components.

What is the role of the controller in a simplex system?
In a simplex system, the controller manages Process inputs/outputs to the I/O packs.
