SPECIFICATIONS

Part Number: IS215UCVEM08A
Manufacturer: General Electric
Country of Manufacture: United States(USA)
Series: LCI
Product Type: US2000 Processor Board

Functional Description

IS215UCVEM08A is a US2000 Processor Board developed by General Electric. It is an Ethernet connection circuit board. The device's front is equipped with a number of ports for UCVEM08. These ports are used to connect Ethernet cables and COM ports. Male connections on the component's back are utilized to connect this circuit board with the system. The component slides into position. On the circuit board, there are additional attaching points as well. The UCVEM08 uses a variety of parts, including, among others, an SD card, diodes, resistors, integrated circuits, condensers, and a battery.

Physical Design and Connectivity

• Front Panel Connections: The front side includes multiple ports dedicated to networking and communication. These consist of Ethernet ports for high-speed network interfacing and COM ports for serial communication. These interfaces allow the processor board to connect with other control modules, operator stations, and external devices.
• Rear Connectors: The back of the processor board features male connectors designed to plug directly into the system backplane. This ensures secure, reliable signal transfer between the UCVEM08A and the rest of the control rack. The module slides into a designated card slot and locks into place, maintaining mechanical stability even in vibration-prone industrial environments.
  • Internal Components: The board is built with a range of electronic components that support processing, memory, storage, and communication. 
  • SD card slot for storage and firmware
  • Diodes, resistors, and capacitors for signal conditioning and protection
  • Integrated circuits (ICs) for processing and logic functions
  • Battery for maintaining NVRAM data
  • Connectors and fastening points for secure installation

Key Features

Enhanced Communication Support: Includes all features found in the UCVEH2 models, with the addition of

• Profibus capability
• Additional Ethernet ports for extended networking flexibility

These enhancements enable the module to integrate seamlessly into larger and more complex industrial networks.

Multiple Ethernet Subnets: The UCVEM-series modules support secondary 10BaseT/100BaseTX Ethernet ports, which can be assigned to a separate logical subnet. This is particularly beneficial for applications requiring

• Isolated control networks
• Dedicated communication paths
• Segregated data streams for safety or redundancy

Configuration of the secondary Ethernet port is managed through the Toolbox software, ensuring precise network setup. Each time the controller powers on, it verifies the Toolbox configuration to ensure it matches the installed hardware, improving system consistency and reducing configuration errors.

Subnet-Specific Identification: Each Ethernet port can be uniquely identified using a different subnet address, allowing the controller to route communication properly and maintain organized network segmentation.

Technical Characteristics

• Processor: Intel Celeron 300 MHz - This provides sufficient processing capability for real-time turbine control and plant automation tasks.
• Memory: 32 MB DRAM for runtime operations. 16 or 128 MB Compact Flash module for storage. 128 KB L2 cache for faster data access. 8 KB battery-backed SRAM (NVRAM) for critical controller data retention
• Operating System: Runs on QNX, a real-time operating system known for its stability, determinism, and reliability in mission-critical control applications.

Communication Ports

COM1

• Reserved for diagnostics
• 9600 baud, 8 data bits, no parity, 1 stop bit
• Primarily used for troubleshooting and maintenance

COM2

• Supports serial Modbus communication
• Configurable baud rate: 9600 or 19200
• Used for linking external Modbus-enabled devices

Power Requirements

It requires multiple voltage inputs for stable operation:

• +5 V DC: 6 A typical, 8 A maximum
• +12 V DC: 180 mA typical, 250 mA maximum
• –12 V DC: 180 mA typical, 250 mA maximum

These requirements ensure that the board receives sufficient power for both processing and communication functions.

Programming and Control Logic

The processor board uses a control programming language based on Relay Ladder Diagram (RLD) logic. This structure combines Boolean logic with analog and discrete control blocks, enabling flexible and detailed control strategies. Supported data types include:

• Boolean
• 16-bit signed integer
• 32-bit signed integer
• 32-bit floating point
• 64-bit long floating point

This wide range of data formats supports high accuracy and robust control functionality in industrial applications.
