Functional Features:
- Standalone controller executing application code independent of a backplane
- Communicates with I/O packs via IONet (private dedicated Ethernet)
- Supports CIMPLICITY graphic HMI interface for heavy turbine management
- Up to three modules can be mounted side-by-side for compact triple-redundant (TMR) configurations
- Natural convection cooling through three-side grille openings; no onboard fan or battery required
- Front-panel Ethernet jacks interface with other MKVI, MKVIe, or EX2100 excitation controllers, maintenance stations, and operator stations
Application Scenarios:
- Gas turbine control and protection systems in power plants
- Steam turbine speed and load control
- EX2100 excitation control integration
- Plant balance-of-process control and retrofit applications
Performance Parameters:
- 667 MHz processor provides sufficient throughput for standard turbine control algorithms
- QNX RTOS ensures deterministic, low-latency task execution
- 256 MB SDRAM and 1 GB CompactFlash support substantial application programs and configuration data
- Fanless operation enhances reliability and reduces maintenance
Material and Structural Characteristics:
- Single boxed assembly with front communication panel
- Two screw mounts on the rear edge for base mounting in cabinets
- Three-side grille openings for natural airflow
- Industrial-grade metal housing with EMI shielding
- Front panel with six Ethernet jacks, USB port, and LED indicators
Working Principle: The controller executes user application code stored in CompactFlash under the QNX Neutrino RTOS. It exchanges data with distributed I/O packs over the IONet Ethernet network, processes control algorithms, and issues commands to field devices. The controller also interfaces with HMIs, historians, and peer controllers via Ethernet connections on the front panel. Installation Requirements:
- Mount on a base plate inside a control cabinet using the two rear screw mounts
- Ensure grille openings remain unobstructed for natural convection cooling
- Connect 18–36 V DC power supply
- Wire Ethernet connections from the six front-panel jacks to IONet, UDH, and peer networks
- Configure the controller using ToolboxST application software
- For TMR systems, install up to three modules side-by-side
Usage Notes:
- Confirm firmware compatibility with the Mark VIe system version before deployment
- Avoid blocking the three-side ventilation grilles during installation
- Use the LED indicators (Power, Boot, Online, Flash, DC, Diag) for rapid fault diagnosis
- The controller is not suited for the most demanding model-based control applications; consider UCSC or UCSCH controllers for those scenarios
- Follow ESD precautions when handling the module
