The GE DS3815PTCC is a Terminal Controller Card for the GE Speedtronic Mark IV turbine control system, also designated as HCMA. This card is a crucial component of the system’s human-machine interface (HMI). It manages the communication and data processing between the core control modules and the operator’s display and input devices.
Function and Purpose
- Data Processing: The card receives raw data from the main processor (e.g., the DS3800HCDA) and other I/O modules. It then processes and formats this data for clear display on the HMI screen, such as a monitor or graphical display unit.
- User Interface: It allows the operator to send commands to the turbine control system. It translates user inputs from a keyboard or a mouse into a format the main processor can understand and act upon.
- Communication Bridge: The DS3815PTCC serves as a vital bridge between the core control logic and the operator interface. By handling all HMI communication, it offloads the main processor, allowing it to focus exclusively on critical, real-time control functions.
Related Components
- HMHA (Human Machine Interface) Boards: The DS3815PTCC works directly with other HMHA boards to manage display and input functions.
- Processor Cards: The card communicates with the main processor to exchange data and commands.
- Backplane Cards: It plugs into the system’s backplane, like the DS3800XCIB, which provides it with power and a data bus to communicate with other modules.
