Functional Description

DS200TCDAG1BCB is a Digital I/O Board developed by GE. It is a part of the Mark V control system. The Digital I/O Board (TCDA), located in the digital I/O cores Q11 and Q51, is a component for processing digital contact input and output signals within the system. The ability to process and transmit digital signals effectively makes it an integral part of the control system. By ensuring accurate and reliable signal handling, it contributes to the overall efficiency and responsiveness of the system. This is particularly crucial in industrial settings, where precise control and monitoring of equipment are essential for safe and efficient operations.

Features

• Input Signal Processing: The board handles the digital contact input signals received from the DTBA and DTBB terminal boards. These signals typically originate from various sensors, switches, or other digital input devices within the system. By accurately processing these inputs, the TCDA ensures that the system can correctly interpret and respond to the status or changes in connected devices.
• Output Signal Processing: In addition to input processing, it manages contact output signals, which are used to control relay and solenoid actuators. These signals are sent from the TCDA to the two boards. Relays and solenoids are critical components in many industrial applications, as they facilitate the activation or deactivation of circuits and mechanical systems.
• Signal Transmission: Once processed, the signals are transmitted over the IONET, a high-speed communication network within the control system. The IONET ensures rapid and reliable transmission of data between various components. Specifically, the processed signals from the TCDA board are sent to the TCQC board located in R1 and the CTBA terminal board in R5.

Connectors

• JP connector is responsible for distributing power from the board. This connector plays a crucial role by connecting power from the R1 and R5 cores to the Q11 and Q51 cores respectively. This power distribution ensures that the board receives the necessary power to operate effectively, supporting the overall functionality of the control system.
• JQ connector connects to the JQR socket on the DTBA board. Its primary role is to carry contact input signals from the board to the board. This connection is vital for the transmission of input signals, allowing the board to process data accurately from various sensors and devices. Similarly, the JR connector connects to the JRR socket on the DTBB board, performing the same function as the JQ connector by carrying contact input signals for processing.
• For output signals, the JO1 connector writes the contact output (relay/solenoid) signals to the board in location four. This connector is generally not used in the Q11 core but is essential for controlling relay and solenoid actuators in other configurations. The JO2 connector also writes contact output signals but to the TCRA board in location five. Unlike JO1, JO2 is used in both the Q11 and Q51 cores, making it a more commonly utilized connector for relay and solenoid control.
• JX1 connector is a shielded twisted pair used for IONET signal transmission. In the Q11 core, the board writes signals to the JX2 connection on the TCEA board in location five of the P1 core. In the Q51 core, the board writes signals to the JX connection on the CTBA terminal board in the R5 core. This ensures high-speed and reliable transmission of IONET signals between different components of the control system. The JX2 connector serves the same function as JX1, providing flexibility by allowing either connector to be used based on specific configuration needs. 

Hardware Configuration

The board is equipped with eight hardware jumpers, each serving a specific function for the configuration and operation of the system. These jumpers are designed to ensure proper communication and functionality between various components of the control system.

• J1 and J8: These jumpers are reserved for factory test purposes. They are used during the manufacturing process to verify the board’s functionality and ensure that all systems are operational.
• J2 and J3: These jumpers are used for IONET termination resistors. The IONET (Input/Output Network) is a communication network used to connect various components. These jumpers help to properly terminate the IONET line, ensuring signal integrity and preventing communication errors.
• J4, J5, and J6: These jumpers are crucial for setting up the IONET ID for the board. Each board on the IONET must have a unique identifier to prevent conflicts during data transmission. These jumpers are used to configure the unique ID for this specific board, allowing it to communicate correctly within the network.
• J7: This jumper is used to enable the stall timer. The stall timer function is essential for detecting faults in the system, particularly in relay or solenoid outputs. When enabled, the stall timer monitors for prolonged periods of inactivity, triggering alerts or fault conditions if a stall is detected.

Software Configuration

• The board’s software configuration is managed through the I/O Configuration Editor, which is accessible on the Human-Machine Interface (HMI). This editor allows for the input of I/O configuration constants, which define the behavior of the system’s inputs and outputs, including contact input inversions.
• Contact Input Inversions: The software allows for the inversion of contact inputs. This means that the system can be configured to interpret the signal as active or inactive based on the desired logic, providing flexibility in how contact signals are handled within the system.
  Contact Input Circuits
• The board receives contact inputs from the DTBA and DTBB terminal boards via the JR and JQ connectors. These terminals allow the TCDA to monitor the state of various field devices. The input circuits on the board condition these signals to ensure they are correctly interpreted by the system.
• Once the contact inputs are received and processed, the board time tags any change of state. This feature allows the system to record the exact time when an input changes from one state to another, which is useful for diagnostics and tracking events within the system.
• These conditioned and time-tagged signals are then transmitted to the IONET via the JXI (JX2) connector. The JXI connector is used to send the processed data to the network for further processing or action.
• As mentioned earlier, the inversion of contact signals (where needed) is managed via software using the I/O configuration constants. This ensures that the system behaves as expected, regardless of the physical wiring or signal logic at the input.

Contact Output (Relay/Solenoid) Circuits

• The contact output signals generated by the board are transmitted to the TCRA boards, which manage the relays and solenoids connected to the system. These signals are sent via the JO1 and JO2 connectors. The contact outputs are typically used to activate or deactivate relays or solenoids that control physical processes in the system.
• These output circuits are essential for controlling the operation of machinery, valves, or other devices that require precise control through electrical signals. By managing the output signals through the TCDA, the system can automate operations based on the monitored contact inputs and the logic programmed into the control system.
