Functional Description
IS200SSCAH2ACB is a Serial Communications Terminal Board developed by GE. It is a part of Mark VI control system. The board, or Simplex Serial Communication Input/Output board, serves as a compact terminal board facilitating serial communication within the system. The board accommodates up to six communication channels, offering flexibility in configuration. Each channel supports RS-232C, RS-485, or RS-422 signaling, catering to diverse communication needs.
Features
- Terminal Blocks: High-density Euro-style box-type terminal blocks are employed for efficient wiring and connectivity. These terminal blocks provide reliable connections for interfacing with external devices or systems.
- On-board ID Chip: An integrated ID chip is embedded within the board, serving the purpose of identifying the board to the PSCA I/O pack for diagnostic purposes. This chip aids in system troubleshooting and maintenance by providing crucial identification information.
- System Compatibility: Designed to seamlessly integrate with the PSCA I/O pack, ensuring compatibility and interoperability within the system architecture.
- Diagnostic Support: By incorporating an ID chip, the board enhances diagnostic capabilities, allowing for efficient identification and resolution of system issues or faults.
- Simplicity: Available only in a simplex version, emphasizing simplicity and ease of use in its design and functionality.
Installation
- Mounting: The board is typically mounted on a DIN rail using a sheet metal carrier and plastic insulator mount. Alternatively, it can be directly bolted into a cabinet for added stability.
- Terminal Block Selection: Equipped with a right-angle header that accepts various commercially available pluggable terminal blocks. It also offers 48 terminals, but the advantage lies in the flexibility to use different types of terminal blocks based on specific requirements or preferences.
- Terminal Block Installation: Depending on the chosen variant, install the terminal block accordingly. For SSCAH1, the terminal block is already mounted permanently. For
- SSCAH2, attach the pluggable terminal blocks to the right-angle header, ensuring a secure connection.
- Secure Mounting: Once the terminal block is in place, ensure that the board is securely mounted on the DIN-rail or cabinet. Verify that the mounting arrangement provides adequate support and stability to the board.
Diagnostics
- JA Connector Identification: The JA connector on the terminal board contains an ID device that stores essential information about the board. This ID device is a read-only chip that holds data such as the terminal board's serial number, board type, revision number, and the J connector location. When the PSCA I/O pack interrogates this ID device, it retrieves the stored information for identification purposes.
- Compatibility Check: The information obtained from the ID device is compared with the expected specifications by the I/O processor. If a mismatch is detected between the retrieved data and the expected values, it indicates a hardware incompatibility issue. In such cases, a hardware incompatibility fault is generated, signaling that there may be a problem with the terminal board's configuration or components.
- Fault Handling: Upon detecting a hardware incompatibility fault, appropriate actions need to be taken to resolve the issue. This may involve verifying the terminal board's serial number, revision number, and other relevant details to ensure they match the expected values. If necessary, the terminal board may need to be reconfigured or replaced to address the compatibility issue and restore proper functionality.
Configuration
- The jumpers JP1A through JP6A and JP1B through JP6B are primarily used to apply or remove termination resistors between specific signal lines, typically labeled as A, B, C, and D, for each of the six serial communication channels. Termination resistors are essential for preventing signal reflection and ensuring proper impedance matching along the communication lines. By configuring these jumpers, users can tailor the termination characteristics to match the requirements of the communication protocol and the overall system setup.
- In addition to termination resistors, jumpers JP1R through JP6R are utilized to select whether the return path of the communication signals has a resistive or capacitive connection to the SCOM (Serial COMmunication) interface. This selection impacts the electrical characteristics of the return path, influencing signal integrity and noise immunity. The choice between resistive and capacitive connections is made based on the specific requirements of the communication environment and the desired level of signal stability.
- Configuration of these jumpers is typically detailed in the operational documentation provided with the terminal board. Operators and technicians refer to this documentation to locate the specific jumper positions corresponding to JP1A to JP6R and make adjustments accordingly. Proper configuration ensures that the serial communication channels operate efficiently and reliably, meeting performance expectations and minimizing potential signal interference.
- Properly configuring the terminal board jumpers is critical for achieving optimal performance and reliability in serial communication systems. Incorrect jumper settings can lead to signal degradation, communication errors, and unreliable data transmission. Therefore, careful attention to detail during the configuration process is essential to maintaining system integrity and ensuring seamless operation across all communication channels.
- The jumper-based configuration approach provides flexibility to accommodate different communication protocols and system configurations. It allows for customization based on specific application requirements, ensuring compatibility with various serial communication standards and optimizing system performance in diverse industrial and commercial settings.
