- Robust Design: The cable assembly is built to withstand the rigors of industrial use. Its robust design includes features that enhance its resistance to wear, environmental factors, and potential mechanical stresses.
- To ensure the reliability and precision of signal transmission, the cable features high-quality conductors and shielding. The conductors are carefully designed to minimize signal loss and maintain optimal conductivity, resulting in accurate signal transmission. Additionally, the shielding helps to minimize electromagnetic interference, preventing signal degradation and ensuring consistent and precise signal integrity.
- The cable assembly is equipped with connectors on both ends, enabling easy and secure connections to compatible interfaces. These connectors are designed to provide a robust and reliable connection, ensuring a stable and uninterrupted signal flow. They are constructed to withstand repeated mating cycles and provide a secure fit, reducing the risk of signal loss or disconnections during operation.
- It is well-suited for applications that require the transmission of analog and discrete signals over relatively long distances. With its reliable signal transmission capabilities and high-quality construction, it can effectively maintain signal integrity even over extended cable lengths. This makes it a preferred choice for industrial control systems, such as those found in manufacturing plants, power generation facilities, and process automation environments.
MicroNet Plus Redundant Operation
- The MicroNet Plus system offers a redundant master/standby configuration to enhance operational availability and ensure continuous system performance. This redundancy feature provides a seamless transition in the event of a master CPU failure, minimizing any potential disruptions in the control and operation of the system.
- One of the key aspects of the redundant operation is the synchronized memory between the master and standby CPUs. This synchronized memory ensures that both CPUs have access to the same operating information, allowing for consistent and accurate control of the system. By sharing synchronized memory, the standby CPU remains up-to-date with the latest system status and data.
- In the event of a master CPU failure, the entire system control, including I/O control, is swiftly transferred to the standby CPU in less than 1 ms. This rapid transfer ensures that the prime mover, which could be a turbine or other critical equipment, continues to operate smoothly without any interruptions. The standby CPU seamlessly takes over the control responsibilities, ensuring the system remains operational and responsive.
- Once the master CPU issue has been resolved or fixed, there are two options for further operation. The system can either continue to run on the standby CPU, ensuring continuous functionality, or the control can be transferred back to the original master CPU. This flexibility allows for the appropriate course of action to be taken based on the specific requirements and circumstances of the situation.
- During the control transfer process, communication links play a crucial role in announcing and coordinating the transition. These communication links facilitate the exchange of control signals and information between the master and standby CPUs. By utilizing these links, the system ensures that all components and devices are aware of the control transfer, maintaining synchronization and synchronization between the CPUs.
- The redundant master/standby configuration of the MicroNet Plus system provides enhanced availability and reliability. By quickly and seamlessly transferring control between CPUs, the system minimizes downtime and ensures uninterrupted operation. This feature is especially critical in applications where continuous operation is vital, such as power generation, industrial processes, and other mission-critical systems.
- The MicroNet Plus control system is equipped with an SNTP (Simple Network Time Protocol) version 4 compliant timeserver. This feature enables the control system to synchronize its internal clock with an external time source, ensuring precise and accurate timekeeping.
- With synchronization capability in less than 1 millisecond, the system can align its operations with other time-dependent processes or external systems.
- The control system supports time stamping of sequences of events, allowing for accurate recording and synchronization of events within the system.
- Discrete I/O can be time-stamped with a resolution of up to 1 millisecond, providing detailed information on the timing of digital events. Analog I/O, on the other hand, supports software process variables with a resolution of up to 5 milliseconds, enabling precise monitoring and control of analog signals.
Prime Mover Control
- The functionality and performance of the MicroNet Plus control system are specifically developed to meet the stringent requirements of prime mover control. Prime movers are typically large engines or turbines used to generate mechanical power, such as in power generation or industrial applications.
- MicroNet Plus system is designed to provide reliable and precise control over prime movers, ensuring optimal performance and efficiency.
CPU Capabilities and Recursion Rates
- The MicroNet Plus control system utilizes powerful CPUs (Central Processing Units) to execute control algorithms and process data. The capabilities of the CPU, including its processing power and memory capacity, are carefully engineered to handle the computational requirements of the control system.
- Application software recursion rates and determinism are optimized to provide fast and predictable control loops, enabling precise control over the prime mover.
I/O Signal Conditioning and Filtering
- To ensure accurate and reliable measurement of signals, the MicroNet Plus system incorporates signal conditioning and filtering techniques.
- Signal conditioning involves amplifying, filtering, or converting input signals to match the requirements of the control system. This process enhances signal quality and reduces noise and interference.
- Filtering techniques are employed to remove unwanted noise and disturbances from the signals, improving the overall performance and reliability of the control system.
Cabinet Structural Grounding
- The enclosure for the system should be a shielded enclosure with six sides designed to mitigate electromagnetic interference (EMI). The interior surfaces of this enclosure must possess conductive properties and be coated with protective treatments to prevent corrosion.
- To ensure effective cable management, the enclosure's floor and/or top must incorporate openings for cable entry. These access areas should be limited to either the floor or top panels. The dimensions of these openings should not exceed 152 mm (6 inches) in their largest dimension. This precaution is especially crucial when cable access points are in proximity to radio frequency (RF) transmitters like push-to-talk radios or cell phones.
- For proper grounding, the cabinet frame and mounting areas must be securely bonded (grounded) together. All screws used to mount the MicroNet chassis (8-32 M4) should be properly installed to establish a grounded connection between the chassis and the mounting plate.
- The frame of the cabinet should maintain low electrical resistance at each structural connection point (2.5 mohm). The same criterion applies to the mounting plates, which should be connected to the structural frame at multiple points, with a minimum of six places (4 corners and 2 mid-points) and a preferred eight places.
- In terms of cabinet doors, they must be electrically connected to the main structural frame with a resistance of less than 2.5 mohm. To ensure this connection, conductive EMI gaskets should be used along the length of the interface where the doors meet the frame.
- Likewise, cover panels within the enclosure must also be electrically connected to the structural frame with a resistance of less than 10 mohm. This connection can be achieved using conductive EMI gaskets applied along the interface where the cover panels meet the frame.
- Both the floor and top of the enclosure need to be electrically connected to the structural frame, ensuring a resistance of less than 2.5 mohm. Conductive EMI gaskets should be utilized along the length of the interfaces where the floor and top panels meet the frame.
- To maintain a proper electrical connection, the DIN rail should also be bonded to the structural frame with a resistance of less than 2.5 mohm. To achieve this, a minimum of two screws should be used to secure the DIN rail to the cabinet frame at intervals of 300 mm (12 inches).
