Functional Description

IC693CHS391 is an expansion plate developed by GE. It is a part of Mark I and II control system. It is a versatile expansion plate designed to enhance the functionality and connectivity of control systems. It features ten slots, each tailored for specific components to ensure efficient and reliable system performance.

Features

  • The expansion plate comes with ten slots. The slot at the left end is uniquely sized to accommodate the power supply, ensuring compatibility and correct installation.
  • The dedicated slot for the power supply is designed with a unique size to ensure that only the power supply can be installed in this position. This helps prevent incorrect component installation and ensures the system receives the necessary power.
  • The first slot of the baseplate is designated for the CPU module and is labeled CPU/1. Each system can only have one CPU baseplate. If additional baseplates are needed, they must be either Remote or Expansion baseplates.
  • Slots numbered 2 and above have unique sizes and are used to connect either option modules or I/O modules. This design ensures flexibility and scalability, allowing the system to be customized with various modules as needed.
  • For systems using remote baseplates, the required cable length should be less than 700 feet. For expansion and CPU baseplates, the cable length should be less than 50 feet. These specifications help ensure signal integrity and reliable communication between baseplates.
  • Both remote and expansion baseplates are associated with DIP switches. These switches are used to configure the baseplates, ensuring proper communication and functionality within the system.

Connectivity

  • It is equipped with a 25-pin female connector located on the right end of the base plate. This connector is used to link the expansion plate to either a remote or expansion baseplate, facilitating seamless system expansion.
  • Remote and expansion baseplates must be connected to the system with a CPU. The number of these baseplates supported by a system depends on the type of CPU used:
  • A maximum of four baseplates can be supported by CPUs 341, 340, and 331.
  • A maximum of seven baseplates can be supported by CPU 350.

Installation and Usage

  • Users must ensure it is correctly connected to the CPU in the first slot of its baseplate. Proper installation and configuration are crucial for system performance and reliability.
  • The ability to connect multiple option modules or I/O modules in the slots above slot number 2 provides significant customization options. Users can tailor the system to meet specific requirements, enhancing its capability and efficiency.
  • The expansion plate's design allows for easy system scalability. By adding additional remote or expansion baseplates, users can expand the system’s functionality without compromising performance.

Modular CPU Baseplates

  • Dedicated Power Supply Slot: The leftmost slot on the modular CPU baseplate is specifically designed for the installation of a Power Supply module. This slot is not numbered and has a unique size and type, making it incompatible with any module other than the Power Supply. This specialization ensures that the power supply is securely fitted and that power distribution is efficiently managed across the system.
  • Installation of CPU or Special Option Modules: Slot 1 of the modular CPU baseplate is designated for a CPU module or a special Option module. This slot is also uniquely sized and shaped to accommodate only the CPU module or specific options, such as the FIP Remote I/O Scanner (IC693BEM330). The labeling of this slot as CPU/1 clearly identifies its intended use, ensuring correct module placement and functionality within the system.
  • Additional Module Slots: Slots numbered 2 and above on the modular CPU baseplates are designed exclusively for I/O modules or other Option modules. Each of these slots maintains a unique size and type that distinguishes them from the Power Supply and CPU slots, providing a clear structure for system expansion and versatility. This configuration allows users to mix and match various I/O and Option modules based on their specific application requirements.
  • Connection for Expansion and Remote Baseplates: The modular CPU baseplates are equipped with a 25-pin D-type female expansion connector located at the right end of the baseplate. This connector is used for interfacing with Expansion or Remote baseplates, allowing for the seamless addition of extra modules and capabilities as needed. This feature is essential for scaling up system performance and ensuring that the baseplate can accommodate future expansion without requiring a complete redesign.
  • Modular Design Benefits: One of the significant advantages of the modular CPU baseplate design is the flexibility it offers. Users can replace the existing CPU module with a different type if additional features or enhanced functionalities are required. This modular approach minimizes downtime and allows for easy upgrades without necessitating extensive reconfiguration of the entire system.
  • Single CPU Baseplate Requirement: In any given system, only one modular CPU baseplate is permitted. If additional baseplates are required, they must be of the Expansion or Remote types, which are designed specifically to complement the primary CPU baseplate. This limitation ensures that the system architecture remains organized and efficient, preventing potential conflicts or issues that may arise from multiple CPU installations.
  • Rack Number 0: Each modular CPU baseplate is assigned a default Rack Number 0. This default designation helps in identifying the baseplate within the system, particularly when configuring or troubleshooting the system. The clear numbering system enhances operational clarity and facilitates easier management of the system components.
