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

  • It features ten slots, each tailored for specific components within the control system. This design enables modular expansion, allowing users to integrate necessary power, CPU, and I/O modules efficiently.
  • The leftmost slot is uniquely sized to accommodate the power supply module, ensuring compatibility and correct installation. This dedicated design prevents incorrect placement of other components in the power supply slot, reducing errors in system setup.
  • The first slot, labeled CPU/1, is specifically designated for the CPU module. Only one CPU baseplate is allowed per system—any additional baseplates must be Remote or Expansion baseplates. This ensures a structured and scalable system architecture.
  • Slots numbered 2 and above have unique dimensions and are designed for option modules or I/O modules. This allows for system flexibility, enabling users to expand functionalities with various input and output modules.
  • The cable length requirements vary depending on the type of baseplate. The cable length should be less than 700 feet to ensure optimal data transmission. Expansion and CPU baseplates: The cable length should not exceed 50 feet to maintain signal integrity and system stability. These guidelines help in avoiding signal degradation and ensuring smooth communication between components.
  • Remote and expansion baseplates are equipped with DIP switches that allow users to configure system settings. These switches help in defining communication parameters, ensuring that each baseplate integrates seamlessly within the control system. Proper configuration of DIP switches enhances system reliability and prevents miscommunication between modules.

Connectivity

  • Equipped with a 25-pin female connector, which is located at the right end of the baseplate. This connector is used to establish a reliable connection between the expansion plate and either a remote baseplate or another expansion baseplate. By linking additional baseplates, the system can scale up efficiently, accommodating more I/O modules and control components as needed.
  • Remote and expansion baseplates must be directly connected to a system that includes a CPU module. The CPU acts as the central controller, managing communication and data exchange between all connected baseplates. Without a CPU, remote and expansion baseplates cannot function independently within the system.
  • The number of baseplates that can be connected in a system depends on the type of CPU used. CPUs 341, 340, and 331 models can support a maximum of four (4) baseplates in the system. This includes the main CPU baseplate and up to three (3) additional expansion or remote baseplates.
  • CPU 350 model allows for a maximum of seven (7) baseplates in total. This configuration includes the main CPU baseplate and up to six (6) additional remote or expansion baseplates. The increased baseplate capacity provides greater system scalability, making CPU 350 a better choice for larger control system setups.

Installation and Usage

Proper installation and usage of the expansion plate are essential for ensuring system performance, reliability, and scalability. This component is designed to enhance control systems by enabling additional module connections, allowing users to customize and expand their setup based on specific operational needs.

  • Proper Connection to the CPU: The expansion plate must be correctly connected to a CPU module for the system to function effectively. The CPU must be installed in the first slot (labeled CPU/1) of its designated baseplate. Ensuring a secure and correct connection between the CPU and the expansion plate is vital to maintaining system stability and preventing communication errors.
  • Configuration and System Reliability: After installation, proper configuration of the expansion plate and connected modules is required to ensure smooth operation.
    The system must be set up correctly using DIP switches to establish communication parameters, which helps the CPU recognize and interact with the expansion plate.
    Incorrect configuration can lead to system failures, communication errors, or reduced performance.
  • Customization with I/O and Option Modules: The expansion plate provides users with flexibility in system design by supporting multiple option modules or I/O modules. Slots numbered 2 and above can accommodate various modules, allowing users to tailor the system according to specific operational needs. These modules can include Analog and digital I/O modules, Communication modules, and Specialized control modules. This customization capability enhances system efficiency and functionality by enabling integration of the required components without unnecessary limitations.
  • Seamless System Scalability: The expansion plate is specifically designed to support system expansion, making it an ideal choice for growing industrial applications. Users can easily scale their control system by adding additional remote or expansion baseplates, which allows for Increased module capacity, Improved process automation, and Enhanced operational flexibility. This scalability feature ensures that businesses can adapt to evolving needs without compromising system performance or reliability. 

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 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 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 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 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 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.
