Ge Fanuc 90-30 PLC IC693CPU341 - Simple Guide for Electricians

Overview: The IC693CPU341 is a single-slot CPU module that offers large memory capacity and fast processing for more complex tasks. It supports a total of 5 baseplates (1 CPU baseplate + 4 expansion or remote baseplates), making it ideal for larger systems.

Key Features:

    Single-Slot CPU Module: The CPU occupies just one slot on the baseplate, leaving the other slots available for I/O or option modules.
    Expansion Support: You can connect up to 4 additional baseplates for expansion, providing a flexible solution for larger and more complex systems.
    Battery-Backed Clock: This model includes a battery-backed clock, allowing it to retain time-based data even when the system is powered off.
    Built-in Serial Port: There is 1 built-in serial port that supports SNP and SNP-X slave protocols. If you need master support or other protocols like RTU, you'll need to add a CMM or PCM module.

Technical Details:

    Processor Speed: Runs at 20 MHz, making it fast and powerful for complex operations.
    Scan Rate: It scans at 0.3 milliseconds per 1K of logic.
    User Program Memory: Offers up to 80K bytes of program memory, making it suitable for larger and more complex programs.
    Input/Output Points: Supports 512 discrete input points and 512 discrete output points.
    Internal Coils: Includes 1024 bits for internal coils, and 256 bits for temporary output coils.
    Analog Inputs/Outputs: Supports 1024 words of analog input and 256 words of analog output.
    Timers/Counters: Provides more than 2000 timers and counters, offering plenty of capacity for complex tasks.
    Communications: Supports LAN, Ethernet, Profibus, FIP, and other communication modules, with multi-drop connection options via LAN.

Things to Watch Out For:

    Memory Storage: Initially supports RAM with optional EPROM or EEPROM. However, starting with hardware version IC693CPU341-J and firmware Release 4.61, only RAM and optional Flash memory are supported.
    Additional Modules May Be Needed: If you need SNP/SNP-X master, CCM, or RTU support, you will need to add a CMM or PCM module.

The IC693CPU341 is a powerful CPU for larger projects and complex systems. With its fast processor, large memory capacity, and flexible expansion options, it’s a great choice for demanding applications. Its battery-backed clock and robust communication support make it a reliable solution for advanced setups.
