Ge Fanuc 90-30 PLC IC693CPU352 - Simple Guide for Electricians

Overview: The IC693CPU352 is a single-slot CPU module designed for large projects, offering high memory capacity and processing speed. It supports a total of 8 baseplates (1 CPU baseplate + 7 expansion or remote baseplates). Starting with firmware release 9.0, the memory capacity has been increased, making it ideal for more complex 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 7 additional baseplates for expansion, making it a perfect solution for large systems.
    Battery-Backed Clock: The CPU includes a battery-backed clock, which retains time-based data even when the system is powered off.
    Built-in Serial Ports: There are 3 built-in serial ports that support SNP/SNPX slave, RTU slave, and master/slave modes, as well as Serial I/O on Ports 1 and 2. A CMM module is required for CCM support, and a PCM module is needed for RTU master support.

Technical Details:

    Processor Speed: Operates at 25 MHz, providing fast and powerful performance.
    Scan Rate: It scans at 0.22 milliseconds per 1K of logic.
    User Program Memory: With firmware version 9.0, it offers up to 240K bytes of program memory. Earlier versions have a fixed size of 80K bytes.
    Input/Output Points: Supports 2,048 discrete input points and 2,048 discrete output points.
    Internal Coils: Includes 4,096 bits for internal coils and 256 bits for temporary output coils.
    Analog Inputs/Outputs: Configurable up to 16,384 words for analog inputs and outputs (with firmware 9.0 and later).
    Timers/Counters: Provides more than 2,000 timers and counters, suitable for large-scale operations.
    Communications: Supports Ethernet, Profibus, FIP, and other communication modules, along with multi-drop connections via LAN.
    Floating Point Math Support: Hardware-based floating-point math calculations are supported through the built-in math co-processor.

Things to Watch Out For:

    Memory Storage: Supports both RAM and Flash memory. Firmware version 9.0 allows for configurable memory.
    Additional Modules May Be Needed: A CMM module is required for CCM support, and a PCM module is needed for RTU master support.

The IC693CPU352 is a powerful CPU for large projects and complex systems, offering high memory capacity and processing speed. With expansion support, advanced communication options, and features like a battery-backed clock, it provides a reliable and flexible solution for demanding applications.
