Product Description

The IC693CPU370 is a high performance Central Processing Unit. This unit is the "brains" of the PLC and is where most of the calculations take place. The GE Fanuc IC693CPU370 has CPU firmware stored in flash memory. This CPU unit is for entry-level applications that have low I/O counts. As the CPU is embedded into the backplane, all the slots are available for either input or output devices.

The model 370 is compatible with a range of advanced modules. This includes control, Ethernet and various bus modules.  The mid-range models are modular and available in different memory sizes. The range also has different performance capabilities and increased functionality. For example, the units have features like override, a battery-backed clock and support for a Programmable Coprocessor.

High-performance CPU modules have a design that is based on the latest 386EX processor. This allows for fast computation and high throughput. These units are able to handle up to 4,096 I/O points and they start at 32K of memory. Furthermore, they are programmable in a number of standard languages. The IC693CPU370 module has 2048 analog points. It is a 32-bit system that requires a high-capacity power supply to operate. It has a processor speed of 133 Mhz and a register memory of 240 kB.

Customer Questions and Answers

  • Question:  What is an IC693CPU370?  Answer:  The IC693CPU370 is a high performance Central Processing Unit. This unit is the "brains" of the PLC and is where most of the calculations take place.
  • Question:  What features does IC693CPU370 provide?  Answer:  It has high speed Boolean and non-Boolean processing provided by a 586-class 133MHz processor.
    • It has support for EZ Store Device that allows you to download a program without a PC. (Requires a CMM321 Ethernet module for programmer connection.)
    • It has 240KB of user memory.
    • It has support for Ethernet communications through an IC693CMM321 Ethernet Interface module allowing you to connect the PLC directly to an Ethernet LAN using TCP/IP via a user-supplied transceiver and AAUI cable. 
  • Question:  What power supply does IC693CPU370 require?  Answer:  IC693CPU370 requires a high capacity power supply.
  • Question:  Is there anything recommended for this processor?  Answer:  Yes, because the built-in battery is limited to 1.2 months of continuous power outage, an IC693ACC302 external battery is recommended.
