This single-slot unit features a 25 MHz 80386EX processor with a built-in math co-processor that enables hardware-based floating-point calculations. You will find this CPU ideal for applications requiring precise analog measurements, PID control, and accurate data processing. The IC693CPU352 offers 240 KB of user program memory with firmware 9.0 or later, and supports up to 2048 discrete inputs and outputs each. Moreover, this module includes three built-in serial ports for versatile communication with HMIs, SCADA systems, and other devices. With its advanced floating-point capability and large I/O capacity, the GE Fanuc IC693CPU352 stands as a top-tier choice for sophisticated process and machine control.

Technical Specifications

The IC693CPU352 delivers outstanding performance across all key metrics. Its 80386EX processor runs at 25 Megahertz, providing a typical scan rate of just 0.22 ms per 1K of Boolean logic. This speed ensures rapid response for time-critical control loops. The module provides 2048 discrete input points and 2048 discrete output points, covering large-scale digital control needs. For analog processing, it supports up to 32,640 analog input words and 32,640 analog output words maximum. The register memory holds up to 32,640 words (%R), while system registers offer 28,000 words for reference table viewing. Additionally, the IC693CPU352 includes 4096 bits of internal coils (%M) and 1280 bits of discrete global memory (%G). It supports over 2000 timers and counters, along with shift register and override instructions. The key differentiator for this CPU is its built-in math co-processor, which enables hardware-based floating-point math operations for precise calculations.

Floating-Point Math Capability

The GE Fanuc IC693CPU352 distinguishes itself with a dedicated math co-processor. This built-in hardware accelerator processes floating-point operations natively, delivering faster and more accurate results than software-based solutions. You will benefit from this feature when implementing PID control loops that require precise tuning parameters. Additionally, it proves invaluable for HMI and SCADA systems that need accurate decimal data readouts. The math co-processor handles fractional values efficiently, enabling better measurement accuracy and data computation. For applications involving complex arithmetic, such as flow calculations, temperature compensation, or motion profiles, the IC693CPU352 provides the processing power you need. This feature makes it particularly suitable for process industries, water treatment, and precision manufacturing.

Memory and I/O Capabilities

The GE Fanuc IC693CPU352 offers exceptional memory resources for demanding control strategies. The user program memory is 240 kilobytes when using firmware release 9.0 or later. For firmware versions prior to 9.0, the memory is 80 KB, so upgrading firmware unlocks the full capacity. The available user memory depends on allocation to register memory, analog inputs, and analog outputs. For analog I/O, this module handles up to 32,640 words for both inputs and outputs, providing virtually unlimited analog capacity. The discrete I/O capacity stands at 2048 inputs and 2048 outputs each, covering the largest Series 90-30 systems. Besides, the IC693CPU352 provides 256 bits of temporary output coils (%T) and 128 bits of system status references (%S, %SA, %SB, %SC). This comprehensive memory map ensures ample resources for even the most complex applications.

Communication and Expansion Options

Connectivity is a major strength of the IC693CPU352. It includes three built-in serial ports for versatile communication. The power supply connector port supports SNP slave and SNP-X slave protocols. Port 1 uses an RJ45 connector, while Port 2 uses a 9-pin D-sub connector. Both ports support RTU slave, SNP master/slave, and SNPX master/slave protocols. Native support covers SNP/SNPX slave and RTU slave operation. However, a PCM module is required for RTU master support, and a CMM module is needed for CMM support. For broader network integration, you can add optional communication modules such as Ethernet, Profibus, FIP, GBC, GCM, and GCM+. Moreover, this CPU supports configuration of up to seven expansion baseplates and seven remote I/O baseplates, offering extensive system scalability. A key-activated mode selector switch on the front panel provides hardware-based Run/Stop control.

Mechanical and Environmental Parameters

The GE Fanuc IC693CPU352 draws 910 milliamps at 5 Volts DC from the backplane power supply. The module does not draw current from the +12 Volts DC power supplies. Its heat dissipation rating is 4.55 Watts. The single-slot form factor fits standard Series 90-30 racks. The operating temperature range is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), suitable for most industrial environments. It also tolerates humidity from 5% to 95% non-condensing. The module includes a battery-backed real-time clock for time-stamping and scheduled operations. Front panel features include SNP, Port 1, and Port 2 LED indicators, along with a key switch for mode selection. The shield ground connector is located at the bottom of the module.

Software and Firmware

The IC693CPU352 requires specific software and firmware for optimal performance. It is configured using Logicmaster 90-30, VersaPro, or Proficy Machine Edition software. For firmware, release 9.0 and later unlocks the full 240 KB user memory. Earlier firmware versions limit memory to 80 KB. The CPU firmware is loaded through Port 1 onto the flash memory using the ladder software supplied with the firmware upgrade kit. Therefore, we recommend verifying your firmware version to ensure maximum memory availability. The GE Fanuc IC693CPU352 supports floating-point math through its built-in co-processor, which is essential for complex calculations in process control and motion applications.

Installation Guidelines

Installing the IC693CPU352 requires a Series 90-30 CPU baseplate. First, turn off all power to the system before handling any modules. Next, carefully align the CPU with the card guides and slide it into the designated slot until it seats firmly against the backplane connector. Then, secure the module using the retaining screws at the top and bottom edges. After installation, connect your programming device to Port 1 (RJ45) or Port 2 (9-pin D-sub). Use Logicmaster 90-30, VersaPro, or Proficy Machine Edition to configure the IC693CPU352 and download your ladder logic. For firmware updates, load the new firmware through Port 1 using the firmware upgrade kit. Finally, verify that all expansion and remote baseplates are properly cabled before powering up.
