This single-slot unit features a 25 MHz 80386EX processor that delivers exceptional processing speed and memory capacity. You will find this CPU perfect for complex automation tasks that require fast scan rates, large program storage, and extensive I/O handling. The IC693CPU351 offers 240 KB of user program memory, which is three times larger than many mid-range models. It supports up to 2048 discrete inputs and outputs each, along with massive analog I/O capacity. Moreover, this module includes three built-in serial ports for flexible communication with HMIs, SCADA systems, and other devices. With its advanced feature set including floating-point math and a key switch, the GE Fanuc IC693CPU351 stands as a top choice for sophisticated control systems.

Technical Specifications

The IC693CPU351 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, making it suitable for data-intensive applications. The register memory holds up to 32,640 words (%R), while the system registers offer 28,000 words for reference table viewing. Additionally, the IC693CPU351 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. Importantly, this CPU supports floating-point math functions, which the lower-tier models lack.

Memory and I/O Capabilities

The GE Fanuc IC693CPU351 offers exceptional memory resources for the most 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. This large memory accommodates extensive ladder logic, complex sequences, and data tables. For analog I/O, this module handles up to 32,640 words for both inputs and outputs, providing virtually unlimited analog capacity for large processes. The discrete I/O capacity stands at 2048 inputs and 2048 outputs each, covering the largest Series 90-30 systems. Besides, the IC693CPU351 provides 256 bits of temporary output coils (%T) and 128 bits of system status references (%S, %SA, %SB, %SC). This comprehensive memory map ensures you have ample resources for even the most complex applications.

Communication and Expansion Options

Connectivity is a major strength of the IC693CPU351. It includes three built-in serial ports for versatile communication. The power supply connector port supports SNP slave and SNP-X slave protocols. Ports 1 and 2 support RTU slave, SNP master/slave, and SNPX master/slave protocols. This flexibility allows the GE Fanuc IC693CPU351 to connect to multiple HMIs, SCADA systems, and programming devices simultaneously. For broader network integration, you can add optional communication modules such as Ethernet, Profibus, FIP, GBC, GCM, and GCM+. These options enable plant-wide networking and remote I/O connectivity. Moreover, this CPU supports configuration of up to seven expansion baseplates and seven remote I/O baseplates, giving you extensive system scalability. A key switch on the module provides hardware-based protection against unauthorized program changes.

Mechanical and Environmental Parameters

The GE Fanuc IC693CPU351 draws 890 milliamps at 5 Volts DC from the backplane power supply. This higher current consumption reflects its increased processing power and memory capacity. Its 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. A sequential event recorder is also available for troubleshooting and process analysis.

Software Compatibility

The IC693CPU351 requires specific software versions for full functionality. It is supported by Logicmaster 90-30, microprogramming, and configuration software release version 6.0 and later. Additionally, it works with control programming and configuration software release version 2.0 and later. For firmware, release 9.0 and later unlocks the full 240 KB user memory. Earlier firmware versions limit memory to 80 KB. Therefore, we recommend verifying your firmware version to ensure optimal performance. The GE Fanuc IC693CPU351 also supports floating-point math, which is essential for complex calculations in process control and motion applications.

Installation Guidelines

Installing the IC693CPU351 requires a Series 90-30 5-slot or 10-slot 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 slot 1 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 any of the three serial ports. Use Logicmaster 90-30 version 6.0 or later to configure the IC693CPU351 and download your ladder logic. For firmware updates, refer to the Program Utilities menu. Finally, verify that all expansion and remote baseplates are properly cabled before powering up.
