IC693CPU341 GE Fanuc CPU Series 90-30 PLC System

IC693CPU341 GE Fanuc CPU Module for Series 90-30

Product Introduction

The IC693CPU341 from GE Fanuc is a high-performance modular CPU designed for the Series 90-30 PLC family. This single-slot unit delivers powerful logic processing with a 20 MHz clock speed and a rapid Boolean execution time of just 0.3 milliseconds per 1K of logic. You will find this CPU ideal for complex machine control, material handling systems, and process automation tasks that demand both speed and memory capacity. The IC693CPU341 offers 80 KB of user program memory, which is significantly larger than many lower-tier models. It also supports extensive analog and discrete I/O configurations, giving you flexibility for diverse system designs. Moreover, this module integrates seamlessly with optional communication networks like Ethernet, Profibus, and FIP. With its robust feature set, the GE Fanuc IC693CPU341 remains a reliable workhorse for existing and upgraded Series 90-30 installations.

Technical Specifications

The IC693CPU341 excels with a well-rounded technical profile. Its core processor runs at 20 Megahertz, based on the 80C188XL microprocessor. The unit delivers a typical scan rate of 0.3 ms per 1K of Boolean logic, ensuring responsive control for time-sensitive applications. It provides 512 discrete input points and 512 discrete output points, along with 1024 analog input words and 256 analog output words. The register memory holds up to 9999 words (%R), and the module supports over 2000 timers and counters. Additionally, the IC693CPU341 includes 1280 bits of discrete global memory (%G) and 1024 bits of internal coils (%M). It also supports shift register, interrupt, and override instructions. However, please note that the serial communication port—supporting SNP and SNP-X slave protocols—is hosted by the power supply module, not embedded on the CPU itself. Furthermore, early hardware versions supported RAM with optional EPROM or EEPROM, but starting from version IC693CPU341-J with firmware 4.61, this CPU supports only RAM and optional Flash memory for program storage.

Memory and I/O Capabilities

The GE Fanuc IC693CPU341 offers substantial memory resources for demanding control strategies. The user program memory is 80 kilobytes, which accommodates large ladder logic programs and complex sequences. For analog processing, this module handles up to 1024 analog input words and 256 analog output words, making it suitable for applications with numerous sensors and actuators. The discrete I/O capacity stands at 512 inputs and 512 outputs each, covering most mid-sized industrial systems. Besides, the IC693CPU341 provides 128 bits of system status references (%S, %SA, %SB, %SC) and 256 bits of temporary output coils (%T). This comprehensive memory map ensures you have enough resources for data handling, status tracking, and temporary storage during program execution. Meanwhile, the battery-backed clock maintains time-stamping and scheduled operations even during power outages.

Communication and Expansion Options

Connectivity is a strong point for the IC693CPU341. It includes one built-in serial port that uses a connector on the PLC power supply, supporting SNP slave and SNP-X slave protocols for programming and HMI communication. For broader network integration, you can add optional communication modules such as Ethernet, FIP, Profibus, GBC, GCM, and GCM+. These options allow the GE Fanuc IC693CPU341 to connect to plant-wide networks, remote I/O, and supervisory systems. Moreover, this CPU supports configuration of up to five baseplates in total: one CPU baseplate plus four expansion or remote I/O baseplates. This scalability lets you expand your system as your application grows. Remember, the IC693CPU341 must be installed in slot 1 of the baseplate, and that slot cannot be used for any other module type except special option modules.

Mechanical and Environmental Parameters

The GE Fanuc IC693CPU341 draws 490 milliamps at 5 Volts DC from the backplane power supply. Its single-slot form factor fits standard Series 90-30 racks without occupying extra space. The operating temperature range is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), which covers most indoor industrial environments. It also tolerates humidity from 5% to 95% non-condensing. The module's solid construction resists shock and vibration, ensuring reliable operation on factory floors. Additionally, the battery-backed real-time clock maintains accurate timekeeping, and the unit supports PCM/CCM memory for extended data storage options.

Installation Guidelines

Installing the IC693CPU341 requires a Series 90-30 baseplate with an available slot 1. First, turn off all power to the system before handling any modules. Next, carefully align the CPU with the card guides in the rack 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 the serial port on the power supply module. Use Logicmaster 90-30 or compatible software to configure the IC693CPU341 and download your ladder logic. For firmware updates or memory changes, refer to the Program Utilities menu. Finally, verify that all expansion baseplates are properly cabled and terminated before powering up the system.
