GE Fanuc IC693CPU321 CPU Baseplate 10-Slot

IC693CPU321 GE Fanuc 10-Slot CPU Baseplate for Series 90-30

Product Introduction

The IC693CPU321 is a 10-slot embedded CPU baseplate from GE Fanuc's Series 90-30 PLC family. This unit integrates a 10 MHz 80188 microprocessor directly onto the baseplate, along with soldered memory circuits for RAM, EPROM, and EEPROM storage. It provides 12 KB of battery-backed user logic memory for application programs. The baseplate supports a maximum of 320 discrete inputs and 320 discrete outputs, or alternatively, 64 analog inputs and 32 analog outputs. Additionally, it includes a built-in RS-485 serial port for programming and communication. However, this baseplate does not support expansion or remote racks, making it suitable for standalone systems with up to ten I/O modules.

Technical Specifications

The IC693CPU321 delivers reliable performance for medium-scale control tasks. Its 80188 processor operates at 10 MHz, executing Boolean and non-Boolean functions efficiently. For memory, the module provides 12 KB of user logic storage with battery backup to preserve data during power loss. In terms of I/O capacity, it supports up to 320 discrete input points and 320 discrete output points. Moreover, it accommodates 64 analog input words and 32 analog output words for applications requiring analog signal processing.

This baseplate draws 430 milliamps at 5 Volts DC from the backplane. It features one 15-pin D-type RS-485 port located on the power supply, which connects to programming computers, handheld programmers, or other serial devices. Furthermore, the IC693CPU321 supports various communication options through optional modules, including Serial SNP, RTU, LAN-Genius, Ethernet SRTP, Ethernet Modbus TCP, Profibus-DP, and DeviceNet.

Memory and Storage Architecture

The IC693CPU321 incorporates multiple memory types directly soldered to the baseplate circuit. RAM provides volatile storage for user logic and data, while a backup battery retains this content during power interruptions. EPROM and EEPROM offer non-volatile storage options for more permanent data retention. Since all memory chips are firmly attached to the backplane, they are less susceptible to vibration or disconnection issues. This design enhances overall system reliability in industrial environments. Additionally, the battery-backed memory ensures that critical programs remain intact even after extended power outages.

Mechanical and Environmental Specifications

This embedded CPU baseplate is built for dependable operation in factory settings. Its operating temperature ranges from 0 to 60°C, while storage temperatures span from -40 to 85°C. Relative humidity should remain between 5% and 95%, non-condensing. Weighing approximately 2.2 pounds (1.0 kg), the IC693CPU321 is relatively lightweight for a 10-slot baseplate.

For installation, the baseplate provides ten I/O slots for various Series 90-30 modules. The power supply occupies a dedicated position, and the RS-485 port is accessible on the power supply unit itself. Because this unit lacks an expansion connector, you cannot attach additional racks. Therefore, all I/O modules must fit within the ten available slots.

Installation and Configuration Guidance

Proper setup of the IC693CPU321 requires careful slot planning and software configuration. The ten I/O slots can host a mix of discrete and analog modules, specialty cards, or communication interfaces. However, since expansion is not supported, ensure that your total I/O count does not exceed the baseplate's capacity. Specifically, you can use up to 320 discrete points or 64 analog inputs and 32 analog outputs in any combination.

For programming, you can use Logicmaster 90-30 (DOS-based), VersaPro (Windows-based), or Proficy Logic Developer Machine Edition. The built-in RS-485 port provides a direct connection to a personal computer running these software packages. Alternatively, you can install optional communication modules for Ethernet or fieldbus connectivity. Additionally, always verify that the total backplane current draw from all installed modules, including the IC693CPU321 itself, stays within the power supply's capacity.

Frequently Asked Questions

1. Does the IC693CPU321 support expansion or remote racks?
No, the IC693CPU321 does not include an expansion connector. Therefore, it cannot connect to additional expansion or remote racks. Your I/O configuration must fit entirely within the ten available slots.

2. What is the maximum I/O capacity for this baseplate?
The IC693CPU321 supports up to 320 discrete inputs and 320 discrete outputs, or alternatively, 64 analog input words and 32 analog output words. You can mix discrete and analog modules as long as you stay within these limits.

3. What programming software works with this CPU?
You can program the IC693CPU321 using Logicmaster 90-30 (DOS-based), VersaPro Professional Edition, or Proficy Logic Developer Machine Edition. All of these support the RS-485 serial connection.

4. How is the user memory protected during power loss?
The IC693CPU321 uses a battery-backed RAM system to preserve user logic and data. The battery is located on the power supply and maintains memory contents during power outages.

5. Can I use Ethernet communication with this baseplate?
Yes, but you will need to install an optional Ethernet communication module in one of the I/O slots. The baseplate supports Ethernet SRTP and Ethernet Modbus TCP through these optional modules.
