GE Fanuc Series 90-30 CPU IC693CHS391H and Com Module AD693CMM301A
The GE Fanuc Series 90-30 platform includes the IC693CHS391H CPU module and the AD693CMM301A communication module, together forming a powerful control and networking solution. The CPU handles logic execution and I/O scanning, while the communication module enables connectivity to external devices and higher-level systems.
IC693CHS391H CPU Module
This CPU is equipped with a 32-bit processor running at 25 MHz, providing fast execution of ladder logic and function blocks. It includes 240 KB of user program memory and 120 KB of data memory, with battery-backed retentive storage. The CPU supports up to 2048 digital I/O and 256 analog I/O points, with a scan time of approximately 0.8 ms per 1K instructions.
It features a built-in RS-232 port for programming (via SNP protocol) and a RS-485 port for multi-drop networking. The CPU also has a real-time clock and a watchdog timer for monitoring system health. Status LEDs indicate power, run/stop, and communication activity.
AD693CMM301A Communication Module
This module is a dedicated communication coprocessor that adds fieldbus and serial networking capabilities to the Series 90-30 system. It supports multiple protocols including Modbus RTU, Profibus DP (master/slave), and GE's proprietary Genius bus. The module has its own processor and memory, offloading communication tasks from the CPU.
It includes one RS-232 port, one RS-485 port, and optional fiber-optic interfaces. The module can be configured as a gateway to connect the PLC to SCADA systems, HMI panels, and other PLCs. It also supports data mapping and messaging functions.
Combined Operation
When used together, the CPU handles control logic while the communication module manages data exchange. The two modules communicate through the Series 90-3 backplane, sharing data via common memory. This architecture improves overall system throughput and determinism.
Environmental and Electrical Data
Operating temperature: 0 to 60°C for both modules. Power consumption: CPU draws 500 mA from 5 V; Com module draws 400 mA. Both are designed for rack mounting in Series 90-30 chassis.
Programming and Configuration
Programming is done using GE's Proficy Machine Edition software, supporting ladder, function block, and structured text. The communication module is configured through dedicated software that sets baud rates, protocol parameters, and data mapping tables.
Applications
These modules are used in a variety of industries including automotive, food and beverage, and water treatment, where reliable control and flexible communication are essential.
Maintenance and Diagnostics
Both modules provide extensive diagnostic information via status LEDs and software-accessible fault tables. Firmware updates are possible via serial or network connections.
Certifications
CE, UL, and CSA approved. Compliant with IEC 61131-2 standards.
In summary, the GE Fanuc IC693CHS391H CPU and AD693CMM301A communication module deliver a robust, scalable control and networking foundation for industrial automation systems.
