Communication Interfaces

A 15-pin D-sub RS-232 port provides programming and HMI connectivity. A second RS-485 port supports multi-drop networks for remote I/O or drives. The GE IC693CPU350-CF includes a floating-point coprocessor for math-intensive tasks. You will find a 3-position DIP switch for configuration settings. A memory expansion port accepts optional EEPROM or RAM cartridges.

Energy Storage and Data Retention

The GE IC693CPU350-CF uses a lithium battery for retentive data backup. This battery maintains RAM contents for up to 6 months without external power. An internal supercapacitor provides 30 days of real-time clock backup. The module includes 10 KB of non-volatile flash for program storage. You do not lose application code when replacing the battery.

Internal Components and Indicators

A 16-bit microprocessor runs at 20 MHz for balanced performance. The front panel features 5 status LEDs for power, run, and I/O. You will find 16 diagnostic LEDs for communication and battery status. The GE IC693CPU350-CF contains approximately 198 surface-mount components. A memory cartridge slot accepts LM90 or VersaPro program storage cards.

System Integration and Use

Transitioning to this CPU enhances your Series 90-30 processing power significantly. You can program the module using LM90, VersaPro, or Proficy Machine Edition software. The processor supports up to 8 I/O racks over the expansion bus. Use the GE IC693CPU350-CF for bottling lines, stamping presses, or water treatment plants. For best results, update the firmware to the latest version before deployment.
