GE Fanuc IC693CPU363 CPU Module

Description

The IC693CPU363 is a high-performance Central Processing Unit (CPU) for the GE Fanuc (now Emerson) Series 90-30 PLC system. It is part of the "360 series" of processors, which utilized the 32-bit 80386EX microprocessor to provide faster logic execution and expanded memory compared to earlier 90-30 models.

Specifications

• Part Number: IC693CPU363
• Processor: 80386EX running at 25 MHz.
  
• User Memory: 240 KB (RAM and Flash).
  
• Scan Rate: 0.22 ms per 1K of Boolean logic.
  
• I/O Capacity: Supports up to 4,096 Discrete I/O points.
• Analog I/O: Supports 2,048 %AI and 512 %AQ channels.
• Register Memory (%R): 32,640 words.
• Baseplate Support: Up to 8 total (1 CPU baseplate + 7 Expansion/Remote).
  
• Onboard Port: 1 RS-485 serial port (supports SNP/SNP-X protocols).
• Power Consumption: 890 mA from +5 VDC bus.
  

Features

• Floating Point Math: Includes built-in support for real-number calculations, essential for PID loops and complex analog scaling.
• Expanded Communications: Unlike the CPU360, the CPU363 features a 15-pin D-type connector on the front of the module. This allows for direct connection to HMIs, programmers, or other serial devices while leaving the power supply port free.
  
• Configurable Memory: The 240KB of memory can be partitioned between program logic and register data depending on the requirements of the specific application.
  
• PCM/CMM Support: Fully compatible with Programmable Coprocessor Modules (PCM) and Communications Control Modules (CMM) for specialized networking (like Genius Bus or Ethernet).
• Battery-Backed RAM: Uses the standard Series 90-30 lithium battery (connected to the power supply) to maintain the user program during power loss.
• Diagnostic Indicators: Features OK, RUN, and I/O Force LEDs to provide immediate status of the controller's internal health and execution state.
