More Information

Overview Manuals Processor Expansion Racks Backup Memory SNP Service

Features:

  • Uses a removable single-slot CPU format for modular Series 90-30 racks.
  • Extends a control system across as many as five baseplates.
  • Supports nonvolatile application copies in optional EPROM or EEPROM.
The processor can be exchanged independently of the baseplate after system power is removed.

Expansion capability separates I/O placement from the CPU rack while preserving one controller configuration.

Serial programming remains available through the power-supply connector rather than a front CPU port.

Apter Power assists with pricing and access to official manufacturer documentation for General Electric IC693CPU331 Series 90-30 Single-Slot CPU Module.

IC693CPU331 Processor Architecture

  • Module format: The CPU occupies one Series 90-30 slot and can be removed without replacing the rack.
  • Core device: An 80188 processor handles logic execution and controller housekeeping.
  • Application size: The available user space suits compact modular control programs.
  • Rack interaction: The CPU scans local and expansion I/O through the Series 90-30 backplane system.

IC693CPU331 Expansion Design

  • Main rack: The CPU begins the system in its primary baseplate.
  • Additional racks: Expansion hardware can extend the installation to the supported five-baseplate total.
  • Address discipline: Every rack and slot must correspond to the downloaded hardware map.
  • Bus completion: The final expansion connection requires the correct cable path and termination.

IC693CPU331 Memory Protection

  • RAM backup: The application remains in volatile memory while battery support is healthy.
  • PROM choice: EPROM or EEPROM can hold a separately prepared nonvolatile program image.
  • Maintenance copy: An external project archive protects comments and configuration not represented by raw memory alone.
  • Restart control: The selected power-up behavior determines how a retained program resumes operation.

IC693CPU331 SNP Maintenance

  • Connector location: The power supply exposes the serial service interface used by the CPU.
  • Protocol family: SNP and SNP-X support programmer access within the Series 90-30 environment.
  • Communication setup: Cable type, baud rate and workstation parameters must be aligned before connection.
  • Diagnostic session: Online access allows technicians to inspect status, references and fault tables.
Description
General Electric IC693CPU331 is a removable Series 90-30 single-slot CPU module that coordinates modular PLC systems with main and expansion baseplates.

A system built around IC693CPU331 can extend beyond the CPU baseplate, allowing distributed module placement while keeping processor replacement separate from the rack.

Communication with IC693CPU331 uses the SNP/SNP-X path exposed at the power-supply connector, so the CPU itself does not require a front serial connector.

Application storage for IC693CPU331 combines battery-backed RAM with optional EPROM or EEPROM, providing a controlled way to restore logic after maintenance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why will IC693CPU331 not enter RUN mode after a rack change?
Compare the IC693CPU331 hardware configuration with every installed baseplate and module, then clear only the faults whose physical causes have been corrected.
How many baseplates can be included in a IC693CPU331 system?
IC693CPU331 supports a five-baseplate architecture; verify rack numbering, expansion cabling, and termination across that complete arrangement.
Where should an SNP cable be attached for IC693CPU331 programming?
Connect through the serial interface on the Series 90-30 power supply associated with IC693CPU331 and match the workstation communication settings.
Can IC693CPU331 be replaced without changing the baseplate?
Yes. IC693CPU331 is a single-slot CPU, so power can be removed and the processor module exchanged while the rack remains installed.
How can a IC693CPU331 application be preserved during battery service?
Save the project externally and store a valid nonvolatile copy before disturbing the battery-backed RAM used by IC693CPU331.
Why does IC693CPU331 show faults after adding an expansion rack?
Check rack addresses, cable continuity, bus termination, and whether the saved IC693CPU331 configuration includes the newly installed rack.
What limits should be reviewed before adding modules around IC693CPU331?
Recalculate the +5 VDC load for IC693CPU331 and every installed module so the selected power supply remains within its rail capacity.
