Features:
- Runs Series 90-30 logic on a 20 MHz 80C188XL processor.
- Combines RAM and Flash for working and retained program storage.
- Supports a modular installation containing up to five baseplates.
The faster processor targets applications that need shorter logic execution than earlier 10 MHz CPUs.
Flash storage gives the controller an onboard nonvolatile program option without a removable PROM device.
Expansion support lets the CPU coordinate I/O beyond the main baseplate through the standard rack bus.

IC693CPU340 Scan Execution
- Processor clock: The 20 MHz core advances Boolean logic faster than the earlier 10 MHz CPU class.
- Instruction mix: Math, messaging and I/O service add work beyond a basic Boolean scan.
- Program structure: Branching, subroutines and communication calls influence the final cycle time.
- Timing review: Machine sequencing should be validated with the complete application running.
IC693CPU340 Rack Expansion
- CPU baseplate: The processor starts the system in a modular Series 90-30 rack.
- Five-rack reach: Up to five total baseplates can participate in the controller arrangement.
- Expansion cabling: The bus path must follow the supported rack sequence without open intermediate links.
- Hardware map: Rack numbers and module positions must match the stored controller configuration.
IC693CPU340 RAM and Flash
- Execution store: RAM contains the active program and changing controller data.
- Retained copy: Flash can preserve a nonvolatile application image for recovery.
- Battery role: Backup power remains relevant for volatile values and the configured retention strategy.
- Change control: The online project and stored Flash image should be kept at the same approved revision.
IC693CPU340 Communication Options
- SNP service: The power-supply connector provides the standard programming channel.
- Network modules: Communications hardware can add protocols not built into the CPU.
- Configuration match: Each option module requires the correct slot assignment and software parameters.
- Power allowance: Communication additions must fit the baseplate supply budget.
