Suffix Breakdown & Model Matrix

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Integration

The IC693CPU341P utilizes an 80C188 microprocessor operating at 20 MHz to maintain high backplane bus communication velocity across local expansion racks. Direct memory mapping channels I/O scan tables to CPU registers with minimal latency, supporting deterministic execution cycle rates. Integrated non-volatile Flash memory maintains full firmware flash compatibility, allowing program execution and parameter storage recovery without relying on persistent external power.

Frequently Asked Questions

Q: What are the backplane power supply limits for the IC693CPU341P?

A: The IC693CPU341P draws 550 mA at 5 VDC directly from the baseplate power supply bus rail. Hot-swapping is prohibited; the system power supply must be completely de-energized prior to hardware insertion or removal.

Q: How is programming and serial communication physically accessed on this CPU model?

A: The IC693CPU341P uses the 15-pin D-sub RS-485 port located directly on the baseplate power supply unit, natively supporting SNP and SNP-X slave protocols for connection to programming software or HMI devices.

Field Installation Guidelines

1. Power De-energization: Ensure primary supply power to the baseplate and attached expansion chassis is completely isolated prior to mounting or removing the module.
2. Chassis Seating: For embedded CPU baseplate models, verify that the CPU module is locked securely into its dedicated slot directly adjacent to the power supply unit.
3. Cable Shielding: Connect RS-485 serial communications cables using shielded twisted-pair (STP) cabling. Ground the cable shield at one end to prevent ground loop currents.
4. Serial Grounding: Connect the 15-pin D-sub connector shield drain wire to functional earth (FE) to preserve signal noise immunity in severe electromagnetic interference environments.
