Description
The Schneider Electric PCD984785 is a slot-mount central processing unit designed for Modicon Quantum automation platforms. Installed directly into a single rack slot, the module executes legacy 984 ladder logic programs with fast scan performance while receiving operating power straight from the backplane bus assembly.
Logic Processing and Memory Architecture
The processor hosts execution logic for standard 984 ladder instructions, providing a migration path and maintenance option for legacy industrial control setups. To safeguard operational data against total power loss, the PCD984785 stores its executable program and control configuration within onboard non-volatile flash memory, eliminating the requirement for external battery backup systems.
Communication Interfaces and Backplane Power
The module features a single integrated Modbus serial port on the front panel, enabling direct communication with programming terminals, supervisory control software, or human-machine interface (HMI) panels without extra interface cards. Operating power is sourced directly from the Quantum backplane interface bus, simplifying rack wiring and power distribution.

- Secure the module retaining mechanism to prevent backplane connector strain.
- Connect the serial programming interface to the front panel Modbus port.
Frequently Asked Questions
Q: Does the PCD984785 support hot-swapping while the Quantum rack is powered? A: No. The rack must be powered off prior to installing or removing the CPU to prevent electrical damage to the backplane bus connectors and module electronics.
Q: How is programming logic preserved during a total power failure? A: The module stores its control configuration and program logic in non-volatile flash memory, maintaining code integrity without requiring battery power.
