Description
Product Introduction
The ABB PM665 3BDS005799R1 is a PowerPC-based processor module for the Advant Controller 160 platform, serving as the central control unit in Advant OCS systems. It executes AMPL application programs, manages I/O via S600/S800 systems, and supports hardware redundancy for critical processes.
This controller includes an integrated redundancy voter, high-speed link for CPU synchronization, and a dedicated speed input for rotational monitoring. With 1 MB application Flash and 64 MB SDRAM, the PM665 handles complex control strategies while maintaining deterministic cycle times down to 2 ms. It requires Advant Controller 160 Master Software Version 2.2 and is commonly deployed in power generation, pulp and paper, and chemical processing plants.
Frequently Asked Questions
Q: Does the PM665 support hot-swapping in a redundant configuration?
A: Yes, but only in a properly configured redundant CPU pair. In redundant mode, the standby PM665 can be swapped while the primary remains in control. However, you must follow ABB’s prescribed switchover procedure and verify that both CPUs run identical firmware and application versions. Single-CPU configurations do not support hot-swap.
Q: Is this model obsolete? Are there direct replacements?
A: The PM665 remains the high-performance CPU for Advant Controller 160 Version 2.2 systems. It supersedes earlier modules like the PM645 for applications requiring redundancy and speed input. There is no drop-in replacement outside the Advant 160 family—migration to AC 800M requires a full system redesign.
Q: Will I lose my application program if I replace this module?
A: The application resides in the module’s 1 MB Flash PROM. If the new PM665 is blank, you must download the program from your engineering station. Always archive the AMPL project (PCPGM) and parameter files before removing the old CPU. In redundant systems, synchronize both CPUs before taking the old unit offline.
Q: Are these panels factory-new or refurbished?
A: Units labeled “New Original” are unused, factory-sealed surplus stock from decommissioned projects or distributor overstock. They are not refurbished, reworked, or open-box. Each module retains original ABB labeling, serial numbers, and packaging. For audit trails, request the customs declaration and packing list from your supplier.
Q: What is the warranty coverage and typical lead time?
A: Standard warranty is 12 months from shipment, covering manufacturing defects and DOA failures. Lead time for in-stock items is 1–3 business days domestically; international shipments may take 5–10 business days. Confirm exact terms, including RMA process, before purchase.
Q: What are the most common configuration mistakes with this CPU?
A: Three issues recur in the field: (1) mismatched firmware—ensure both CPUs in a redundant pair run the same Master SW version (2.2); (2) incorrect Com B settings—this port is MODBUS slave only, so don’t configure it as master; (3) neglecting the high-speed link termination—missing or incorrect termination resistors cause synchronization faults in redundant setups. Photograph DIP switch and jumper settings before swapping modules.
