Product Introduction
The PSCCM22AAN is a Control Communication Module built for the YOKOGAWA CENTUM CS 3000 distributed control system. It sits in the Field Control Station rack and handles V-NET / Vnet/IP communication between the controller and the rest of the DCS network. If you are maintaining a CS 3000 installation, this module is one of the critical communication links inside the FCU.
Replacing a failed or aging CCM quickly matters because the control station loses network visibility when communication degrades. Keeping a tested spare on hand avoids extended downtime during planned turnarounds or emergency swaps. This unit ships as new original or new surplus, depending on availability.
QA & Testing SOP
Every unit goes through a structured inspection before dispatch:
- Visual & PCB inspection: Check the connector pins, PCB solder joints, capacitors, and label integrity for corrosion, bent pins, or physical damage.
- Authenticity verification: Confirm YOKOGAWA branding, model marking, serial/lot information, and connector quality to screen non-OEM replacements.
- FCU rack power-on test: Install the module into a compatible CENTUM CS 3000 test rack and verify power-up behavior, LED indicators, and backplane communication.
- V-NET communication check: Confirm the module registers on the control bus and maintains stable link status with the FCU controller.
- Redundancy & hot-swap validation: Where test conditions allow, verify redundancy handover behavior and hot-swap readiness without disturbing adjacent slots.
- Anti-static packaging: Each module is packed in ESD-safe shielding bags with protective foam to prevent transit damage.
Installation Pitfalls & Guide
❗ Do not force the module into the slot. CENTUM CS 3000 backplane connectors are sensitive. Bent pins can damage both the module and the rack.
❗ Confirm redundancy status before removal. If the FCU is running dual CCMs, verify which side is active and which is standby. Never pull both communication modules simultaneously.
❗ Check V-NET cabling and terminators. A replacement module may power up correctly but still fail communication if the network cable, connector, or terminator is loose.
❗ Use proper ESD protection. Wear a grounded wrist strap and handle the module by its front panel or edges. Avoid touching exposed connectors.
Replacement steps:
- Pre-install: Verify slot position, redundancy status, and that the replacement model matches exactly.
- Removal: Loosen the retaining screws, disconnect V-NET cables if required, and withdraw the module straight out.
- Install: Align the guide rails, slide the module in firmly but gently, and secure the front-panel screws.
- Power-on test: Confirm LED status, V-NET link, and FCU communication. Run a brief redundancy test if configured.
Technical FAQ
Is the price negotiable for bulk orders? Yes. Pricing depends on condition, quantity, and lead time. New original stock and new surplus units are priced differently. Send your required quantity and we can work out a project quote.
What warranty do you provide? Standard warranty is 12 months from shipment for functional defects. This covers manufacturing or pre-shipment failures, not damage caused by incorrect installation or electrical surges.
Is this directly compatible with CENTUM CS 3000? Yes. The PSCCM22AAN is designed for the CENTUM CS 3000 Field Control Station. It is not a universal DCS module and should not be mixed with CENTUM VP or other product lines without confirmation.
Can I hot-swap this module? CENTUM CS 3000 I/O and communication modules generally support hot replacement, but you must confirm redundancy status first. Removing the active communication module without a healthy standby can interrupt FCU network communication.
Is this product still available given CS 3000 obsolescence? CS 3000 is a mature platform, and original factory supply is limited. We source tested new surplus and remaining OEM stock to support existing installations. If you need multiple units, it is better to confirm availability early.
