Solving the Discontinued Hardware Crisis

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Facilities that have successfully extended Series 90-70 service life typically follow three disciplines: (1) maintain a minimum two-unit spare buffer for every critical I/O module type, (2) document firmware versions and rack slot assignments before any maintenance intervention, and (3) source replacement modules only from suppliers who can verify hardware revision compatibility. DriveKNMS operates within all three of these disciplines.

Condition & Reliability Assurance

Obsolete hardware sourced from secondary markets carries real risk. DriveKNMS applies a five-step qualification process to every IC697ACC701 unit before it is offered for sale:

• Step 1 – Visual and mechanical inspection: Board-level examination for physical damage, corrosion on edge connectors, and pin integrity on all I/O terminals.
• Step 2 – Electrolytic capacitor assessment: Series 90-70 modules manufactured in the 1990s contain electrolytic capacitors with a finite service life. Each unit is evaluated for capacitor bulging, leakage, and ESR deviation — the primary failure mode in aged analog circuitry.
• Step 3 – Firmware and hardware revision verification: The module's hardware revision is documented and cross-referenced against known compatibility matrices for Series 90-70 CPU firmware versions.
• Step 4 – Pin and connector corrosion check: VME backplane connectors are inspected and cleaned. Oxidation on gold-plated contacts is a common cause of intermittent faults in stored modules.
• Step 5 – Functional power-on test: Where test bench infrastructure permits, modules are powered and basic communication with a Series 90-70 CPU is verified prior to shipment.

Key Features for System Maintenance

• Drop-in replacement: The IC697ACC701 installs directly into any compatible Series 90-70 rack slot. No hardware modification is required.
• No reprogramming required: The CPU recognizes the module by rack position and hardware type. Existing ladder logic and I/O configuration tables remain intact.
• Avoids engineering reconstruction costs: Substituting a like-for-like module eliminates the need for control system re-engineering, I/O remapping, and factory acceptance testing — costs that accompany any platform migration.
• Preserves validated control strategies: In regulated industries (pharmaceutical, food & beverage, power), the control system validation record remains undisturbed when hardware is replaced with an identical module.

How do I confirm the unit is new surplus or quality-refurbished, not field-pulled scrap?
Every unit shipped by DriveKNMS is accompanied by a condition report documenting its source classification (new surplus or refurbished), the inspection steps completed, and the technician sign-off. We do not ship field-pulled units without full disclosure of condition.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.
