Legacy System Support Hub

Legacy Industrial Automation System Support For PLC, DCS And Drive Spares

Use this hub to keep older PLC, DCS, drive and monitoring systems searchable by platform, series and exact model before requesting RFQ support.

Legacy Support Path

Long-life automation systems need platform context before exact spare parts can be sourced.

Older PLC, DCS and drive platforms often stay in production for many years after new sales stop. DRIVEKNMS organizes legacy system support around installed platform, model family, replacement risk and RFQ-ready part pages.

Support Routes

Choose the legacy support route closest to the installed system.

Platform context

Installed platform identification

Start from the old controller, DCS, drive or monitoring platform before comparing exact model pages.

Lifecycle

Obsolete model sourcing

Use discontinued model, suffix and revision data to reduce wrong-part and compatibility risk.

Replacement

Replacement planning

Check whether a part needs same-family replacement, compatible alternative review or RFQ verification.

RFQ route

Mixed legacy RFQ

Send legacy model lists across PLC, DCS, drives and monitoring systems for one RFQ follow-up.

System Families

Continue into core system hubs when the installed platform type is known.

System route Legacy PLC support PLC-5, SIMATIC S5/S7, Modicon and other long-life controller platforms. System route Legacy DCS support TDC, CENTUM, INFI 90, Mark, Ovation and process-control card routes. System route Legacy drive support SIMODRIVE, MASTERDRIVES, ACS, Kinetix, IndraDrive and motion spares. System route Obsolete parts RFQ Use lifecycle context when the part is discontinued or difficult to replace.

Legacy Series Routes

Use older series pages when the platform family is already known.

Series PLC-5 16 matched models Series SIMATIC S5 2 matched models Series TDC 3000 Series 7 matched models Series Infi 90 3 matched models Series Mark V 5 matched models Series CENTUM VP 20 matched models Series Modicon Quantum 25 matched models

Legacy RFQ Checklist

FAQ

Legacy system support questions

What is useful for a legacy system support RFQ?

Send the old system family, exact model numbers, revision notes, quantity, destination and whether replacement alternatives are acceptable.

Can DRIVEKNMS support mixed legacy platforms?

Yes. Mixed PLC, DCS, drive and monitoring lists can be reviewed together when model numbers and installed-system context are provided.

Why not quote legacy parts directly from a checkout page?

Legacy parts often require condition, revision and compatibility review before quotation, so RFQ verification is safer than public checkout stock.
