Why the Automation EOL Wave Is Coming
PLC hardware lifecycles are shrinking. Production lines are running longer than product support windows. Between 2026–2028, many PLC, HMI, and communication modules will enter end-of-life or final build cycles — available today, gone tomorrow.
The threat is not technical — it’s supply.
When OEM stops shipping, lead time becomes indefinite, and factories either pay extreme aftermarket pricing or shut down until a compatible replacement is located.
Understanding this cycle now means staying operational later.
Platforms Expected to Enter High-Risk Phase
ControlLogix Older Generation (Pre-L7x Series)
Still widely installed in food, chemical and automotive plants.
EOL risk: High ｜ Final-run window narrowing.
Stocking directive: Secure extra CPUs + EN2T comm modules.
SLC & PLC-5 Systems
Legacy but still heavily used in brownfield plants.
EOL risk: Very High ｜
Recommended: Acquire last-run modules before pricing explodes.
PanelView Plus (Early runs)
Backlight & panel degradation + OEM phase-outs.
Suggested approach: Hold 10–25% spare screens per facility.
Kinetix, Motion, Drive Interface Cards
Spare availability drops quickly after final build.
Recommended: Capture surplus stock across multiple warehouses.
Why This Crisis Will Hit Fast
-
Semiconductor nodes are switching to newer architectures
-
OEMs shifting resources to smart controllers + CIP security
-
Warehousing no longer built for legacy product retention
-
Global aftermarket demand is rising faster than supply
When demand exceeds stored inventory, price inflation is immediate.
Replacement may cost 2–8× later — if available at all.
How to Secure EOL Hardware Before It Disappears
Step 1 — Run a Lifecycle Audit
Flag PLC-5, SLC, early ControlLogix and PanelView units first.
Step 2 — Build a Spare-Criticality Index
Score based on failure probability × downtime cost.
Step 3 — Buy EOL Units from Multi-Warehouse Supply
Multi-warehouse = higher probability of last-run inventory.
Step 4 — Maintain Firmware-Matched Backups
Spare hardware is useless without firmware parity.
Step 5 — Convert Major Lines to “Replace-Instead-Repair”
Repairs slow — replacements restore instantly.

Bottom-Line Forecast
The 2026–2028 period will become the most important lifecycle window for legacy automation hardware in the past decade.
Enter prepared, and the crisis becomes an advantage.
Enter late, and EOL modules will cost more — or not exist.
With TopAutoDevice multi-region inventory + Fast delivery, factories can secure last-run components before the market dries up.
