9 PLC Upgrades That Cut Downtime by 40% and Actually Justify Their Cost

Firmware updates are no longer available. A single module failure means days of downtime while you hunt for a replacement on eBay or a secondary market that treats you like a scrapyard dealer.
The CFO wants to know why this costs $180,000 to fix when it "just switches things on and off." You want to know if you can limp along another year. Your controls engineer knows better but does not have the data to prove it.
