What Total Discontinuation means for you

The manufacturer has finished with the part. You may still find one through surplus or refurbished sellers, or in another site's stores, but that is not a supply chain. Knowing where your units are, and where a spare might be, is what shortens the stoppage when one fails.

How ECS defines Total Discontinuation · all four lifecycle stages

Before replacing an analogue module

With analogue I/O, the difficult part of a migration is often hidden in the configuration: signal type, range, scaling, resolution, isolation and any filtering used by the application.

We would capture both the hardware settings and the PLC scaling logic before choosing a replacement. That gives the commissioning engineer known reference values and avoids trying to recreate process calibration from a failed module.
