Why are PLC Changes Risky?

A simple change like adding a new data field or adjusting a process parameter can require:

- PLC code modification
- Scripting edits
- HMI program updates
- MES system interface routine changes

System revalidation …and sometimes recharacterization or run-off

Why? Because non-deterministic logic is embedded in controllers:

❌ Testing is difficult
❌ Deployment risks downtime
❌ Rollback is non-trivial

So organizations respond predictably: Everyone avoids change.

Are your factories stuck because of custom automation code everywhere?

How come non-deterministic function blocks / AOIs aren't seperated facrory-wide?
