Vision function blocks now ship inside mainstream PLC firmware, forcing a real architecture decision: embed inference in the controller or keep it in a dedicated smart camera. Here’s how to actually choose.

OPC UA FX over TSN has moved from working-group slideware to certified servo drives, I/O blocks, and cobot controllers. Here’s a practitioner’s framework for deciding whether to pilot it now or wait a hardware generation.

PackML, PLCopen motion states, and OPC UA companion specs were each designed by different communities solving different problems — and stitching them together on one machine now surfaces a real mapping gap. Here’s how to close it before it corrupts your OEE data.

Ladder logic doesn’t fail loudly — it fails by making every new machine variant slower to build than the last. Here’s how to audit an existing codebase and decide what actually deserves a rewrite in structured text and OOP.

Higher-payload, longer-reach cobots are quietly invalidating the risk assessments behind many “collaborative” cells. Here’s a practical framework for re-checking your assumptions before you re-tool.

Standardizing motion code on PLCopen function blocks genuinely reduces cross-plant maintenance pain, but it doesn’t erase vendor lock-in — it just moves the lock-in down to the drive parameter level. Here’s how to think about the migration honestly.

Vision function blocks are now native in TwinCAT, TIA Portal, and FactoryTalk, which means the old default of “just buy a smart camera” needs a real decision framework. Here’s how to think about it.

PLCopen’s safety motion function blocks promise to unify safe torque off, safely-limited speed, and safe direction logic across platforms — but the real work now is deciding where that logic should live, and proving the response times before you ever run a pinch test.

Siemens has quietly made TIA Portal a genuinely collaborative platform, but most shops still engineer like it’s 2012 — one laptop, one project file, and a lot of hope. Here’s how to know when it’s time to move to a real multiuser setup.

Siemens, Rockwell, and Beckhoff have all put generative AI into their PLC IDEs, but none of them have handed plants a review process to go with it. Here’s how to build one.
