Plex is the right choice for mid-market discrete manufacturers wanting machine monitoring as part of a broader cloud MES/ERP investment — particularly in automotive supply chain environments where Plex has deep vertical expertise.
Fanuc MT-Link i is the right choice for Fanuc-centric shops that want OEM-native FOCAS data with no middleware layer, and also need to pull in third-party machines via OPC UA or MTConnect. The legacy CNC support and 1-to-2,000-machine scalability make it viable across a wide range of mixed-equipment fleets.
