Harmoni is the most compelling platform for CNC job shops wanting to automate operator time tracking, program loading, and job data collection in a single hardware terminal. Not suitable where condition monitoring is a requirement.
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.
