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.
Pulsar is a credible choice for mid-size and large plants that want OEE across mixed and legacy equipment without opening a single controller. Buyers who need predictive maintenance, published pricing or a self-install option should look elsewhere.
