On Monday September 26th 2022 we released an updated version of our device driver that adds OPC UA functionality and data output to SQL Databases to machines equipped with MTConnect Adapters for instance from Mazak, Okuma or Haas. The update fixes issues and adds additional configuration options.
FIG.1: MTConnect machine monitoring
Problem: Some MTConnect Adapters occasionally output new ITEM|VALUE data blocks within milliseconds. This creates an enormous amount of simultaneous reading events in CNCnetPDM that impact performance or, with multiple machines, lead to restarts of the service.
Solution: The updated driver allows to limit reading events performed by CNCnetPDM to one per second while still collecting data packets even if received in such fast intervals.
