GT MTConnect Lite:
This version of the app enables spindle speed monitoring of a CNC machine that supports MTConnect. In order to use this app, the MTConnect webpage of the machine should be accessible to the smartphone/tablet; meaning that the device and machine should be both connected to the internet or be on the same local network.
GT MTConnect Pro:
This version of the app, in addition to displaying the current status of the machine, demonstrates historical charts related to the spindle speed (machine utilization) for the past 60 minutes, 24 hours, 30 days, and 12 months. This app requires a Google Scripts Web App ID in order to read the stored data from Google Sheets. A sample machine is added to the app to demonstrate how it works.
