Data Resolution to the Cloud
Summary
See below for our information on our data resolution to the Cloud.
3rd Party Protocol
Many 3rd Party Devices allow Industrial Gateways to locally collect a large number of data points every second, however the Industrial Gateway itself is limited to uploading a maximum of 100 new datapoints every second to the Samsara Cloud. More than 100 separate data points can be collected, but the polling rate per data point will be reduced after 100. The maximum polling rate for 200 data points would be once every 2 seconds. Once per 3 seconds for 300, and so on.
