Bandwidth usage – Sensor Access Technology

The default value is 50 msec, which means that the polling rate is every 50ms, i.e., 20 times a second, allowing up to 200 transactions per second. With a Waiting Delay of 500msec, the bandwidth usage is 2.8kbps (350bytes/sec) when no transaction is uploaded. The user may set each controller network with a different 'Waiting Delay'.
