# Communications Monitor

The Communications Monitor is used to monitor how often Designer is reading and writing to external Devices, and is particularly useful when the Devices are GigE cameras.

For example, two GigE camera variables could be configured as tags, in the Tag Manager.

The tags' Update Rate Properties are specified (the default is 1000 msec).

When the project enters Test Mode, the Communications Monitor will display a row for each tag, with information on the number of reads and writes to the Device.
