Configuring a device for polling
Data polling in a client device may be improved by configuring the use a single message to poll consecutively addressed values.
This reduces network messaging traffic. After adding all proxy points under a device, configure the device for polling. Typically,
this improves polling response due to fewer messages to get the same amount of data.
Prerequisites: You have created the device and added proxy points. Device polling should be configured until after proxy points
are created, and typically already receiving values from (individual) point polling.

- Double-click the ModbusAsyncDevice, ModbusTcpDevice, or ModbusTcpGatewayDevice in the Nav tree and expand the

- Configure the
Start AddressandConsecutive Points To Poll. - To organize points, add child DevicePollConfigEntry objects manually in this container or (optionally) use the container’s right-click action:
