DevicePollConfigEntry
This component configures device-level polling for consecutive proxy points, where one or more of these components may be
under the DevicePollConfigTable (
Device Poll Config) slot of a client ModbusDevice. Properties specify the starting Modbus address and number of points to poll.

You access these properties by expanding in the Nav tree.
| Property | Value | Description |
|---|---|---|
| Enabled | true (default) or false |
If set to false, associated proxy points use individual point polls instead.
|
| Start Address | additional properties | Refer to Start Address. |
| Data Type | drop-down list | Selects the location of the data in the slave device. Coils store on/off values. Registers store numeric values. Each coil or contact is 1 bit with an assigned address between 0000 and 270E. Each register is one word (16 bits, 2 bytes) as well as a data address between 0000 and 270E. |
| Consecutive Points to Poll | number from 0 to 9999 | Indicates how many points to poll beginning with the Start Address.
|
| Read Group Size | number (1 or 2) (defaults to 1) | Usually 1 unless all data items are 2-register types (float or long values), although a 1 works the same, provides consecutive points to poll is really consecutive registers. |
| Read Status | additional properties | Reports a numerical Error Code (0-2), and a corresponding Error Description.

Start Address
First data item address, including format and numerical address.
| Property | Value | Description |
|---|---|---|
| Address Format | Hex (default), Decimal, or Modbus | Selects the format of an address used to automatically configure unique register addresses for the device’s points. The driver merges this address with the point address. |
| Address | text | Defines the base address to use. |
