Data table

The data table window displays the data values for items in the data table file. The status bar shown at the bottom of the data table window contains the Status and Selection areas. You can:
  • Change the data table poll rate: right-click the grid and choose
    Properties
    .
  • Manually refresh the tag information: right-click the grid and choose
    Refresh
    .
  • Activate or deactivate the data table: right-click the grid and choose
    Activate
    or
    Deactivate
    .
Radix
shows how the data values are displayed (Binary, Octal, Decimal, Hexadecimal, or ASCII). To change the radix, click the drop-down arrow in the Radix column, and choose the desired radix.
Type
shows the data type for the tag.
Access Rights
 shows the External Access setting for the tag (set in Logix Designer application). It specifies the level of access (Read Only, Read/Write, or None) that external applications and devices have to tags.
Read/Write
External applications and devices have full access to the tag and can therefore read and change the tag's value.
Read Only
External applications can read, but cannot change, the tag's value.
None
External applications cannot read or change the tag's value.
For modules that do not support the External Access setting, the Access Rights is always shown as Read/Write. For more information, refer to the documentation for Logix Designer application.
In the status bar:
  • Status displays whether the data table display is active or inactive. If the data table is inactive, RSLinx Classic is not polling the processor for data.
  • Selection displays the currently selected OPC item (cell) from the data table.
