Write Device Identification VI

Installed With: LabVIEW

Writes Modbus object information stored on the device. This can include basic information, like manufacturer, additional standard items, or model-specific extended items. This function may take a large amount of time to execute, as it requires the transfer of a large quantity of binary data. Even on TCP/IP, this function is limited by the maximum defined size of a Modbus protocol data unit. If a slave supports objects, it is required that it stores information for VendorName (0x00), ProductCode (0x01), and MajorMinorRevision (0x02). The standard device data model provided by this library accepts any object request and can store any objects.

objects accepts Modbus objects. These objects consist of a numeric identifier and a string of data. VendorName (0x00), ProductCode (0x01), and MajorMinorRevision (0x02) are required to exist if a data model supports objects.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
