DevSetField

Sets new field data in the current record in a device.

Syntax

DevSetField(hDev, sField, sData)

hDev:

The device handle, returned from the DevOpen function. The device handle identifies the table where all data on the associated device is stored.

sField:

The field name, as a string of up to 10 characters. (The dBASE file format limits all field names to a maximum of 10 characters.)

sData:

New field data, in string format. Plant SCADA converts any other data type into a string before setting the data.

Return Value

0 (zero) if the data is successfully set, otherwise an error code is returned.
