Each “owd_xxx” element contains the device name (Name), family code (Family), ROM ID
(ROMId), health (Health), raw data used to obtain the data fields (RawData) displayed in hex
format, and a list of the data fields where the name of the data field provides the description.
Writing Data to 1-Wire Devices
To write data to a connected 1-Wire device that supports control commands simply make a re-
quest of
devices.htm
with the appropriate URL parameters. Below is an example:
devices.htm?rom=4300000200AD1928&variable=UserByte1&value=75
The URL parameters in the example are as follows:
•
rom
—the ROM ID of the device to modify, alpha characters must be upper case
•
variable
—the name of the variable to modify. The name is the same as the XML field
name, only XML fields with attributes of ‘
Writable=”True”
’ may be written, (e.g., <Us-
erByte....)
•
value
—the new decimal value to write to the 1-Wire device
