Please see the Product Registration Policy (PD10026) for Private Labeling and Rebranding of existing registered products.
HART 5 Private Labeling
A HART 5 product with a DD (*.fms) registered prior to March 31, 2011 may be private labeled by exchanging the MANUFACTURER and DEVICE_TYPE codes. The DD source must be otherwise identical to the previously registered DD.
There is no private_label_code variable for HART 5 devices. The member who is private labeling must have a 1 byte manufacturer ID code.
