All HART Manufacturer ID and Device Type codes are assigned by FieldComm Group.


NOTE – Manufacturer IDs and Device Type Codes require active IP licenses with FieldComm Group. This is typically obtained through Membership (most cost effective method), but may be purchased outright for 90% of the cost of membership dues. You can learn more by visiting www.fieldcommgroup.org/membership/membership
