The HART 275 Communicator was discontinued by its manufacturer, Emerson Process Management, in 2004 and spare parts support ended in 2007. Given the large number of 275 communicators still in use, the HART Communication Foundation (HCF) will continue to offer programming services for the 275 handheld.
The last DD's for the 275 were published in June 2006. However the HCF can program a new mix of devices on the module.
The HCF provides services to upgrade Device Descriptions in 275 HART Communicator memory modules at a cost of $400 per module. Anyone requiring these services should contact Irina Kadukova at the HCF.
