Using HPI-B
4.1 Overview
This chapter provides information which is necessary when writing applications that are based
on the Emerson HPI-B distribution. It lists limitations with respect to the HPI-B specification and
describes extensions which were added by Emerson.
4.2 Limitations
This section describes those HPI-B features which the Emerson HPI-B implementation for the
Centellis 4620 environment does not support.
4.2.1 Limitations with Respect to HPI-B Base Specification
The following limitations apply with respect to the compatibility with the SAI-HPI-B.01.02
specification. Note that these limitations apply to the current and also to all future Emerson HPI-
B releases for Centellis 4620 platforms. There are no plans to implement these features in the
future.

one is a read-only field containing the ManufacturerID (3 bytes). The second field (252
bytes) can be updated by the user. The Emerson HPI-B implementation of
saHpiIdrAreaAdd() does not support the creation of other types of Inventory Areas.
