Emerson 4620 Using HPI-B

System Management Interface Based on HPI-B (Centellis 4620) User’s Guide (6806800D85A) 23

Using HPI-B

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.

This section describes those HPI-B features which the Emerson HPI-B implementation for the

Centellis 4620 environment does not support.

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.
