Emerson 4620 Manuel D’Utilisation

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.

one is a read-only field containing the ManufacturerID (3 bytes). The second field (252
