Honeywell December 2020
HPMM functionality
The High-Performance Process Manager Module (HPMM) provides:

Communications with the Local Control Network (LCN) Network Interface Module (NIM) through
the Universal Control Network (UCN)

A Communications processor ( Motorola 68LC040)

Communications through the I/O Link Interface with Input/Output Processors (IOPs) and I/O Link
Extenders

A Control processor (Motorola 68040)

Separate and shared memory for the Communications and Control processors

An I/O Link processor (Motorola 80C32) with SRAM

HPMM redundancy control
HPMM card/module types
The HPMM is composed of two card types and a UCN interface module that mounts in the 50-pin
connector below the High-Performance Communications/Control card in the first left-most card file slot.
The cards and the module are described in the following table.
Table 2 HPMM Card/Module Types
Card/Module Type Function
High-Performance Comm/Control
Card Consists of a Communications (Comm)
processor, Control processor (Control),
separate and shared RAM for the processors,
interface to the HPMM Global bus on the
backpanel, TBC interface to the HPM UCN
Interface module, redundancy interface to
another HPMM, and front panel LEDs and a
four character alphanumeric diagnostic display.
High-Performance I/O Link Card Consists of an I/O Link processor, SRAM
through which the processor communicates
with the Communications/Control card, an I/O
Link driver/receiver interface, and a +24 Vdc to
+5 Vdc power converter that pr5 Vdc
for both HPMM cards and the HPM UCN
Interface module.
HPM UCN Interface Module Consists of 5 Mbps IEEE 802.4 compatible
MAP carrier band modulator/demodulator
circuitry that provides the interface with the
Universal Control Network (UCN). Logically
provides redundant UCN cable selection
(transmit on both, receive on the selected
cable) through redundant UCN cable
driver/receivers.
ESD HAZARD
It is important that you wear a properly connected Electrostatic Discharge (ESD) wriststrap
while touching or handling HPM components.
