interrupt switch removes power only from that IOP card. Power is removed only while the switch is
activated.
WARNING
The loss of power to an analog or digital output IOP causes t
he loss of the IOP’s outputs to the
field connections. Analog output IOP outputs drop to a nonpowered state (-6.9%), and the
digital output IOP outputs are set to their off state.
The nonpowered state of the output IOPs should result in a safe condition for personnel, the
plant, and the process under control.
2.3 HPM Subsystem Overview
Major assemblies
The High-Performance Process Manager subsystem (HPM) is comprised of the major assemblies that are
described in the following subsections. Figure 1 is a view of a single cabinet containing a nonredundant
HPMM and identifies some of the High-Performance Process Manager assemblies. The
High-Performance Process Manager major assemblies are:

Left 7-Slot Card File (Slots 1 through 7)

Right 7-Slot Card File (Slots 9 through 15)

15-Slot Card File

IOP Only Card File (in PM/APM upgraded cabinets)

Input/Output Processors (IOPs)

Field Termination Assemblies (FTAs)

Power Systems
Card file types
Three types of card files can accommodate both High-Performance Process Manager Module (HPMM)
and Input/Output Processor (IOP) cards, or may have IOP cards only. The HPMM card set occupies slots
1 and 2 in both the Left 7-Slot and 15-Slot card files. The HPMM card set occupies slots 9 and 10 in the
Right 7-Slot card file. All card slots accept IOPs.
An older “IOP Only” card file may exist in a HPM cabinet that was upgraded to an HPM from a PM or
APM. This older card file cannot support an HPMM card set. It is restricted to IOP cards and optional
I/O Link Extender cards.
