Description

The Protection Processing Module (PPM) serves as the

computational engine for the Orbit 60 monitoring system. It

extracts all machinery measurements for the protection

system and performs alarm determinations. The PPM

analyzes signals from transducers, generates measurements

and statuses and publishes them to other modules for data

collection and external communication.  Each PPM occupies a

single slot within the system.

Each PPM provides computational capacity for a large

number of sensors and can support typical monitored

machine trains. The PPM capacity is a function of the type of

processing required on each input. If the system requires

more processing than a single PPM can provide, additional

PPMs can be added to the system for complex monitoring

deployments.  For protection systems, redundant PPMs are

recommended.

The Orbit Studio Configuration Software provides a System

Utilization Calculator to evaluate the remaining capacity of

the PPMs in your system. If a PPM processing capacity

reaches 90%, a warning indicator is displayed in Orbit Studio

software, and it is recommended to add another PPM or two

PPMs if the system is redundant.
