SCOPE
This User Manual provides information on how to install, configure and use the full range of
Maxiflex P3 Process Automation Controller CPU’s.
Note : This manual also applies to the Maxiflex A3e CPU (Maxilarm) which is based on the P3
CPU. The standard features are common to both CPU types. For specific Maxilarm functionality,
please refer to the Maxiflex A3 User Manual.
This manual does not cover the fundamentals of the IEC61131-3 programming languages, nor the
Omniflex ISaGraf Programmer’s Workbench. This information is available separately in the
manuals supplied with that product, but programming features specific to the P3 CPU’s are
included in this manual.
This manual covers the following product Models:

Introduction
The MAXIFLEX P3 & A3 range of Process Automation Controller (PAC) CPU’s is designed for
general industrial control applications including process control, PLC, telemetry and remote I/O
applications. These CPU’s combine powerful industrial network communications capabilities with
ease of use and powerful programming features.
All I/O and configuration data variables are automatically accessible through up to 65,000 Data
Interchange Registers in a single virtual “Data Interchange Table”, allowing the implementation of
Remote I/O systems “out of the box” without programming.
For local control and data manipulation, the Maxiflex P3 & A3 PAC CPU’s can be programmed in
one or more of the standard IEC61131-3 programming languages using the powerful Omniflex
ISaGraf Programmer’s Workbench.
Many other features such as a built-in real-time clock, battery backup for temporary dynamic data,
and a MODBUS (Master or Slave) or Conet/s equipped RS232/485 serial port are standard in
these products.

Powerful features such as automatic I/O module recognition and scanning, remote programming,
and a versatile Remote Data Subscription Service, all contribute to making the P3 CPU a “plug-
and-work” product that dramatically reduces system engineering time.
Following the ISO OSI 7-layer model, these CPU’s includes powerful inter-network routing
capability for retrieving data from the corners of the factory in very large, geographically spread-out
installations. This capability allows many dissimilar network types to be linked to create a seamless
factory intranet, quite often without the need to install special network cabling.
The MAXIFLEX P3-R CPU’s are designed specifically for redundant remote I/O and control
applications, where high availability is required in hot standby configurations.
