Omniflex M1261F Installation Manual

Introduction

This Installation Guide is intended to aid the fitment of the M1261 CPU in the field. For
operating details of this product, refer to the Users' Manual. Please read this Installation Guide
first before installing this unit.
The Maxiflex P3 CPU is designed specifically for applications requiring PLC programming,
offering industry standard IEC61131 programming capabilities combined with powerful
industrial network communications features.
It is always fitted into the CPU slot of a Maxiflex master base, next to the PSU module. See
figure 1. It has one port which is a configurable serial port. This port has a DIP switch for
address and parameter settings.
RAM is battery backed so that application program variables are not lost on power down, the
battery will be connected if you have an Omniflex application loaded already. If you are
starting with a fresh CPU from stock the battery will need to be connected.

Hardware Installation Procedure

1. If the BATTERY is required then connect jumper located in the front of the module, just
above the DB-9 serial port connector. Remove paper strip which says PULL TO
CONNECT BATTERY. The Real time clock must then be set.
2. If the CPU is going to be programmed use Programming port cable M1831 which is
available as an accessory (Model No. M1831).
3. Plug the CPU into the CPU slot (as per Figure 1).
