Maxiflex P3e-R CPU
M1267C
Introduction
This Installation Guide is intended to aid the fitment of the M1267 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 P3e-R CPU is designed specifically for applications requiring PLC programming,
offering industry standard IEC61131 programming capabilities combined with powerful
industrial network communications features in a redundant configuration when paired with
another M1267B P3e-R CPU.
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. The M1267B is equipped with an Ethernet based Network
port for Supervisory communications, an additional Ethernet based Sync port for data
synchronisation with the paired M1267B CPU, and serial port (RS232/485) and a
programming port.
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).
Software Requirements
Omniset is the PC utility that is used to configure the unit.
Configuring the Realtime Clock(RTC)
1. Assemble the Maxiflex base as shown in Figure 1 with the M1267B fitted into the CPU slot
and a suitable Maxiflex PSU in the PSU slot
2. Connect power to your system.
3. Connect the M1831 programming cable between the COM port of your PC/laptop and the
programming port of the Maxiflex CPU.
4. Open Omniset and click on File->Connect->Maxiflex CPU TAB.
Select the GROUP Configuration->Ports->Realtime Data->Date/Time which is found in the left
hand pane. Change the RTC settings by pointing the mouse to the ITEM you wish to change
and clicking on the right mouse button and selecting the New Value option that pops up. Enter
you new setting when prompted. Refer to screen grab below.

Communications Protocol
Serial Port Dipswitch setting
Modbus Protocol (Slave device):
Transmission Mode: ASCII
Baud rate: 9600
Data bits: 7
Parity: none
Stop bits: 1
Address: see dipswitch
Switches 1-5: Modbus ID
Switches 6-8: Protocol
Switch 8 ON = Modbus default

Transmission Mode: RTU
Baud rate: 19200
Data bits: 8
Parity: none

Switches 1-5: Conet ID
Switches 6-8: Protocol
Switch 7 ON = Conet/s default
The default operation is to use the serial port for standard communications allowing the user to
get the CPU up and running quickly and easily both on the test bench and in the field. In this
case the Serial Port Dipswitch beneath the male, sub-miniature DB-9 connector has the above
default configurations. The serial port is also software configurable using the Omniset utility or
application program, but when switch 7or 8 of the dipswitch is turned ON, then the dipswitch

setting overrides the software configuration. To restore the settings to the software
configuration, simply set switch 7 or 8 of the dipswitch OFF.
Table 4: Serial Port Pinout
The M1267B P3e CPU allows jumperless conversion between RS232 and RS485
communications. By simply following the appropriate pinout of the serial port connector below
it is possible to connect the CPU in either mode without making any hardware or software
changes to the CPU.
