Installing a Module

Precautions and Limitations

The BMXNOR0200H module may be installed in any of the positions in the rack except:

the positions reserved for the rack power supply modules (marked PS, PS1, and PS2),
the positions reserved for extended modules (marked XBE)
the positions reserved for the CPU in the main local rack (marked 00 and 01 for M580 and marked 00 for M340),

The following diagram shows a rack assembly including a M340 CPU (in this case a BMX P34 2020) and a BMXNOR0200H module:

discrete I/O module at rack position 1

counter module at rack position 2

available rack positions

extension module at rack position 8

NOTE: In a Modicon M340 system the total number of communication modules, such as BMX NOE 01•0 or BMXNOR0200H modules, cannot exceed two. The maximum Ethernet port for M340 system is 3 including the port on PLC. Therefore, a maximum of two BMXNOR0200H modules can be inserted in a M340 system.

NOTE: For Modicon M580 system module limitations, refer to chapter System Throughput Considerations.

Mounting Instructions

WARNING

MODULE DESTRUCTION - LOSS OF APPLICATION

Disconnect all power to the rack before the installation of the BMXNOR0200H module.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

To mount a module on the rack:

Step	Action	Illustration
1	NOTE: Before installing a module, take off the protective cover from the module connector located on the rack. Position the two pins on the reverse side of the module (at the bottom) in the corresponding slots on the rack.
2	Incline the module towards the top of the rack so that the module sits flush with the back of the rack. It is now set in position.
3	Tighten the mounting screw so that the module is held in place on the rack. Tightening torque: 0.4...1.5 N•m (0.30...1.10 lbf-ft).

WARNING

UNINTENDED EQUIPMENT OPERATION

Check that the mounting screw is securely tightened to ensure the module is firmly attached to the rack.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
