Condition Monitoring Part Electrical Interface

Important - All wires and cables connected to input and output terminals shall
have a flammability rating VW-1, FT-1 or fulfill the requirements according to IEC
60332-1-2 or IEC 60332-2-2.

Communication Cable

For a length of up to 15 meters, it is recommended to use a pre-fabricated Ethernet
cable FTP type, CAT5/6. For a longer cable length, use S-FTP Ethernet cable CAT5/6.
Note that a CAT5/6 twisted pair (TP) Ethernet cable has maximum working distance of
100 m. If longer cable lengths are needed, fibre optic cables may be used along with
needed converters such as converters for fibre optic to CAT5 Ethernet and vice versa.

Data Communication

An IMx-M rack communications are compliant with the Ethernet standard 10/100 Mbit.
Each CMM + PRM pair has two Ethernet ports which work like an internal switch.

Ethernet Cable

The Ethernet TP cable on the back of each CMM + PRM slot is connected at one of the
standard Ethernet RJ45 connections, named ETH1 and ETH2. Both Ethernet ports
have auto detection of crossover or straight through Ethernet cable connection.
Basically, each CMM + PRM slot has a 2-port built-in Ethernet switch. Refer to
Panel section for the view of the terminals.
Table 4-1: IMx-M Ethernet connections
It is possible to connect a CMM + PRM slot in a daisy chain. The number of CMM + PRM
slots that can be connected in a single cable layout can be varied. However, it is
recommended no more than 8 CMM + PRM slots in a single cable layout in order to
minimize the loss of sensitivity.
For the behaviors and their corresponding descriptions of Ethernet LEDs, refer to
Condition Monitoring Module (CMM)

Hardware Configuration

When referring to DIP switch settings 0 means "Off" and 1 means ON.
