■
Overview
CM IO-Link communication module
•
30-mm-wide CM IO-Link communication module
•
For connecting up to 4 IO-Link devices in accordance with the
IO-Link Specification V1.0 and V1.1 and Port Class B
•
The IO-Link parameters are configured by means of the Port
Configuration Tool (PCT) with version V3.2 and higher.
■
Application
The CM IO-Link communication module supports data
exchange between up to four IO-Link devices.
IO-Link devices (e.g. sensors) with a class A port are intercon-
nected by means of a 3-wire cable. IO-Link devices that require
an additional supply voltage and have a class B port (e.g.
actuators) are interconnected by means of a 5-wire cable.
Since IO-Link is compatible with standard sensors, commer-
cially available sensors compliant with IEC 61131 Type 1 can
also be operated on the IO-Link master.
The 30-mm wide I/O modules are ideally suited for use in
extremely confined spaces. They have adjustable parameters
and diagnostic functions and can therefore be flexibly adapted
to individual process requirements.
The following IO-Link masters are available:
•
CM 4xIO-Link communication modules, 4XM12
■
Design
The I/O modules have a screw mounting hole at the front and
side, and can be mounted in any position. As a result, they are
extremely flexible to install on either a level surface or on alumi-
num mounting rails using sliding blocks.
The CM IO-Link communication module features:
•
A backplane bus connection (Ethernet connection) with
M8 connection system for connection to an interface module
or other I/O modules
•
A power supply connection with M8 connection system
with loop-through
•
LED display for port status
•
LED display for channel status in SIO mode
•
LED display for module status (DIAG)
•
LED display for load voltage 2L+ (PWR)
•
Labeling plates for channel, module and slot identification
•
Integrated cable tie holder
•
Meaningful module inscription on front panel:
- Plain text marking of module type
- Interface marking
- LED label
•
Meaningful module inscription on side panel:
- Article number, function level and FW version
- 2D matrix code (Article No. and serial number)
- Pin assignments of all interfaces
Labeling plates for channel, module and slot identification are
supplied with the modules. These labeling plates can be in-
scribed using commercially available inscription machines.
