Overview
IO-Link master CM 4xIO-Link
The CM 4xIO-Link communication module is the IO-Link master,
for use in the ET 200SP distributed I/O system.
Features
•
IO-Link master as serial communication module with 4 ports
according to IO-Link specification V1.1
•
Module exchange with automatic data recovery without
engineering for IO-Link master and IO-Link device
•
Up to four IO-Link devices (3-wire connections)
can be connected to each IO-Link master module.
•
Data transmission rates COM1 (4.8 kBd),
COM2 (38.4 kBd), COM3 (230.4 kBd), automatic adjustment
to the transmission rate supported by the device
•
Port-by-port parameterizable diagnostics
•
PROFIenergy support
•
Parameterization of IO-Link parameters by S7-PCT V3.0 and
higher
Central data storage
If the communication module is pulled off the BaseUnit, part of
the electronic coding element will remain in the BaseUnit.
Stored in this part are the parameters of the CM 4xIO-Link and
the parameters of the IO-Link devices. When a new (not yet
parameterized) IO-Link master is plugged on, it will adopt the
parameters from the electronic coding element.
Connection
All type A0 BaseUnits can be used for the CM 4xIO-Link commu-
nication module, i.e. all variants of the BaseUnit (without/with
infeed, -AUX).
Configuration
Module integration
To integrate the module you need the engineering tool
STEP 7 V5.5 and higher or STEP 7 V11 TIA Portal.
Configuration
S7-PCT V3.0 and higher is required in addition for IO-Link
configuration.
The following diagram shows a PROFINET configuration in
which PROFINET ET 200SP and ET 200eco PN devices are inte-
grated with IO-Link masters.

The address areas for exchanging the cyclic data (process
values) are defined by IO-Link in the device view of the
PROFINET device.
