■
Application
•
The CM 4x IO-Link communication module enables an ex-
change of data with up to 4 external IO-Link devices through
one three-wire cable each.
•
Control can be flexibly adapted to the communication part-
ners using the comprehensive parameter assignment options.
•
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.

Design
Supported BaseUnits (BU)
All BUs of the A0 type are available for the CM 4x IO-Link
communication module.
Load group formation
A light BU isolates the self-establishing internal voltage buses
(P1, P2, AUX), thus opening a new load group. A load group's
supply voltage must be fed in on this load group's light BU.
A dark BU passes on the supply voltage of the adjacent light BU
on the left through the self-establishing voltage buses P1, P2
and AUX. Therefore, a supply again is only necessary at the fol-
lowing light BU on the right. Setting of a further light BU is always
necessary if
•
a new load group is to be formed (for example, to isolate the
supply voltage from module groups) or
•
the maximum simultaneously required current of the load
group exceeds the permissible limit of 10 A.
Color coding of terminals
The potentials at the terminals of the BaseUnit are defined by the
inserted I/O module. To avoid wiring errors, the terminals' poten-
tials can be optionally identified by module-specific color-coded
labels. The color-coded label matching the relevant I/O module
is defined by the I/O module's color code CCxx. This color code
is also printed onto the front of the module.
The color-coded label with the color code CC04 must be used
for the "CM 4x IO-Link" communication module.
In the case of BaseUnits with the additional ten internally jum-
pered AUX terminals, these can also be color-coded with color-
coded labels. Color-coded labels are available in red, blue and
yellow-green for the ten AUX terminals.
Labeling
Labeling strips
Labeling strips can be inserted into the front of the interface or
I/O modules and can be labeled individually via STEP 7, macros,
etc. A special additional support is not required. They can be
replaced easily with the component as necessary.
Reference identification labels
Reference identification labels enable easy equipment identifi-
cation (e.g. in accordance with EN 81346). They are simply
plugged onto the required component (interface module,
I/O modules and BaseUnits) and can thus be replaced easily
with the component, whenever required.
The following labeling components are available for selection:
•
Film labeling strips, light gray, roll with 500 strips,
pre-perforated, for thermal transfer roll printer
•
Film labeling strips, yellow, roll with 500 strips, pre-perforated,
for thermal transfer roll printer
•
Cardboard labeling strips (180 g/m
2
), light gray, ten A4 sheets
of 100 strips each, pre-perforated, for laser printer
•
Cardboard labeling strips (180 g/m
2
), yellow, ten A4 sheets of
100 strips each, pre-perforated, for laser printer
•
Reference identification labels, white, ten mats of 16 plates
each, for thermal transfer card printer or labels
System-integrated shield connection
A shield terminal that can be fitted quickly and easily is available
for space-saving and EMC-optimized connection of cable
shields. It consists of a shield connection element and a shield
terminal that can be plugged onto the BaseUnit for each module.
Low-impedance connection to functional ground (DIN rail) is
carried out by the user without additional wiring
