Product overview
3.1 What is SIMATIC TOP connect system cabling?
Design
System cabling with SIMATIC TOP connect always consists of the following components:
● The front connector module with one or more 16-pin male connectors for connecting cables
● One or more terminal modules
● One or more connecting cables with plug connectors at the ends
Fully modular connection
The fully modular connection for the system cabling comprises the following components:
● Front connector module
ET200M
● Connecting cables
● Terminal modules

The components can be combined to suit the application and connected with simple plug-in
connections. The terminal modules are used instead of conventional terminal blocks and act
as the interface to the sensors and actuators.
In addition to the terminal module versions with screw-type terminals or push-in systems, there
are also versions with LED signaling and signal conditioning, for example, from 230 V AC to
24 V DC.
Flexible connection
The flexible connection for the system cabling comprises a front connector module
connection to the SIMATIC S7-300/ET200M digital I/O modules. The front connector is already
wired with 20 or 40 single wires
modules directly to the sensors and actuators in the control cabinet.
