Control panel tip

Quick and easy control cabinet wiring with SIMATIC TOP connect - benefit from our expert tips
Your fast way to the mall


System cabling - the fully modular connection for your control cabinet

To ensure that electronic systems function and are available at all times, their individual components must be connected to each other reliably and without errors. Instead of the conventional complex and error-prone individual wiring, e.g. with terminal blocks, there is SIMATIC TOP connect system cabling.


Various connection concepts are available: the fully modular connection based on the modular principle, the flexible connection with bundled individual wires or the connection with the universal connection cable. Find out here how these concepts can be implemented quickly and easily in practice.

Your Benefits

Error-free and reliable wiring inside and outside the control cabinet increases system availability.

·       Entirely fault-free wiring

·       Minimum wiring outlay

·       Less time for wiring, modifications and troubleshooting

Fully modular connections

Fully modular connections simply, quickly and securely link sensors and actuators in the field to a SIMATIC S7 or distributed IO devices. The connection consists of front connector modules for the S7-1500 and S7-300, the ET 200MP and ET 200M, attachable connecting cables and terminal modules to replace conventional terminal blocks, and also permit voltage and performance adaptation.

The flexible connection

The flexible connection enables sensors and actuators mounted in the control cabinet to be connected to the SIMATIC S7 more quickly and easily. To achieve this, the front connector is prewired for connection to the digital IO assembly with 20 or 40 individual wires. The clearly labeled individual cores at the other end of the wire bundle can be routed to any element in the control cabinet.

Universal connecting concept

The unshielded universal connecting cable is available in lengths of 0.5 to 2 m for a wide range of control cabinet concepts. It is used to join the standard connection on SIMATIC or LOGO! devices with the SIMATIC TOP connect.
