Overview

Wiring of SIMATIC S7 I/O modules with the sensors/actuators is

a significant factor with respect to time/cost overhead, config-

uring, control cabinet installation, procurement and ease of

service.

With SIMATIC TOP connect system cabling, it is simple

and quick to establish a reliable connection for your

SIMATIC S7-300/400.

With the TIA Selection Tool, a mouse click is all that is required

to configure the connection from the SIMATIC S7 module to the

I/O. The program automatically checks for plausibility and

generates a parts list for the selected connection components

that can then be ordered in the Industry Mall.

Design

The flexible connection lets you quickly connect sensors and

actuators inside the control cabinet with the SIMATIC S7-400.

The flexible connection consists of:

• Front connector with screw-type or crimp connection

• Front connector with fixed single cores

• Single cores also available with UL/CSA-certified cores

The blue wires are numbered sequentially and can be routed

direct to each element in the control cabinet. The numbering of

the single cores corresponds to the coding of the front connector

contacts.

In comparison to conventional single wiring, there is a cost

saving of 50% for assembly, since the single cores that have

already been checked on the connector are fixed.

Thus no complex pre-assembly of up to two times 46 single

cores per module is necessary.
