What is SIMATIC TOP connect system cabling?

Introduction
SIMATIC TOP connect system cabling is an efficient way to connect the I/O modules (input
and output modules) of the SIMATIC controller S7-300 and ET 200M I/O modules. SIMATIC
TOP connect uses standardized connectors and reduces the wiring work required.
There are two types of connection:
● Fully modular connection:
for connecting sensors and actuators in the field.
The fully modular connection replaces the previously used terminal strips.
● Flexible connection:
for simple wiring inside the control cabinet.
Area of application
SIMATIC TOP connect allows you to wire actuators and sensors "locally" to one or more
terminal modules. Connection to the I/O modules takes place via connecting cable.
