The fully modular connection for connecting to the digital I/O modules of the SIMATIC S7-300 or ET 200M consists of modified front connectors, called front connector modules, preassembled connecting cables of various lengths, and terminal modules. Suitable components can be selected for the application in question and joined by means of simple plug-in connections. The terminal modules are used instead of conventional terminal blocks and act as the interface to the sensors and actuators.

Front connector module
Modified front connectors, called front connector modules, are available for connecting to the module. These are plugged into the module to be wired instead of the front connector. Many different front connector module versions, for digital I/O modules, 24 V 2-ampère modules or analog I/O modules. The connecting cables are plugged into these front connector modules.
Connecting cable
There are different versions of the connecting cable.
As a pre-assembled 16-pin or 50-pin round cable (shielded or unshielded) it is available in lengths up to 10 m.
When assembled, there are one or two insulation displacement connectors (female ribbon connectors) at both ends of the cable.
The connecting cable connects the front connector module with the terminal module.
Terminal module
The system has both digital and analog terminal modules for connecting the I/O signals. These are snapped onto the DIN rail. The terminal modules with basic or signal functionality are available in 1-byte or 4-byte versions.
Terminal modules are available for two different connection methods: with push-in or screw-type terminals. The potential can be fed in at the terminal module or at the front connector module.
If other voltage or power levels are required in the field, the terminal module for TPRo or TPOo output signals is used. For the TPRo terminal module, relays are used for the implementation. For the TPOo terminal module, optocouplers are used for the implementation. This converts the 24 V DC output signal simply and reliably to another voltage or power level. If 230 V AC or 110 V AC input signals have to be transmitted to the controller in the field, a terminal module with relay TPRi is available that simply converts the 230/110 V AC signal to 24 V DC. This means that there is always the same voltage level on the module side.
Use with optocouplers for the TPRo relay modules
If higher switching frequencies of the relay terminal module are required for the output signals, the relay can simply be replaced with an optocoupler (note technical specifications) in order to increase the switching frequency.
Shield plate
The shield plate is latched onto the terminal module for three-wire initiators or optionally onto the terminal module for analog signals and then snapped onto the DIN rail with the terminal module. With the shield connection clamps, optimal shield connection is achieved between the shielded round-sheath ribbon cable or the shielded field cables and the grounded mounting rail.

SIMATIC TOP connect for S7-300/ET 200M, fully modular connection
ENG_112695.XML
By using the fully modular system, the signal modules and the sensors/actuators can be up to 30 m apart, depending on requirements. Connection modules can be connected to the connecting cables. The I/O is connected to the connection module on site. The connection module is available in various performance ranges.
The potential infeed can be applied at the connection module or the front connector module.
ENG_112696.XML
With the fully modular connection of SIMATIC TOP connect, it is possible to wire the following components:

Note:
The product version of the modules can change, which in turn can change the Article No. of the modules.
