Wiring of analog modules for the SIMATIC S7-300 with SIMATIC TOP connect
An analog terminal module is available for wiring SIMATIC S7-300 analog modules with SIMATIC TOP connect. The following connection information must be followed when wiring.
Load voltage supply
In the front connector module, there are separate connections for the L+ and M load voltages. This allows you to connect the load voltage supply of the analog module either on the front connector module or on the connection module. The distance between the front connector module and the connection module can be up to 30 m.
Terminal assignment
The individual terminals are labeled alphabetically on the TPA terminal module. This makes it easier for you to assign the individual terminals on the analog module to the terminals of the connection module.
The tables show the assignment between the terminals on the analog module and on the connection module.
Assignment of 20-pin analog front connector module to the connection module
The upper socket of the front connector module is the connection for connection module 1, and the lower socket of the front connector module is the connection for connection module 2.

Shield connection
On the analog module, you can connect the shield of the shielded signal cable to ground via a shield connection element. On the terminal module you can connect the shield to ground via the shield plate. You can connect the shield of the signal cables or the round-sheath ribbon cable direct to the connection module. Secure a shield plate to the terminal module for this purpose before assembly. In the graphic you can see that the shield plate is on the rear of the terminal module and that the connection to the grounded DIN rail is made in this way. You connect the shield of the signal cables or the round-sheath ribbon cable with the shield connection terminals on the shield plate.
