Wiring of analog modules for the SIMATIC S7-400 with SIMATIC TOP connect

An analog connection module is available for wiring SIMATIC S7-400 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 load voltage L+ and M. 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 connection module TPA. This makes it easier for you to assign the individual terminals on the analog module to the terminals of the connection module.

In the table, you can see the assignment between the terminals on the analog module and on the connection module.
