Fitting the energy cable 5 x 1.5 with a power plug PRO
Introduction
The next section explains the individual steps assembling an energy cable with a power plug
PRO.
Note the information in the assembly instructions of the plug.
Connector pinout
An IE M12 plug PRO / IE FC M12 plug PRO with the pinning as shown in the following table
must be connected to both ends of the IE FC cable.

The signal assignment in the table corresponds to the pin assignment of the 4-pin
10/100BaseTX M12 socket of SCALANCE X208 PRO.
The pin assignment of the M12 socket of a network component on the other hand is as
follows:

The difference is that the send pin at one end must connect to the receive pin at the other
end. With straight-through cables, this is only the case if the connector pin assignment is not
the same at both ends. With devices that have autocrossing, a transmission would work
even if the pin assignment was the same.
