Siemens SIMATIC S7-1500 Manual page 17

When you use components in which the shield and ground signal are already connected to
each other, the power supply of the TM NPU should come from an electrically isolated 24 V
DC supply. Do not connect the ground of this 24 V DC supply to the functional earth (FE).
Note that the shield and the ground signal in the camera are connected to each other in the
recommended USB camera RealSense D435.
Ethernet interface
The Ethernet interface has been designed as an RJ 45 socket (X1 Port 1). The interface is
released for use as an input for Gigabit Ethernet Vision Cameras as of hardware function level
FS03 of the TM NPU.
We recommend the use of GigE Vision cameras of the type acA1300-60gc from Basler.
