Gigabit Ethernet; Gige Vision - Siemens SIMATIC S7-1500 Manual

NOTE
Use of a USB camera
Use the USB interface only for testing and commissioning purposes.
Electromagnetic interference (EMI) on the supply cable of the 24 V DC supply of the module
can lead to failure of the connected USB camera. The value status (error byte, bit 5) signals
this state, allowing you to react accordingly with your user program.
For test operation of the USB interface, use a 24 V DC supply with max. 3 m cable length. In
this way, you minimize interference and prevent failure of the USB camera.
NOTE
TM NPU supports only "Super Speed" connections of the camera
Cable lengths > 2 m or the use of a USB2 cable prevent the camera from being connected
with "Super Speed". In such cases, the TM NPU refuses the camera connection.
4.1.4

Gigabit Ethernet

The Gigabit Ethernet interface is implemented as an RJ45 connection. A strain relief is not
present on the module.
Enable and disable the available Ethernet services in the parameter assignment:

• GigE Vision

• FTP client
• Debug web server
To simultaneously establish a connection to an Ethernet camera and an external device, e.g.
FTP server, connect the TM NPU to an Ethernet switch.
Use a Gigabit-capable switch to achieve the best performance.
4.1.4.1 GigE Vision
If your application is based on recording of camera images during productive operation, an
Industrial Ethernet camera is necessary.
This camera must support the GigE Vision protocol. The Ethernet interface serves as the input
for these cameras.
The TM NPU can connect to only one GigE Vision camera at a time.
Ensure that the TM NPU and only one other GigE Vision camera are in the same subnet.
NOTE
The GigE Vision camera can also be connected via an Ethernet switch. We strongly
recommend use of Gigabit-capable SIEMENS SCALANCE devices.
Required network settings
Make the required network settings, such as IP address, MTU size, etc. in the configuration
file named below: network.conf (Page 56).
