9.1.2
Principle of data exchange for PROFINET IO
Data transfer via PROFINET IO
The block diagram below shows the interfaces of the SIMATIC MV540 H CRANES camera that are
relevant for data transfer.
Figure 9-2
Note
Relevant bytes
• Bytes 1 to 31 of the "Send" user data interface are relevant.
• Only bytes 1 to 10 of the "Receive" user data interface are relevant.
After the camera has been switched on and a connection has been established to the controller
via PROFINET IO, a simple handshaking procedure is used. The camera continuously sends its
data as a result.
9.1.3
Assignment of the interfaces relevant to PROFINET IO
The camera has two different communication layers for:
• Camera (camera control/status byte):
General functions, such as "Run" or change program, are controlled on the camera layer. The
general status of the camera can also be queried on this layer.
