Get Siemens LOGO OBA7 data in Labview through Ethernet Port

[Grugh_Mike]

Please help me get the Siemens LOGO Status including Network ouput data to a Labview program.

Is there any Siemens OBA7 drivers in Labview.

Please Help.

Thank you in advance

It looks like the interface is basically a TCP connection. Does Siemens document the protorcol that they use? Perhaps with code samples?

hi,

i am also looking to communicate to a siemens logo! PLC 0BA7 via ethernet using labview. the LOGO! documentation doesnt say much about ethernet communication. i tried a simple labview code which i have attached here, error message shows the connection has been refused. i have set the LOGO! to slave mode with my PC as the master I/P but still get this error (see attached jpeg). i apologise in advance i am a relatively new to LabVIEW and TCP comms.

Hello,

i had the same problem. Try to use a IP-adress without zero´s. Like this 192.168.0.50 and the port 10001.

Hello Schwede,

Perhaps you can first try the ethernet connection using Siemens' software for Logo! on your PC. If the communication is successfully established there, then it should be possible to design the TCP VIs in LabVIEW to follow that configuration, as long as it follows the TCP standard. It is advisable to consult Siemens for more details on their ethernet communication.

On the LabVIEW side, a good start is to look at the example VI in Example Finder. Look for Simple TCP.lvproj. More details are available in LabVIEW -> Help -> LabVIEW Help -> "Using LabVIEW with TCP/IP and UDP".
