Communication problem between S7 toolkit and S7-200 [SP7: SP7 open (connect.vi) Error 62]

[Khan666]

Hello,

We have problems connecting the 243-1 module, error code: 62

We ensure that the PLC type selected in SP7 is correct, and the IP address settings of PLC and SP7 are also no problem and can be accessed from each other.

Screenshots of PLC and SP7 are available in the attachment:

And does somebody knows a solution?

The PLC settings (screenshot PLC.png) look good.

Is LabVIEW the only client trying to connect on that ethernet port of the PLC?

Can you please check the following:

Set Remote TSAP to 03.00, and try to run the VI "SP7 connect" with an PLC-type LOGO!8 instead of S7-200. Does this also lead to error 62?

Very happy to share
We set the TSAP to 03.00 on the PLC side, LOGO!8 on the PLC type on the SP7 software, and then it was connected smoothly. After testing the DI and M types of data read and write, there is no problem.
PLC settings see attachment.

Thanks for the feedback - we will consider to adapt the API for this problem for the next version.

The new version v2019.6 of SP7 (now available for download) incorporate that change for S7-200.
