Good Morning,
we try to use the S7 connection library for Labview; we have an issue in the connect.vi: when we try to connect we have the following error:
Error 62 occurred at TCP Write in SP7.lvlib:Init_Adapter_TCP.vi->SP7.lvlib:connect.vi->exmpl_write_bit_array_in_DB.vi
Possible reason(s):
LabVIEW: Serial port overrun error.
=========================
LabVIEW: The system caused the network connection to be aborted.
We use Labview 2017 32bit on Windows 7. The plc is Siemens S7 400 on our private network.
Thank you
Best regards
Alberto Capogrosso

Hi,
we know of one issue when connecting to a S400:
The rack number of the CPU has to be 0 and its slot number must be 2, otherwise you cannot connect to the PLC.
This is currently on our list of things to fix.
Kind Regards

Update on this:
It's fixed in our internal build which currently undergoes final tests. Expect this one to be included in the upcoming release of SP7.
Kind regards,
Data Ahead
EDIT 2018-02-23: New package has been submitted to NI for release!
