is it possible to access the S7 1500 PLC with passwrod lock ?

[QuakeString]

when I try to access my running S7 300 plc without any kind of password, I can access it.
but I can't access my S7 1500 plc with password, can't access it.
is there any way to put password in connection string ?

I believe, though I'm not entirely sure, that the S7-1200 and S7-1500 support encrypted connections using TLS. Unfortunately, this library does not support TLS encryption. If you can't get rid of the password, an alternative would be to use the built-in OPC UA server capability of the S7-1500. Finding an OPC UA client that supports TLS encryption should be easier.
