I have a device with MODBUS TCP security protocol, and like to control it with Labview, so the first step is to connect to the device.
As a newer to TLS,I try the demo example Connect to the TLS Server.vi to link the device, but it is lost for just having IP address (not hostname) to Start TLS.vi. Is there other way to connect the device?

It’s very unlikely that you would need TLS for a Modbus device. They usually use plain TCP/IP. However Modbus is not a very trivial protocol for someone starting with controlling devices from LabVIEW. It would be better to use the NI Modbus library or one of the alternatives out there.

I have connected to the device as no input to server hostname port and "None" to server certificate validation port of Start TLS.vi
