  • WirelessHART does not use TCP. That is, there is no TCP between the WirelessHART devices and the WirelessHART gateway. WirelessHART has a number of security measures such as encryption, authentication, sequence number, and key rotation etc. which are always on - i.e. you do not need to do anything special to turn it on.

    TCP is used between the WirelessHART gateway and the host (system). It can be secured using SSL per protocol e.g. HTTPS, Modbus/TCP secure, HART-IP secure etc.
  • Yes, this is what I ment.

    I have some questions:
    1) How can I make a regular TCP connection between the WirelessHART gateway and the host (system)? (Instead of Secure Tcp)
    2) How can I send an authentication details externally and not through the HartTalk program? Because I want to make a connection without the HartTalk.

    Thanks,
    Adi

    What is HartTalk? I am not familiar with this program. Please provide link to website

    For Emerson gateways use a web browser and go to Setup\Security\Protocols - there you can enable the application protocols you need

    Note that it takes more than TCP/IP to communicate. You need to use an applicaiton protocol like Modbus/TCP, HART-IP, EtherNet/IP, or OPC

    HART-IP is explained in these articles:
