Upnp Template Language in the Delta V Workstation

Could someone explain to this old instrument engineer, lacking in IT terminology, what UTL functions (if any) reside within the Delta V software architecture?

It this something that is not affected by application level code and something within the operating system?

“UTL” meaning ”Upnp Template Language” and refer to details? Many thanks.

  David, UPnP is an Ethernet protocol developed for IoT type devices, such as Appliances and other devices that would exist in Internet connected architectures, as far as I can tell, and I am totally open to being corrected if I've over simplified this. UPnP stands for Universal Plug and Plan.
  
  This protocol is not used by DeltaV, though I don't know if the windows OS level plug and play follows this protocol for recognizing monitors, keyboards, and other devices connected at the OS level.
  
  When it comes to DeltaV software, Controllers, IO Nodes, EIOCs and such have a proprietary auto discovery, which sounds similar to UPnP, whereby new devices announce them selves via broadcast and are commissioned into the system at which point the pro plus assigns them their "identity" as selected by the user. That is they get an IP address on the network and their device Name, followed by a download of their configuration.
  
  DeltaV supports HART and Foundation Fieldbus Instruments which also have a discovery mechanism that allows a device to be detected and assigned its functions. This more so in FF which is a bus with multiple addressed devices. HART is a point to point implementation that uses a hardwired 4-20 mA signal augmented with digital communication. The device type is autosensed by the system once it is connected to a HART enabled Channel.
  
  WirelessHART devices are provisioned, meaning the device is assigned a name, a wireless Network ID and a Join Key which allows the device to join a mesh network and become available by name within the system.
  
  In the control system environment, we typically deal with IIoT, or Industrial Internet of Things, which is also referred to as Industry 4.0. The main protocol in use at this level is OPC UA, which has an adoption advantage over other protocols. Due to cybersecurity concerns and the criticality of IIoT applications, connection to the internet is not typically allowed, not without VPNs or other tunneling techniques to protect against outside threats.
  
  Anyway, you did not indicate what context your question is about. What are you trying to do that is leading you down this path about UPnP?

  Thanks for the rapid response Andre.

   

  The reason I was enquiring was my IT group were requesting a list of the software running on the Delta V workstations.  The query specifically was:

   

  “What software is installed on this machine?  Is it dedicated to AV or does it serve other UTL functions?”

   

  And my error, “UTL” referred to “utilities”. 

   

  Best Regards,
