DeltaV Virtual IO Module Network Ports

  • Product Family: DeltaV Virtual IO Module
  • Category: Technical Notes
  • SKU: IOD-4101, IOD-4102, IOD-4104, VIM-4201
  • The Virtual IO Module (VIM) provides intuitive network setup. However, on networks where a Network Firewall blocks certain Network ports, the communications suffer. The following is a list of exact port numbers that need to be opened on firewalled networks.

    Please refer to MYNAH Technologies DeltaV Virtual IO Module Network Gateway knowledge based article for a complete description of Virtual IO Module features, description and specifications, supported industrial ethernet protocols and firmware ordering information. The following table lists the ports necessary for communications with the VIM from VIMNet Explorer. These ports will need to be enabled for proper communications at each network firewall. The common firewall present on most computers is the Windows Firewall. For more information, please refer to the following article "Open a port in Windows Firewall".  For other network firewalls please contact your Network Administrator.
