Wonderware PacWest Tech Note 79 “How to install Microsoft Loopback Adapter on different operating systems”, written by Kurk Kembel, is available on the Wonderware PacWest website.
Wonderware Industrial Application Server uses the Suitelink protocol (a proprietary TCP/IP wrapper) and the NMX protocol (Network Message Exchange) to communicate with I/O devices and platforms/objects in the application galaxy. The Archestra Integrated Development Environment (IDE) uses the NMX protocol to communicate with and deploy objects to platforms in the galaxy (this requires a valid network connection for development and testing operations). In the absence of a network adapter or valid network connection, Microsoft’s Loopback Adapter may be installed to satisfy the Archestra IDE’s requirement for a valid network connection.
The Microsoft Loopback Adapter will prevent the Archestra IDE from closing in the event the development computer is using a wireless network connection that has intermittent connectivity losses.
