  • Wonderware Industrial Application Server (component of Wonderware System Platform)


If you receive an error message(s) stating that the “IDE requires a network connection to continue…” or “A local network connection could not be found…” when launching the Wonderware ArchestrA IDE or attempting to open a Wonderware InTouch managed application within a galaxy, it is recommended you install Microsoft’s Loopback Network Adapter.

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.
