I/O in a Terminal Services environment

The InTouch HMI cannot start I/O Servers in a Terminal Services environment. Depending on the sequence that view sessions start, you may need to use the IOReinitialize() function. All servers (I/O devices or view applications) must be running before starting an application that reads values from these servers.

Avoid receiving an "initializing I/O" error message when WindowViewer starts

1. Open WindowMaker.

2. On the File menu, select Configure, and then select WindowViewer.

   The WindowViewer configuration screen appears.

3. On the Preferences tab, in the I/O section, clear the Start Local Servers check box.
