Tech Note 18: Configuring Automatic I/O Failover in InTouch 9.5
The InTouch 9.5 HMI provides significant enhancements that result in improvements in both operational and engineering productivity. One of these enhancements reduces engineering development times by providing a one-click option for I/O Failover, which enables you to automatically switch I/O servers when I/O communication fails. Users can configure I/O server switching via the graphical user interface (GUI) in WindowMaker. Script functions are also provided to further extend the I/O communication failover features.
