The Offline mode was designed for systems where a Driver needs to be configured at run time. This is the case when users simply do not know the type of connection or the parameters until the application is executing.

In Offline mode, all I/O Driver Tags fail (all writings and readings). The only Tags allowed are IOKit general Tags (N1/B1 equal to minus one and N2/B2 equal to zero). Although users can toggle a Driver between Online and Offline modes at run time, the following steps are needed:

1.Configure the Start driver Offline option on Driver's Properties Window Extras. This option allows a Driver to start in Offline status.

2.Configure the Driver parameters in a script in the application. This script can be executed automatically or according to a user's request.

3.Configure the Driver to Online mode.
