Abstract: In the mid-1990s, a group of vendors convened to address the growing concern regarding connectivity to the plant floor referred to as the Device Driver Problem. At that time, HMI and SCADA vendors were responsible for building their own driver libraries. This approach created great solutions when it included all the connectivity requirements that their end users would need, but incomplete solutions when it did not. The vendors were faced with a decision: they either needed to invest resource application-level functionality or extend connectivity.
