Issue
What is the difference between an On-Demand Compare and a Timed Compare in the ProWORX NxT software?

Product line
ProWORX

Environment
ProWORX NxT

Resolution
The On-Demand Compare function finds differences in logic and configuration between a database and a controller or, between two databases.
The Timed Compare function finds differences in logic and configuration between a database and a controller. However, the Timed Compare does not compare two databases. Once configured, the Timed Compare repeats the comparison automatically at the interval you set, starting at the time you specify.
