RE:Time stamping -MVI-101S
If you look on pages 15 and 16 of the latest version of the MVI46-101S User's Manual, you will see the module can store hold the 10 most recent Events in it's communication queue. Any point configured as a Time-Stamped point will create an Event any time the value of that point changes. The time of that Event will be held in the designed registers in the queue. This is a First In - First Out queue; so, as new Events enter, they push the older Events off the queue. Once off the queue, there is no way to retrieve the data, as this module has no built-in archiving capability.
