For those kinds of speeds, you are best off using a ring buffer data structure (array of structures) in your PLC, with `head` and `tail` integer tags for the current subscripts into the array. Only those two tags would be subscribed. `head` would be updated by the PLC as entries are filled. `tail` would be updated by Ignition as entries are delivered to the consumer.

Use a timer at the desired slower pace to perform a bulk PLC read of the entries between `head` and `tail`, send them to the consumer, then update `tail`.
