I read that using rack optimization a single CIP connection will be used to transfer IO data from remote card to local card, provided its a digital card.
I was wondering if this applies to generic 1756 module?
Also, say in a hypothetical scenario I have (rack optimized):
Remote EN2T: 200ms RPI
Remote DI (1): 20ms RPI
Remote DI (2): 60ms RPI
Would the communication speed still be dictated by the EN2T card?
I did a few experiments with generic 1756 modules instead of digital input cards, and found that the above example's packet per second is affected by all three RPIs. I did a wireshark capture, and all three affected the comms speed. Disabling rack optimization significantly dropped the pps, so rack optimization is clearly improving comms speed.
Based on my understanding of rack optimization, I anticipated only the EN2T card to affect the pps. Can anyone clarify this observation?
Thanks in advance.
