I have an OPC Server (Kep) pulling tags from an AB 1769-L36ERM and a few different Koyo PLCs (450, 454).
On the HMI (FTV SE) there's one screen that's almost exclusively tags from the CompactLogix and one that's all Koyo. Both screens have the same update rate (0.1s). The values on the screen that is all CompactLogix seem to be much more instantaneous than the other.
Could this be caused by the difference in hardware? I would imagine the CompactLogix is more powerful than the DL454 and probably has a larger-bandwidth ethernet port which allows it to transfer data quicker.
