The redundancy Cross Transfer data takes up significant CPU time. Given you are using PlantPax there will be a signficant amount of data in a random fashion which is poor for redundancy. I haven't used the redundancy for years but remember there being a formula in the manual for the crosss transfer time. ...

The web browser provides that information for the L8 series. You need to have it enabled within the controller.

There is no such feature. With Rockwell you can have much longer rungs and therefore you are less likely to need the feature anyway. Your only alternative is to create an extra coil. I find the long rungs in Rockwell result in more readable code.

The only real benefit I see is the reduced execution time. Since I only use the fast CPU's now I don't use alias, they can only be changed via a download or messing around with temporary tags.

You would need to maintain the XIC->OTE to maintain the consistency. In the past I would have the alias tag reference say TAG1_Raw, for the XIC, and TAG1 for the OTE. Then if you re-assign the hardware point you just change the alias to TAG1_Raw.

In the older processors alias tags used less CPU power than a direct refence tag. In a direct reference tag the CPU has to calculate offsets from the base tag, in the same way it calculates offsets into arrays, which takes time. With the new high speed CPU's (1756-L8 and alike) the CPU time becomes far ...

The update has reduced CPU usage in Version 14, although still higher than version 13. Has anyone had issues with Version 15?

I have had a similar issue when updating from 13 to 14 with a less sophisticated display. The impact seems to be different on different hardware. I have the same application running on two PC's the three year old PC with Windows 10 is ok. The brand new top end Dell Precision workstation tops out two ...
