Momentum/Concept 2.6/Scan times

Hello All,

I have a customer who uses Modicon Momentum PLCs
programmed with Concept 2.6. The scan times on these
controllers is beyond anything I've ever seen in a PLC. Small
units with < 100 I/O with scan times > 200 ms.

I'm trying to find a document that lists instruction scan
times and the relative efficiencies of different languages in the Momentum.

For example, I know that these controllers are not the most efficient at doing floating point math.

I've done all of the searches that I know how to do. Can
anyone out there point me in the right direction?

Thanks,
