CITECT HISTORIAN

I think the best will be to ask to the local Schneider Office

he doesn't know it. he told me that replace VJH with CT. is correct? I think the reference order code same worldwide.

Are you looking to buy/order Citect Historian?
I don't think is still being sold any more, i know its longer being actively developed since 2016 and customers are advised to use AVEVA Historian instead which works with CitectSCADA as well

I'm not sure about worldwide sales of Citect Historian, but in my part of Europe it is no longer possible to buy licenses. Not even for existing sites, which is not really customer friendly in my opinion.

Our local distributor is pushing a lot of our clients to make the transition to Wonderware Historian, but doesn't seem to understand that on many sites the standard Citect Historian has been extended with additional functionality to make up for the lack of features and/or performance of the product.

As for the part numbers, I found a list from 2019 that lists these numbers:
VJHNS211011 > CT211011 (150 pt)
VJHNS211012 > CT211012 (500 pt)
...
VJHNS211016 > CT211016 (50000 pt)
VJHNS211045 > CT211045 (100000 pt)
VJHNS211099 > CT211099 (unlimited pt)
