Tag Name maximum length for ICU transfer error

Hi, I've had an ICU transfer working from SQL to PI for ages but after adding some new tags I am getting them rejected in the transfer, as somewhere along the way the tag name is being truncated to 30 characters and my new tag names are longer than that, and of course they now don't match what's in Archive. The original ones must have all been <30 which is why they still work. Looking through the UniInt doco (page 17) we meet the criteria on versioning to allow a max length of 255 characters. SDK shows me the tags have been created and where the tag name is <30 characters in this new tag set the current value actually shows the data. This is what has led me to the length of the tag name being too long. The maximum length is 49 from my new set. Does anyone have any suggestions as to how to fix this? PI SDK is enabled in the ICU. UniInt ver 4.5.5.22, everything else 3.4.400.1162

Many thanks,

Ray
