Masking out values

Hello all, 

I am trying to mask out some values out of a bar code from cognex data scanner. Here is an example of what I am trying to achieve

Data from Cognex: 2275019xf1-8877R215BA1234567

i just need 2275019XF1-8877R215B 

I know i can program the bar code scanner to not to read but that would cause a lot of downtime. I wanna to know how to mask such a big number. Any help would be appreciated. I would be using RSlogix5000

Thanks
