Logix 500 into Logix 5000 maths conversion

Hi all, I am trying to copy paste a routine from rs logix500 into rs logix5000, I get an error on rung where they are searching for scada values F22[C5.ACC], I have tried replacing "[]" with an underscore sign but it still not taking my expression...Any idea please on what should a replace these [] with?

Thanks

Welcome to the forum.

In this case F22, a file of reals in RSL500, is being accessed by indexing into the file with the accumulator contents of C5. So in RSL5000, F22 would have to be defined as an array of reals named F22.
