Lookup Table

I am returning to PLC programming after a 4 year absence. I have primarily used the GE 90/30. I am looking for clues on the most efficient method to pull data out of a matrix. For example, both the rows and columns are labeled in percent from 0 - 100 in 10% increments. The rows and columns are the pointer to the piece of data in this 11 x 11 matrix. If info on this is in an old post, please pass that along if easier. Thanks very much

Are you still using a 90-30? Are you familiar with the Array_Move and Array_Search functions? How are the rows and columns in the matrix mapped to register addresses in the PLC?

Yes, i am using a 90/30, and i can map the data however i want. If those are the key instructions to use i'll read up on them and figure it out. i hadn't used them before. Thanks v much
