I have multiple ProSoft cards in the same rack and using Add-On Instructions (AOI). Can I edit the ReadData and WriteData array size for each specific card?

Yes.The ReadData and WriteData array sizes are found and edited in the 'MCMDATA' UDT.By default, when multiple AOI's are imported according to the user manual, they utilize the same UDT.  Therefore all cards using the AOI will have the same lengths.If each card needs different sizes of ReadData and WriteData arrays, please follow the attached Tech Note:
