I was hoping to use FieldRead to do this but I'm having difficulty moving the input words into an array. Does anyone know how I can do this? Thanks Best Regards Rich

I have attached here some simple example in S7 V5.5 Hope helps Attachment ArrayExample.zip (306 Downloads)

Thanks for the reply, i know i can use the move for each individual word. Is this the only way? I was hoping to move all 10 word in 1 go. In my actual application its 43 words to move into the array so I was hoping for some kind of SCL loop I could write?
