I trying to adress to data file x and word x with my full access page on my Panel View 600. It's work well, but when a entry a incorrect word, for example, a integer n7:100 and it doesn't exist the plc goes in fault. I try to unlacht the bit S:1/16 but i can't, the plc is in fault.... What can i do if a want to access in my data files (any integer, timers, float point) and to prevent a fatal error from my plc.. thank you
