Thank you bobwithdana for your replies, the problem is when I write a rung in RSLgix5000, it contains input side and output side, to avoid any error in the ladder diagram (errors appear when you check your program) you must determine the tag for the input and output, for example:
|-----|I_1 |------------------------------------------(O_1 )-----|
in the previous rung (according to my understand) I will create two tags in RSLogix5000, one for (I_1), and the other is for (O_1). the output (O_1) will do something in RSView32, so I will create another tag in RSView32 named (O_1) (with the same specs for that in RSLogix5000) so I have two identical tags one in RSLogix5000, and the another one in RSView32, in this correct?
thank you
