Clearing Data Files N7s

[teal854t 0]

I have data in integer files N7:0, N7:1, N7:2, all the way to N7:99. How can I clear these data at N7:0 to N7:99 at once? Can I use CLR instruction? If so how do I write it? I'm using counter (CTU) to count something. When accu. reaches preset, I will reset the counter and the data from N7:0 to n7:99. Thanks

Look at the FLL or COP instruction triggered by your counter. FLL if you want to set all to zero, COP if you wish to reset them to some preset values. Check manual for processor in question for limits on length and use of file indicator (#). http://literature.rockwellautomation.com/i...rm001_-en-p.pdf may be a good reference.
