yes i am a first sem. plc student, have to modify a program in which the count up instruction must not reset if power is lost
we are not using a real plc , my instructor just give us a program and wanted us to modify it. i am new to this so plz bear with me i really want to learn programming
many (most?) of us on this forum are cranky old coots who find those abbreviations highly annoying ...
thanks for the help i am trying to upload the program but it tells me the file is too big if someone knows how to shrink the file i would appreciate the help

from your first post:
I've looked at the program you emailed to me ...
look at the rung that Resets the Counter – and think about what the EXISTING condition calls for ... then come up with a different set of conditions to achieve the DESIRED operation ...
the stuff that you sent was marked "Final Exam" ... what's the story there? ...
