Hey,
How can I make sure some data in the plc does not change values during a plc stop situation or power down situation? Can I make some subroutine that saves some parameters and then makes sure they are the same when the plc powers back up? Problem is I have some integer values that strangely go to zero when the plc is turned off every once in a while. Then if the user does not reload the recipes (which are created also in the plc), the zero causes some problems on the machine. I want to make sure the values never change. Is there some retentive feature?
Thanks
Paul Kemp
