Hello to everyone,

I have a SM35-J-T20 and a set two HSC as Counters


and i notice that when there is a power-cut the DW values will reset to Zero.

is there a way to avoid this reset?

Thanks in advance,

At the end of program (at the end of every scan) copy those registers into some other free DWs. Then at startup copy them back, via SB2 contact.

I think there should be a complete example of this method somewhere in this forum, I've seen this topic before.
