HSC resets DW counter after power-cut

[Nassos.NET]

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,

Nassos

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.

@Mirko, are you having a problem we can help you with? This is your second post that just quotes others but has no content. Should I delete those?
