roberto.zeni@sistemizero.i Posted March 18, 2021 Report Share Posted March 18, 2021 Hi, we have a system with a simply encoder that measures a distance. We set a weight of each pulse and so we simply multiply this weight for the counter value (On Board IO.HSC-0 Counter value). The system work well but we note that when the PLC is switched off and after on the counter value restart to zero (and so our logic fails...). We can also store the counter value in a retentive global tag but at PLC startup we cant store this value in the HSC counter... What's the best way to handle it?

Gabriel Franco Posted March 18, 2021 Report Share Posted March 18, 2021 You can use inverted contact of "General.Ladder Initial Cycle" as a condition to store from your HSC to a global tag. Quote Link to comment Share on other sites More sharing options...
