ofer.yishai Posted September 30, 2015 Report Share Posted September 30, 2015 Hello I'm already aware to the fact that transition contacts are not functioning inside UDFB, and there is an example application how to work it out, but what about SET RESET coils? It seems that SET and RESET coils are not latching as should be, if the bit is define as Local tag. Only as Global, Input or Output it works as normal. I tried to walk-around by building a simple holding circuit using simple coil, but this one also refuse to latch in ON state as well. Seems that there is no "memory" for local tags.,, a bit strange as it is very basic logic circuit.. The whole concept, as I understand, with the blessing USFB that one can repeat the same function many times in the project (working less-do more!) But if required to use many global tags (witch are not "duplicate" with the function) as momentary memory (Input and output tag will also be relate to global tags after all), then what is the point? or do I miss something? Any way to latch local bits ? What about numerical local tags, do they keep the value? Thsnks! Ofer Quote Link to comment Share on other sites More sharing options...
