Hi. I'm a complete novice but trying teach myself ladder. my previous experience is with function on the la crouzet software. The problem I'm having is with my hsc, in that I need to take rpm, which I can achieve using a 5 sec timer, which also resets my HSC count. This is a problem as I need a continues count as well. I can also achieve this but not both together. as soon as I use a store function, I cant manipulate the original count. Is there a way to retain the HSC count and also manipulate the count in another operand to achieve a re-settable rpm reading? I'm using an inductive sensor on the shaft with a vision SM70-JR20. TIA.
