Hi there!
I'm using mitsubishi plc for some project controling. I try to use high speed counter C251 to reading an encoder. I use two function move(MOV) and HSCS(interupt set bit) relate to value of C251 but It can't work even the counter was got value. I tried this code with Fx2N-32MR and it work well.
What happen with my FX1S plc:
