  1. Hello Omron programmers, have a nice day to you all. I just need your help in this, i hope you have explanation.  I added a few sequence to the machine with compare instruction D2255 and D2259 as memory data. I really wonder what’s going on. D2255 a decimal value of 9, when it transferred to compared instruction it’s 9, but when D2255 become 10 or above, when it transferred to compared instruction it will become 16 or above, there is an additional of 6 to the decimal value when it more than 9. I attached the photos of it for more details. Can somebody please help me? Thank you.
