zhangweijing Thank you for your information.If I just want the output action at 15:00 (A35200 to A35207 - Bin code 000001111) and (A35208 to 35215 - Bin code XXXXXXXX) in everyday, how to use the compare instruction. Because the compare insturction is based on the word rather than bit, and I just concerned the lower 8 bit. Could you write the example instruction step for my reference. Thank you
