Problem monitoring the out put

[Dannamo]

Hello
I have problem monitoring my out put wen its true it won't show in the hmi this out put is on
But if I turn it on from the hmi it show the pilot light on coz both the pilot light and the memontery button are the same address B3/0
But if I force the out put to on it won't show in the hmi unless I energize it from hmi

What are forcing on, B3/0 or the output (e.g O:0/0)?

Let me make it more clear to u sir
I did traffic lights ladder logic by three timer
I wanna use the stack light In the Hmi to monitoring my ladder the DN bit of the timer turn the out put ON for the red and orang and green so wen the red turn on I want the stack light in the hmi turn on then orang then green on and on
So what should I put in the plcaddressvalue for the stack light to monitor my output ?

It really depends on how your program is written, but it sounds like maybe something like T4:0/DN
