Studio 5000 Bit Change For Alarm

4 posts in this topic

Hello All. I am new to automation so please excuse my explanation. I am working on a request where I need to reset 2 alarm bits (AlarmError1_Alarm and AlarmError2_Alarm). When they are active (1), I need to create logic using Studio 5000 to put them back to 0 using the AlarmReset_PB_HMI. I have added two pics to better explain. I am not sure if this can be done in FB or ladder.

First - I have nothing against FB programming. When I need it I use it.

For clarity - in my line of work an alarm is used to tell the operator that something that he can affect is impending, and I don't latch those. A shutdown is latched and and must be reset. All of that is done in ladder logic. Use a one shot (positive edge trigger) between your reset button and unlatch otherwise the button can "fault" or, more commonly seen, the operator can hold the button in and bypass the alarm or shutdown. Or a jumper clip can be installed. Or someone could sharpen a stick and jam it into the button. I've seen all three happen.
