I want to in a mp277 panel touch, can disable alarms. I think that maybe it is posible to into in the panel in a field the number of alarm to disable, and execute a script to disable it. ¿Is there any option to disable an alarm directly from script? Thanks in advance. Regards Darío Fernández

Hi Dario, why would you want to disable the alarm? Isn't it just better to acknowledge it via the HMI panel but let the alarm be active. I'm thinking just for security, you can't really say the alarm is not there when it is, that's kinf of an unsafe situation. Take a look at acknowledging alarms, maybe it's of more use for you. If it isn't you can always create some LADR or FBD logic to set the bit in the alarm word to HMI to zero. This way the alarm will dissapear on screen. I highlighted alarm word to HMI because I think you should still send this alarm to DCS and not fully ignore it. The alarm should still be present in your program. I hope this helped and offcourse correct me if I'm wrong. Kind regards, Jens

Thanks in advance. Regards Darío Fernández may be you can use a button on the HMI that will set a boolean tag and use that bit on your PLC program to reset and stop sending alarms to HMI, another button for reset it

Thanks for your suggestions, if I can't do it by this way, I will try as you recommend. Regards Darío Fernández

Ste39 Posts: 4620 Rating: (710)	Hello Dario, As our friend says Jens_app leave them there and do not recall variables dedicated to them. I in my panels in discrete alarms write all the error messages and I do a DB or bit memory area (if there are few reports) and do not recall if these areas do not need it and I never had any problem.

I need to disable alams in HMI sometimes, for example when a part of the machine is going to be changed and an alarm of it will be a few days on. I want to be able to disable this alarms, but I want to do it on HMI (to only see there "true" alarms) and not in PLC, to know there that the alarm is on. I didn't find any option to disable alarms directly, so I did a script to do that. I did a easy script where I use a bitmask to select de alarms to disable it, so for example if I want to disable alarm on bit 0 I do: PLC_Alarms = 1111111111111111 (Suppose a word of alarms all of then actives in PLC) Bitmask = 0111111111111111 (Bit 0 of bitmask to 0) HMI Alarms = PLC_Alarms And Bitmask So in this case HMI_Alarms will be like Bitmask "0111111111111111" and alarm 0 of PLC isn't show on alarmview. To disable alarms I do: Putting the number of the alarm on a I/O field, and select to disable or enable this alarm with a button. Then I show the disabled alarms in a different Alarmview to didn't forget it. If anyone want I can share an example to disable alarms on this way, so no hesitate to ask. Regards Darío Fernández
