FBs for Alarms

PLCnext Engineer
1

Hi,

As mentioned in the PLCnext Technology User Manual, there are Alarm function blocks mentioned for the PLCNext Engineer, unfortunately I was unable to find those in the Programming components… Could you tell me whether I am missing something out, or is it a not-yet-implemented feature inside the PLCNext Engineer? In my use-case, I want to use the alarms signaled by the C++ libraries (managed to get it to work with the C++ code) to communicate a critical state of the system to the operator via the eHMI interface. Do you think, that there could be a way to facilitate this if the Alarm block are really missing out from the PLCNext’s IEC61131, if possible I would prefer to avoid using additional GDS ports.

Kind regards,
Michael Czorniej

Hello Michael Czorniej, which Version of PLCnext Engineer are you using? You should find alarming funktionblocks at

Programming → PLCnext Controller → Alarm
Are these the Functionblocks you are looking for?

“ALM_ALARM” ect.

Note:
You need to include the Library PLCnext Controller

kind regards,
Oliver

Hi Oliver, I’m using v2019.9. Indeed I am looking for the block mentioned by you.

In my PLCNext Engineer I am unable to locate the specified folder in the programming tab, see the attached picture. I have tried to search for the blocks by name, but without any luck as well.

Regards,
Michael

Oh, did see the note. After importing the library, I can find the blocks now.

Thanks.
