HI K!ke,
thank you for the information and your time

But I'm using the TIA portal and there isn't the function BLKMOVE (or I didn't find it...). Indeed I'm rogramming in KOP and the available transfer blocks allow to transfer datas of the same type (not as in the old S7 with the BLKMOVE block).
To resolve this problem iesterday evening I fond a solution making a special FC in SLC language using the function POKE_BLK only available with the SLC.

However this is a posssible solution to my initial problem: can I set a trigger to an allarm message in the section 'Discrete allarms' of the page 'HMI allarms' using directly a bool variable? Someone have idea if it is possible?


Thank you in advance for all the help
Martyn

 I have the same issue trying to configure my alarms also, I can write a Array DB to give me an array of Bools to use for my alarms but I cannot use these as a trigger in the HMI Discrete Alarms. Why would a Bool not be useable in a DISCRETE alarm, surely the use of an INT or Uint makes this an analogue alarm??

Is there a definitive way of making my discrete alarms useable within the HMI or is it the usual Siemens way of making simple tasks really difficult by having to convert, move, re-convert etc?

Thanks

Ian

Here is how I solved the problem with bool-s in array

I have array of 400 bool on location DB870.DBW20.

In HMI tags I made 25 words, selected "absolute acces" and wrote absolute adress: DB870.DBW20, DB870.DBW22, DB870.DBW24,...

In HMI alarms, I inserted for trigger tags those words. With trigger bit you can select specific absolute adress. See pictures
