Hi everybody!
I have a KTP400 Panel. I want to create a discrete alarm, example: when "START" button is pushed, alarm text displays "Machine Starts". But I can't do that. Hope getting your helps!
Thanks everybody!

Thanks Ste39!
I read Wincc_TIA_alarm document. In Configuration of discrete alarms section, types of data for trigger tag are int, word, uint but type of my tag for alarm is bool. I don't understand that. Can you explain for me!

Hello MrBin,
You can select a variable of type WORD and specify the trigger BIT of the WORD.
or
You can convert the discrete alarms at PLC to a WORD or UINT and transfer to a HMI.
If you have more than 16 alarms you have to create a new WORD or UINT and trasfer to HMI.
maybe this can help you:
How can you group separate signals (variables of the "Bool" data type) to one variable of the "Word" type and again extract them from that "Word" variable (Bool - Word data type conversion)?
