How to configure alarm in Wincc basic V13.

Hello Guys

I am using S7-1214 PLC, and KTP400 basic touch-color-HMI. TIA V13, step7 and wincc basic. I have completed programming, and HMI design, but do not know how to configure alarm. I had a training last week, but lost all the notes that i have taken. So What i know is, i should create a separate FB for alarm function in the PLC program block, and the output type is word, and each bit of the word corresponds to a particular alarm. I do not know how to change the output, from bool to word. And how to set it up in HMI Alarms. I downloaded this pdf from siemens, configuration of messages and alarms in WINCC, but it was not helpful. So can some of you help me, a good technical note can help... 

Thanks... 

Hello JAC2016,

there is two part of this:

1) Generate a word as alarm trigger tag in the plc from a bunch of booelan tags.

2) Add alarms to the trigger tag in HMI.

So... about 1):

You need to set/reset a bit in the word tag if a correlating bool is set/reset.

How this Looks depends on your programming language. One very basic option would be to add something like:

IF #bool1 THEN
#triggerTag.%X1 :=1;
END_IF;

 You can do this for each bool.

Alternatively you use a loop of some kind, for example:

You Need an array of bool 'boolarray(0..lastBool)'

FOR #index :=0 TO lastBool DO

IF #boolarray[#index] THEN

triggerTag := DECO (IN: #index);

END_IF;

END_FOR;

 The function "DECO" sets the bit on the position of #index to 1.

Don't forget to reset your triggerTag word to 0 if the Alarm is going/acknowledged.

Got it, I configured the alarm... I will try it as soon as the HMI comes ...

Hello JAC2016

There is, as you can see, lot's of ways solving this issue. Thy to see this FAQ, basicly solving the same problem, but using the AT overlay.
