Hallo.

I have made a screen item data (button) for messages with name "ΜΗΝΥΜΑΤΑ" to a KTP400 basic.

I need that when the 'HMI alarms word' tag ( which is connected to the correspond plc alarm word tag) has the value 0, the button will become green.

When the value is becoming 1-3, the buton will become yellow and when the value of 'HMI alarms word' tag will become4-6, the button will become red.

However the button is always green.

As you can see in screenshot, i have chosen 'range' type.

If i choose 'multiple bits' type, the appearance of the button will depends on of the situation (0 or 1) of any bit of the word 'HMI alarms word' tag?

For example:

bit0 high then button green

bit1,2,3 high then button yellow

bit4,5,6 high then button red

Thanks in advance

I use Tia Portal V13 SP1 professional.

In screenshot you can see the plc 'Alarms tag table'.

I use MW because the value of Alarm Word contains some other bool alarms as:

MW bit0 (M40.0) Oil Level alarm

MW bit1 (M40.1) Glogged filter alarm

MW bit2 (M40.2) Motor alarm etc.

So the value of MW is determined from separate bit 0,1,2 alarms.

I have no way to implement this in a data block.

Besides, i must say that i'm a little confused about how i can use data blocks for that reason i use plc tags M.

 If you have PLC word tag bit 1, 2 or 3 ON, the value in the word is not between 1-3. You should monitor the value in the PLC to see what numeral values comes, when the bits are active.

You said that you use MW40, that means that M41.0 is bit0 of the word.
