Hello

is possible to use logo for discrete hmi alarm?..

If yes then how.

thanks for all answers...

Try using a "network output".

From the example you will have VW0 as the WORD that is used for triggering bit alarms. Take care that V1.0 is the 1st bit, V1.7 the 8th bit, V0.0 is the 9th bit and V0.7 the 16th bit.

Network output is data type BOOL

Yes.. and there are 16 BOOLEAN bits in a WORD.
The bits (ex. V1.0) is always linked to a WORD (ex. VW0) for the LOGO.

Another example.. (sorry - I do not know if you know Siemens systems)
VW12 is constructed by BYTES VB12 and VB13, which in turn each BYTE with 8 bits. VB12 from V12.0 to V12.7 and VB13 from V13.0 to V13.7.

Careful! - V13.0 is the least significant bit and V12.7 the most significant in the WORD VW12. This is contrary to other systems. Also note Siemens works in 8 bit groups, not 16.

Many thanks.
