Hello, I want to ask the discrete alarm in WINCC, that is, how to connect the PLC address and HMI address? Thank you.

example

For example, your alarm signal is

M0.0 alarm 1

M0. 1 Alarm 2

M0.2 alarm 3

M 1.0 alarm 4

Then build a variable address MW0 named "alarm".

Then select "Alarm" as the trigger variable for discrete alarm.

Where bit 0 is alarm 4.

The eighth place is alarm 1.

Number 9 is Alarm 2.

Bit 10 is alarm 3.

Pay attention to letters

16 bit variable can be used as 16 brother alarm signal.

If you have any questions, please leave your email address and I will send it to you through QQ.
