How can I acknowledge HMI alarms over the user program?

FAQ #100819

In HMI editor it is possible to acknowledge the alarms over the user programme in 2 different ways.


  1. The easiest way it is using the general aknowledge flag s.hmi.GNRLACK with is available in system symbol, by default when the general acknowledge flag is set to 1 all alarms are acknowledged. Use a dynamisation as follow (no other settings are necessary in HMI Editor)
  2. If it is neccessary to acknowledge each alarm individually then a NAK flag has to be defined for each alarm.
    This NAk flag is set to 1 when the alarm comes, so it has to be reset as follow:
    Attention: Use a different NAk flag for each alarm!
