FB_BA_AlmColt12

Functional description

This function block represents a collective alarm for up to 12 individual alarms. Each of these individual alarms bIn01..bIn12 is processed with a FB_BA_Alm within the function block, with a corresponding choice of storing the alarm at inputs bIn01RstReqd..bIn12RstReqd. The states of the 12 individual alarms are output at bQ01 to bQ12.

The output of the group alarm bAlm results from a logical OR link of the individual alarms. Acknowledgement is not required, if no individual alarm was parameterised to require acknowledgement. If alarm storage is enabled via the inputs bIn01RstReqd..bIn12RstReqd, the individual alarm and the group alarm can be reset globally via the input bRst. As already mentioned under FB_BA_Alm, an alarm can only be reset, if its trigger message is no longer active at bIn.

The output bAlmNew is set whenever a new message event occurs at the inputs bIn01..bIn12. It is in any case retentive - irrespective of the parameterisations at bIn01RstReqd..bIn12RstReqd - and is only reset through a rising edge at bRst until the next message event.
