If Alarm buffer will completely fill , What will happen? FIFO or any other action...?ea
Am using CP676 HMI. In alarm buffer , They mention max size of buffer is 2048.
That 2048 means 2048 entries or 2048 KB ?
once that 2048 filled what will happen,FIFO or any other action?
Can we show the audit trail in HMI?
that means i want to show the details of motor on time ,off time,trip time.
Local storage of events will affect the HMI ?
In my version alarm buffer is defined by default to 1000 (assume that is 1000 kB which is a big number of alarms), and you can't change it. So if you need 2048, you have to create a new alarm buffer *custom type)
But I think that a total sum of all buffers is 2048, I don't know. The help is limited.
From my experience, the alarm buffer is FIFO, right. I tried with other panels, it is working like that.
Audit trail I think you can only export to CSV file (DumpEventArchive), and not possible to view on HMI (that is described in the help). You can try in simulator and save the file to hard disk of your PC.
For time meters I create own counters in the PLC, and visualize it's content on the panel.
