I am working with an Allen Bradley PanelView Plus 700 HMI screen (Part No. 2711P-T7C4D8) and seem to be having problems with my alarms. The screen works fine all day but each time I arrive on site in the morning no active alarms are being displayed. Everything else on the screen seems to be working fine. This I assume is due to the alarm buffer having become full. After a quick reboot all is well again. I have added a button to clear the alarm history which it does but it doesn't restore my active alarms.
In my project I have one page which displays active alarms and one page which displays the alarm history. In the alarm settings I have defined my display Active Alarms for alarm messages and set it to display both Active and acknowledged and Active and unacknowledged alarms. On my alarm history page I have set it to display both active and inactive alarms which are acknowledged and unacknowledged. I have tried reducing the history from the default value of 128 to 96 and now down to 64 which has made no difference. I have also tried reducing the alarm update time from the default 1 second to 2 seconds but again this has made no difference.
I took the screen apart yesterday and it doesn't look like there is any way to increase memory size (Just an SD card slot) and there are no sliders in the screen control panel to adjust program and RAM usage.
Any ideas?
Regards,
Barry
