Hello,  

I would like to find out if it is possible to make alarm history a bit less cluttered for easier reading....
So , to start off I am using the alarm history to track major events (machine movements, physical button press etc) as well as actual faults. 
I realize this is not what the alarm history is built for , but this way it serves as kind of a black box, makes it easy to find out during what exact stage of a process has a fault occurred. 
The actual fault also triggers an email to be sent to the maintenance personnel off site, who does not necessarily  have access to the modem unit or the historical values of tags, but only this email. 
Maintenance personnel then reads and deduces why fault could have occurred, what was happening at the time , what buttons the operator pressed etc. 

So for example every time the operator presses the reset button a plc input goes high , which then triggers boolean alarm , and this way it gets recorded in the alam history list , with status being 'Alm', 
What is not so useful is that when the button is released and the input goes low, a second entry will go in the alarm history, with the same tag name and description, except it will have a different status, ie.' End`

So ideally I would like to:

Either not have the second entry in the list ;
Or to have a custom named status for these statuses of the same alarm , ie. ' pressed' and 'released' 

Similarly if there is a better way of creating this black box type solution I would be very interested.


Thank you. 

Regards, 
Peter

Peter,

Indeed the second entry "End" cannot be skipped...
Why don't you use the Historical Logging for tracing the actions of the operator ?

If it is not ok, we could also create a BASIC script to generate custom text reports based on the alarms triggers.

Hi Simon, 

Thanks for your reply. 
All the tags in question are being logged, just was not sure if there is a way to display their value in the email? 
A script could work, do you think I could get something similar to the alarm history , ie. including alarms , events, and time stamps as well?
The plc program is also available to me for adding new tags , 
perhaps I could create tags for all events and alarms including both their states/statuses ie. separate tags for normal and alarm ; pressed and released ; started and stopped etc..

Cheers
