Logging Bools
-
Hi All,
I was just wondering what is the best way to log bools. I have 4 or 5 alarm states that I wish to log when they are active. But I don't wish to log them when they are not. Would the TRND block be best for this or would it need to sample at a high rate creating a large file.
Cheers

Hi Mike,
for this purpose you should use ALB function blocks and the archiving subsystem of REXYGEN.Jaroslav

Hi Jaroslav,
That's perfect thank you, makes sense now. Is there a way I can get the alarm into the HMI. Currently I am using the "simple logger" to show strings for some alarms in the HMI. Can I link the ALB blocks to this somehow?
Cheers
Mike

Hi Mike,
unfortunatelly not. Simple logger is one possible approach. The other is to use RS flip-flop blocks in your task to show/hide alert messages or popup windows in your HMI.Kind regards

Ok, thanks Jaroslav.
I'll use a combination of the ALB and what I currently have to achieve both. This way I'll get both live HMI and logged alarms.
Cheers
Mike
