Hi There,

I am wondering if it possible to configure an alarm message string dynamically.
What I mean by this is in the alarm configuration, I want to have the message display a string from a text list dynamically at runtime.
Does anyone know how to achieve this?

Cheers,

Louis.

Hi Louis!

I don't know, if there is a way directly in the alarmmanager. I would solve it with a short piece of program, like this:

VAR
   asMessageText:      ARRAY[0..8]OF STRING := ['No Message', 'Message 1', 'Message 2',
                                     'Message 3', 'Message 4', 'Message 5',
                                     'Message 6', 'Message 7', 'Message 8'];
   sAlarmMessage:      STRING;
END_VAR
IF byPowerPackEStopDiag <> 0 THEN
   sAlarmMessage:= asMessageText[byPowerPackEStopDiag];
END_IF

In the Alarmconfiguration you can use <latch1> as a placeholder for the text:</latch1>

Maybe this helps?

Good luck

Hi,

Thanks for the reply,
Yes I ended up doing this (something very similar), In theory it should work fine as the documentation says you can define a STRING as a latch variable. I tried it in the simulation but it would not display the STRING value. I also tried a unicode WSTRING with no success. I will try this method once I have some hardware in front of me to try it on.

Thanks for your help.

Dear poster,

I tried the of the dynamic string alarm texts via <latch1> and it works wonderful in v3.5.11.50 based hardware.</latch1>

Thanks for sharing!

Hi Hermsen,

Much appreciated!
