Dynamically changing alarm descriptions

[mattsd]

Hello,

in my PLC project (Beckhoff Twincat) I have generic devices 1-10. Within ZenOn (CE version) on a setup page, I assign string for each, ie device1_name = engine room hydraulics, device2_name = engine room cooling etc

Then I read this string for positions on the screen.

My problem is the alarms, I use the limit test for the alarm description, but we dont want an engineer to have to change this description for every project. Can I display a string text from a variable instead of a 'hard' entered alarm description?

It is possible to import commends from twincat. You have to quote the text beside the variable declaration in the IEC format (*asdfjkl*), and then this text is imported in the variable identification. You can execute a VBA macro in the editor where you assign the identification text to the limit text of the limit.

You can use dynamic limit texts, where the alarm text is coming from a string variable in the PLC dynamically.

Please see the embedded help in the editor at the property "limit text" for more information.
