how to change the "Message" parameter of an AE block ..AC800M
The various alarm and event blocks of the AlarmEventLib of AC 800M accept messages up to 70 characters of text.
Using System 800xA NLS, texts can be highly adapted for local language while still having only a short NLS tag ID downloaded to the controller.
However, if your alarm comes from a ready made object type library for which you do not have editor access to, you are left with the text message the developer of the library chose (unless the author of the object type library deliberately chose to put the NLS resource outside the locked/write protected library).
- in CBM, for AE block, define message as variable of type string (follow the default proposal of CBM) with initial value for example "||NLS_Alarm1" (|| is a must)
- in Library structure -> Alarm & Event -> Alarm Collection Definitions -> OPC AE Server for AC800M ->Alarm and Event Translator:
ResourseID = NLS_Alarm1, English (US) = Put your alarm text here
