I could do with a hand please - so I have a massive list of alarms with the description stating what they are in some local tags.
So, like
Loc_Alarm[3].1 -> Value: 1 -> Description: GenAl_121_F1-3_OvertravelError
I want to put these descriptions into a text array so, for example the above would transalate to:
TextAlarms[756] -> Value: GenAl_121_F1-3_OvertravelError -> Description: Null
Now I can do this on a HMI by referencing Loc_Alarm[3].1.@description and I hoped I could do it in the PLC by using a MSG with the remote element set by a string to Loc_Alarm[3].1.@description but I get "Invalid value in object specific data parameter of service request"
I want to do this in several PLCs, so I'd like to avoid awkward solutions like writing the .@description back from the HMI or anything that involves a download or too much manual intervention if possible.
Has anyone had success or can think of method to try to get this information? -> All the PLCs do have access to transaction manager and an SQL database if this offers a route to read the descriptions.
Regards
Ed
