Hello,  
I am using Ignition 8.1.22 trying to write a value into the properties of a UDT Alarms Properties using the system.tag.writeBlocked function but when trying to access the Alarms section provides Bad\_NotFound error.

path = ["[default]_types_/MHE/VDL/FSC/ACZ22/OPC/RsDetails/IO error.UID"]

value =[10]

system.tag.writeBlocking(path,value)

I was able to write into the parameters up to the RsDetails but not into the Alarms. Any help is greatly appreciated
