Hi,
I receive via mqtt a large string with the value of my tags and I'm separating it by ";" so I made a script to separate the values of this string.
tag_path = ("[MQTT Engine]texto")
tag_value = system.tag.read(tag_path).value.split("; ")
print tag_value [2]
Up to this point, we're OK, it's working properly and I can see it from the console output. My question is how can I take this value that comes out of my script and assign it to a Tag?
system.tag.writeBlocking | Ignition User Manual
# Create a list with the tag paths to be updated.
paths = ["[default]Folder/Tag_A","[default]Folder/Tag_B"]
# Create a list with the update values, one value for each path.
values = [1,2]
# Execute the write operation.
system.tag.writeBlocking(paths, values)
Unless you want to do it Asynchronously:
It's tempting to put it in a script within the tag, but do it in a Gateway Tag Change script, instead.
tag_value = event.currentValue.value.split('; ')
system.tag.writeAsync(['[default]path/to/my/tag'], [tag_value[2]])
