Custom tool for tags creation

Ignition
1

Hi all
My customer would like to create Tags without using Ignition Designer. Is there any endpoint to connect to for Tags creation from outside? Or a tool like gcu, that could get a CSV file in and create gateway Tags accordingly?

Thanks in Advance, regards

Yes, they can do this from vision (definitely, have done it) client, probably perspective (with a bit more work due to file access restrictions).

Open the CSV file. Parse it. Script with Jython to create the new tags.

# This example will add a new OPC Tag. It can be further expanded to modify more
# properties on the Tag. Additionally, this example can be used to edit an existing Tag
# by setting the baseTagPath to a Tag that already exists, and by modifying the collision policy.
 
# The provider and folder the Tag will be placed at. 
baseTagPath = "[default]MyFolder"
 
# Properties that will be configured on that Tag.
tagName = "myNewTag"
opcItemPath = "ns=1;s=[Simulator]_Meta:Sine/Sine0"
opcServer = "Ignition OPC-UA Server"
valueSource = "opc"
sampleMode = "TagGroup"
tagGroup = "Default"
 
# Configure the tag.
tag = {
            "name": tagName,           
            "opcItemPath" : opcItemPath,
            "opcServer": opcServer,
            "valueSource": valueSource,
            "sampleMode" : sampleMode,
            "tagGroup" : tagGroup
        }
 
# Set the collision policy to Abort. Thus, if a Tag already exists at the base path,
# we will not override the Tag. If you are overwriting an existing Tag, then set this to "o".
collisionPolicy = "a"
 
# Create the Tag.
system.tag.configure(baseTagPath, [tag], collisionPolicy)

No.

Everything is supposed to be an API when 8.3 comes out, though.

In addition to a dedicated Vision or Perspective solution, you could also use WebDev to create an API.

Hi @Matrix_Engineering, thanks for your suggestion: I know I could, but I was wandering if there were anything ready to go.

Hi @pturmel , that sounds very good! Will that mean that through RESTful webservices calls it will be possible to configure some or any gateway/project parameters?

Thanks, regards

That's what Carl said at ICC this year.
