Hello everyone,
following the simple-tag-provider example, I’m trying to develop a module of my own. In my module I need a Dataset variable, which must be editable by the user. I manage to create the tag variable in my TagProvider via code
but it is impossible to edit it in the tag browser: if I double-click on the variable I get a tag editor like that in the following picture
As you can see no Dataset type is allowed for the tag and I get no editor to change the dataset values.
My tag configuration is
and my provider configuration is:
Hallo Kathy, unfortunately I’m currently not at my PC. But I’m sure it is not Dataset. Moreover whenever you open the tag properties, you get the Byte type selected at first, as the Dataset datatype were not recognized.Also the dataset members which are listed below seem to be readonly.
Hallo Kathy, the last entry you asked for is Date. I played a bit more with the SimpleTagProvider and as far as my understanding, with a SimpleTagProvider:
it is not possible to let the user add/remove tag from the tag browser
every time the Ignition service restart, I have no mean to test if the tag provider is there already: I must create the provider again and consequently I loose all the previous tags values.
Am I right?
A tag provider is responsible for everything about its tags, including persistence. Your module must have a means to save any values it wishes to restore.
