Hi,

I have a script that tries to get the configuration from a dataset memory tag with system.tag.getConfiguration(), then modify the configuration and then write the changes back to the tag with system.tag.configure().

However I get an [Error\_Configuration] when trying to write the modified configuration back to the dataset tag.  
I even get an [Error\_Configuration] when trying to write an unmodified configuration back to the tag?

Is there some limitation with system.tag.getConfiguration()/system.tag.configure() when it comes to dataset tags?

Thanks

I dont know of any limitations.

Have you tried running it in the script console? might help you debug it. Show us the full error message and code?

I am running it in the script console. You can easily make the same test.

```auto
c1 = system.tag.getConfiguration('[Provider]Folder/Tag')
print system.tag.configure('[Provider]Folder/',c1,'o')

```

The output console just says ‘[Error\_Configuration]’?

If I do the same test with a tag that isn’t a dataset tag the operation succeeds with ‘[Good]’ in the output console.

Hm that works for me tho, are you sure the path’s to the tags are correct?

Ah it seems if there is data in the dataset i get the error too let me check  
yeah so running

```auto
c1 = system.tag.getConfiguration('[default]Project/New Folder/Dataset', True)
del c1[0]['value']
print system.tag.configure('[default]Project/New Folder/',c1,'o')

```

works but then you lose the dataset so you will have to add it back after i guess… weird

```auto
c1 = system.tag.getConfiguration('[default]Project/New Folder/Dataset', True)
print (c1[0]['value'])
value = c1[0]['value']
del c1[0]['value']
print system.tag.configure('[default]Project/New Folder/',c1,'o')
system.tag.write('[default]Project/New Folder/Dataset',value)

```

I’m pretty sure we bumped into the same thing in Ignition 8.1.7. I whittled it down to a simple test case.

If I have a dataset stored in a tag at `[default]sandbox/testds`, this code will work:

```python
src_path = '[default]sandbox/testds'
dst_path = '[default]sandbox'
dst_name = 'goodds'
src_config = system.tag.getConfiguration(src_path, False)[0]
dst_config = dict()
dst_config['valueSource'] = src_config['valueSource']
dst_config['dataType'] = src_config['dataType']
dst_config['name'] = dst_name
dst_config['value'] = src_config['value']
dst_config['tagType'] = src_config['tagType']
system.tag.configure(dst_path, [dst_config], 'a')

```

But this code will fail:

```python
src_path = '[default]sandbox/testds'
dst_path = '[default]sandbox'
dst_name = 'badds'
src_config = system.tag.getConfiguration(src_path, False)[0]
for x in src_config:
  if x not in ['valueSource', 'dataType', 'name', 'value', 'tagType']:
    src_config.pop(x)
src_config['name'] = dst_name
system.tag.configure(dst_path, [src_config], 'a')

```

The error is the same as others have shown:

```

I’m confused as to what is different between the bad sample versus the good sample.

EDIT: And this one will work:

```python
src_path = '[default]sandbox/testds'
dst_path = '[default]sandbox'
dst_name = 'newds'
src_config = system.tag.getConfiguration(src_path, False)[0]
dst_config = dict(src_config)
for x in dst_config:
  if x not in ['valueSource', 'dataType', 'name', 'value', 'tagType']:
    dst_config.pop(x)
dst_config['name'] = dst_name
system.tag.configure(dst_path, [dst_config], 'a')

```

Looks like the magic combination is to make a new `dict` to hold the config and to drop the `path` entry from the dict when copying it, although I prefer to drop all the fields I don’t expect/need.

But why?
