I have cause thru scripting to disable then re-enable later the ReadOnly properties of tags. I try with scripting and get this error that makes sense lol. Is there a way or you have to do thru tag browser? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/a/cacfb7651a6887d8004e0729fcd4561739abf1a2.png) ---

writeblocking can be used to change this value `system.tag.writeBlocking(['[Sample_Tags]TagPath/YourTag.ReadOnly'], ['true'])` ~~or `system.tag.writeBlocking(['[Sample_Tags]TagPath/YourTag.ReadOnly'], ['false'])`~~ It can be set to true, but once it's read only, it's read only ---

Have you tried using `system.tag.configure()`? ---

I considered this as well, but based on the behavior of `system.tag.getConfiguration()`, it doesn't seem like it is possible to manipulate the read only property in this way. Am I mistaken about this? ---

Since tags are not read only by default, once the property is set to `True` I would expect it to show up in the configuration pulled with `system.tag.getConfiguration()`. ---

You are correct. I just set up a test, and the script pulled in the read only value: **Code:** ```auto tagConfig = system.tag.getConfiguration('[Sample_Tags]Realistic/Realistic0') for tagDict in tagConfig: for key, value in tagDict.iteritems(): if key == 'readOnly': print key, ' : ', value ``` **Output:** ```auto readOnly : True ``` ---

I haven't been able to get `system.tag.configure` to work for changing read only. **Here is my code:** ```auto tagConfig = system.tag.getConfiguration('[Sample_Tags]Realistic/Realistic0', False) print tagConfig print for index, tagDict in enumerate(tagConfig): for key, value in tagDict.iteritems(): if key == 'readOnly': tagConfig[index]['readOnly'] = False print tagConfig print print system.tag.configure('[Sample_Tags]Realistic/Realistic0', tagConfig, "o") ``` **Here is my output:** ```auto [{u'historyEnabled': True, u'historicalDeadband': 0.1, u'dataType': Float8, u'readOnly': True, u'enabled': True, u'historyProvider': u'Sample_SQLite_Database', u'path': [Sample_Tags]Realistic/Realistic0, u'opcItemPath': u'ns=1;s=[Sample_Device]_Meta:Realistic/Realistic0', u'tagType': AtomicTag, u'name': u'Realistic0', u'opcServer': u'Ignition OPC UA Server', u'valueSource': u'opc'}] [{u'historyEnabled': True, u'historicalDeadband': 0.1, u'dataType': Float8, u'readOnly': False, u'enabled': True, u'historyProvider': u'Sample_SQLite_Database', u'path': [Sample_Tags]Realistic/Realistic0, u'opcItemPath': u'ns=1;s=[Sample_Device]_Meta:Realistic/Realistic0', u'tagType': AtomicTag, u'name': u'Realistic0', u'opcServer': u'Ignition OPC UA Server', u'valueSource': u'opc'}] [Bad_Unsupported("The target path '[Sample_Tags]Realistic/Realistic0' cannot accept children tags.")] ``` ---

when you write the config back you need to go up one layer ```auto print system.tag.configure('[Sample_Tags]Realistic/', tagConfig, "o") ``` ---

> [@wildbilly](#): > > go up one layer Yes. That is the key -- Read only is turned off on my test tag after making this change Edit: putting all together: ```auto tagPath = '[Default]YourTagPath' tag = 'YourTagName' tagConfig = system.tag.getConfiguration(tagPath + '/'+ tag, False) for index, tagDict in enumerate(tagConfig): for key, value in tagDict.iteritems(): if key == 'readOnly': tagConfig[index]['readOnly'] = False system.tag.configure(tagPath, tagConfig, "o") #====================== #Do tag writing here #====================== system.tag.writeBlocking([tagPath + '/'+ tag + '.ReadOnly'], ['true']) ``` ---

Just a note to say that unless you need to ensure the write is successful, you can use `system.tag.writeAsync()` here in place of `system.tag.writeBlocking()`. And also that you should be able to include all of the writes in one call.
