Im using system.tag.getConfiguration(tag)[0][‘opcItemPath’] We are using a lot of UDT instances with UDT parameter bindings. When I get the configuration for the opc item path, it returns these bindings in this format: {bindType=parameter, binding={myParam}.“the Rest of the path defined in UDT definition”} when I try to pull out the value of the binding by using something like print config[‘opcItemPath’][‘binding’], I am met with this error: Traceback (most recent call last): File “”, line 11, in TypeError: ‘com.inductiveautomation.ignition.common.config.BoundValue’ object is unsubscriptable So, i’m resorting to using string splits to access the bound value which feels like such a workaround. Isn’t there a better way? ---

Still finding the object to be unsubscriptable when I try and get to the value of some binding of a udt instance. ```auto cfg = system.tag.getConfiguration(tag)[0] print cfg['parameters']['Comm_name'] print cfg['parameters']['Comm_name']['value'] ``` Printed results are: ```auto >>> {datatype=String, value=ACOSTA1_RTU} Traceback (most recent call last): File "", line 8, in TypeError: 'com.inductiveautomation.ignition.common.tags.config.properties.ParameterValue' object is unsubscriptable >>> ``` ---

I’ve got exactly the same problem today. Did you ever find a better solution than parsing the string? ---

Unfortunately it’s been crickets. Kind of a hassle to get a simple tag config parameter. Hopefully someone chimes in here and shows us the way! ---

> [@tmahaffey](#): > > print config[‘opcItemPath’] `print config['opcItemPath'].getBinding()` or `print config['opcItemPath'].binding` should work - the latter is Jython syntactic sugar for the former. ---

I was recently trying to search for answer to this same question. I reached out to support and they gave me some info from the SDK documentation which provides the answer. ```auto tags = system.tag.getConfiguration("[default]_types_/", True) #print tags for tag in tags: tagConfigs = tag #print tagConfigs for key,value in tagConfigs.iteritems(): #This is all of the tags in the _types_ folder #More specifically, this is a list of configurations for each of the tags in this folder if key == 'tags': tagConfigList = value #print type(tagConfigList) #Becuase it's a list we must loop for each item in the list for tag in tagConfigList: tagConfig = tag #Now, we get an actual dictionary of configurations for each tag print "UDT Configs:" for key,value in tagConfig.iteritems(): #These are all the properties (or keys) for the UDT print "KEY:",key,"| VALUE:",value #Parameters seems to have another dictionary for its value if key == 'parameters': parameterValueDict = value print "--------------------------------------------" print "Parameter Value Dictionary = ",parameterValueDict #This is a dictionary type so I will get the key,value pair again for key,value in parameterValueDict.iteritems(): print key,value #This seems to have another dictionary as its value print type(value) #But it's not a dict type #It's a com.inductiveautomation.ignition.common.tags.config.properties.ParameterValue type! #So we cannot use iteritems again parameterValue = value #But we can use this method from the java docs to easily get the type of the parameter print "This Parameter is a:", parameterValue.getDatatype() print "This Parameter's value is: ", parameterValue.getValue() ``` Also if value is of the type \ e.g. value={bindType=parameter, binding={InstanceName}} then you can use ```auto value.getValue().getBinding() value.getValue().getBindType() ``` > **Summary** > > This text will be hidden
