Hi I want to find the UDT instance name from the full tag path(include Atomic member) For example if I have PUMP UDT Class with following member: - run - Motor1/FLT - Motor2/FLT and instance of Pump01 from it and put in Area1 folder. Now if I have Area1/Pump01/Motor1/FLT how can I find the UDT instance name from it which is Area1/Pump01. Note: I don’t any clue how UDT structure when I receive the full tag Path: ‘Area1/Pump01/Motor1/FLT’, so like this example I may have some nested level of folder inside of my UDT. ---

Been covered in > [@Retrieving the UDT tag path from instance tag path](http://forum.inductiveautomation.com/t/retrieving-the-udt-tag-path-from-instance-tag-path/35810/2): > > I’m assuming you are in Ignition v7.9.x, but you might be able to do something like this: tagPath = "[default]Path/To/Tag/Line 2/Filler.typeId" typeId = system.tag.read(tagPath).value print typeId I don’t have 7.9 on-hand to test that out, but I am curious as to the solution. I found that in Ignition 8.0, this seemed to work: tags = system.tag.getConfiguration(tagPath) for tag in tags: tagType = tag['tagType'] if str(tagType) == 'UdtInstance': typeId = str(tag['typeId']) print typeI… ---

Hi I want to get the instance name not typeId. For example I have UDT called PUMP, and I create an instance called P01. So if I have P01/Motor1/FLT how can I get the P01. I can’t use split("/") to extract first part because the instance may be place in folder structure. ---

You can't use your solution here? > [@Grab the UDT instance name and parent folder name](http://forum.inductiveautomation.com/t/grab-the-udt-instance-name-and-parent-folder-name/20521/2): > > I find some solution by using {InstanceName} and {TagName} pre-define parameters. {PathToParentFolder} is return folder path with \ as seperator which i need dot . instead Does anyone know a solution to replace \ with . for {PathToParentFolder}? Thanks. Otherwise, I think you'll have to use a script, as @mmaynard said. ```auto tags = system.tag.getConfiguration(tagPath) for tag in tags: tagType = tag['tagType'] if str(tagType) == 'UdtInstance': imstanceName = str(tag['name']) ``` ---

> [@nminchin](#): > > tags = system.tag.getConfiguration(tagPath) for tag in tags: tagType = tag['tagType'] if str(tagType) == 'UdtInstance': imstanceName = str(tag['name']) For my case because I have always reach Atomic Tag non of the solution work for me. I think of every dirty solution and it works me now. As you see in code below I'm trying to reach some Parameters of my Parent UDT which is called 'HMI'. ```auto UDT = tagPath HMI = '' while True: p = UDT.rfind('/') if p == -1: break UDT = UDT[0:p] if system.tag.exists(UDT+'/Parameters.HMI'): HMI = system.tag.read(UDT+'/Parameters.HMI').value break ``` ---

In the linked script just change up the return to bring back the tag name instead of the type. ```auto # we found the UDT definition tag path, return it #sRet = tagConfig.get(prop) sRet=tagName return sRet ``` ---

Hi Can you explain it a little more or show the code?
