Hello, can someone please see if they have seen this error trying to write to a PLC tag? The script works fine but every once in awhile it locks up, and this is when I noticed this error in the Logs. Thanks. Bad(“Bad\_NotWritable: The access level does not allow writing to the Node.”) this was from ignition logs below: LegacyScripting[system\_util\_tag] 08Dec2021 06:54:07 Error writing tags Error writing to tag ‘[Scanners]Scanner XDO/SORTER\_HANDLE\_LOOKUP/SORTER\_HANDLE\_LOOKUP\_43\_’: Bad(“Bad\_NotWritable: The access level does not allow writing to the Node.”) LegacyScripting[system\_util\_tag] 08Dec2021 06:53:52 Error writing tags Error writing to tag ‘[Scanners]Scanner XDO/SORTER\_HANDLE\_LOOKUP/SORTER\_HANDLE\_LOOKUP\_28\_’: Bad(“Bad\_NotWritable: The access level does not allow writing to the Node.”) ---

Need a bit more information: 1. What version of Ignition is being used 2. What type of PLC? 3. Are you using and external OPC client/server? 4. If you are using Ignition’s OPC-UA what driver are you using to connect. ---

I’ve seen this happen when an online edit is performed and a write is attempted at the same time the logic changes are being accepted. You may want to consider using a try/except block in your script. ---

the tag array SORTER\_HANDLE\_LOOKUP are only written to in one script, when it gets triggered. So i dont think that is happening, Thanks ---

That’s a screen shot of Ignition. The external access control is in the PLC. Please show a screenshot of Studio 5000 showing that tag’s details. ---
