Writeback error in DeviceBridge

Hi,

I am trying to use Device Bridge to interface with a Datalogic BC9180 barcode reader through Modbus TCP.

I can read holding registers fine through tags, but need to be able to write to certain holding registers as a part of the Datalogic's handshake protocol.

I have tried writing back using the business rule section in both a Dynamic and JSON collector. I have enabled writeback settings in the collector, however I get a 'writeback is disabled' error when trying to run the collector.

In the Device Bridge settings, there is no tab for 'Write Back Settings' - this is strange as the Device Bridge User Manual, and everyone else (e.g. Rajvir https://www.youtube.com/watch?v=9SW-eqey5dc) seems to have these write back settings.

I also do not have the option to select my script type for the business rule (Csharp or Blockly) - everyone else seems to have this option.

I have double checked the following:

  • valid license
  • valid user permissions (logged in as boschrexroth administrator - full priveleges)
  • using latest version of Device Bridge 3.2.4
  • I am able to write to the holding registers using a separate Modbus TCP program (outside of CtrlX works)

I guess I am just confused as to why I cannot see any 'WriteBack settings' in Device Bridge settings.

I have attached all relevant photos to this post.

If it helps, I get an 'app is not installed' warning in the licenses section of the CtrlX web app, however from my research, this seems to just be a bug. I have confirmed in the DeviceBridge Home section that I have a valid license.

I appreciate any help.

Thanks.
