system.device.addDevice() Only Works Once

Hi all,

I am experiencing a strange behaviour when trying to use the system.device.addDevice scripting function.

I have a component script on a button that uses the system.device.addDevice function to add devices to the gateway with device parameters defined by the user. If the a device with the same name already exists, the script will first delete the device then re-create it.

The script works perfectly fine on my development VM that’s running the same version of the Ignition as the actual site version.
7.9.8 (b2018060714)

However when I run it on the actual server on site, the script will successfully once, the next time the script runs I get the message attached below. Then if I close the client down and launch again, the script will run successfully for once again. It’s complaining about driver type is not specified but it’s definitely is specified.

Both my development VM and the actual site server are using the same Java version Version 8 Update 66 (build 1.8.0_66-b18).

Can’t quite figure out where the problem is…if anyone had any insights or suggestions it will be much appreciated.

Thanks!

Ignition v7.9.8 (b2018060714)
Java: Oracle Corporation 1.8.0_66

This looks like the issue. Are you selecting a driver to use in your script?

Hi Jonathan,

Thanks for your reply.

Yes, the driver is specified. So the script works fine for the once then after that it stops working until I restart the client. The same script works fine all the time with no issues on my development VM even though the version of the Ignition and Java are the same…the only difference is the OS.

Problem solved. Silly programming error…
