Cause
It is not very common to upgrade I/O modules. If it must be done, they are upgraded the same as any other LonWorks device without a host processor.
Resolution
- Right click on the target file to store the file locally on the hard drive.
- To be able to download the NXE-file, you need both the NXE and the according XIF-file for the specific device.
- In LonMaker, select Replace or Commission, depending if the device are already in the database or not.
- If the XIF-file already exist in the database, select the correct Device Template.
- In the next dialog, select Load application image. Browse to find the directory for the NXE-file. Change File of type to NXE. Browse to find the directory for the XIF-file. Select Next to decide about source for CP values.
- Select Next, if you do a Replace, you could select the Neuron ID manually, and the old Neuron ID will already be in the dialog.
- Select Finish to download the new NXE-file into the device.
