How Do I Recover a PLC300 H1 Project Created With an Older Version?

Use this procedure to recover an old PLC300 H1 project when the project contains resources created with PLC300 firmware support older than version 1.76.

The recovery requires two WPS versions:

  • WPS 2.00, used to open the old project and export the resource.
  • The current WPS version, used to import the exported backup and update the project.
caution

Create a copy of the original project before starting. Do not perform the recovery procedure on the only available copy of the project.

Requirements​

Before starting, make sure you have:

  • The original project file.
  • WPS 2.00.
  • The current WPS version.
  • The device module required for the PLC300 H1 resource.
  • Permission to install and run both WPS versions, if required by your environment.

Export the Resource From WPS 2.00​

  1. Open the old project in WPS 2.00.
  2. Select the newest firmware version supported by the legacy recovery path. For PLC300 H1, select PLC300 v1.76 when prompted.
  3. Confirm the firmware selection, even if it is the same version currently shown by the project.
  4. Compile the resource before exporting it.
  5. Open File > Export > Configuration.
  6. Follow the wizard and export the configuration as a .bkp file.

Import the Backup Into the Current WPS Version​

  1. Open the current WPS version.
  2. Open File > Import > Configuration.
  3. Select the .bkp file exported from WPS 2.00.
  4. Follow the wizard until the import is complete.

Update the CANopen Configuration​

After importing the backup, open the CANopen configuration file in the resource configuration.

Select the firmware version used during the export procedure, for example PLC300 v1.76 for PLC300 H1. This step is required because the imported configuration may still reference the older PLC firmware version.

Export the Recovered Resource​

After confirming the configuration in the current WPS version:

  1. Compile the resource.
  2. Open File > Export > Configuration.
  3. Export a new .bkp file.
  4. Store the recovered backup separately from the original project and from the intermediate backup exported by WPS 2.00.

Expected Result​

The PLC300 H1 resource is imported into the current WPS version, the CANopen configuration references the correct firmware version, and a new .bkp backup is available for future use.
