### Custom Device Drivers

Some LE device drivers (drivers that were downloaded) from the old IONESPMPME system may have become Standard Edition (SE) drivers (i.e. default drivers) in PME 8.2. This results in two entries in the device type list for the same type.

You can see these device type entries in the Management Console: one is an LE type carried over from the earlier version; the other is the SE version that was installed during upgrade.

Manually changing the device type can unlink previously logged data. Therefore, an upgrade to SE should be performed.

The original LE device type might work on the target system but it might not be as fully-featured as the natively-released version.

Note: A possible consequence of upgrading the device type is that any custom diagrams may no longer work correctly.

To upgrade the driver:

1. In Management Console right-click on the device instance to be upgraded, and select Upgrade LE Device.

   A warning message is displayed asking to confirm that it is okay to stop and restart PME Services.

2. Click OK if this is acceptable.

   Clicking OK executes the device upgrade. A message is displayed when the upgrade is finished.

After you close the Upgrade status window, the device type of the instance will change.

Example: TeSysT to TeSys T:

This procedure applies to both CE and LE drivers listed below. The list of drivers that need to be upgraded in PME 8.2 include:

This may not be the complete list for all version upgrade paths.

Note: Any missing LE Drivers should be downloaded from the Schneider Electric Exchange and installed separately. Make sure you download PME 8.2 versions.
