A small number of units ("4 wire M12" versions ending with -3, -4 or -5) were found to have been built with duplicate MAC addresses.
If the MAC address is 00:1d:8d:30:00:01 - it should be changed. You can find the MAC address on the device label or in Device Information using DTMD v6.
If you are using multiple sensors in a single installation and you can communicate with only 1 sensor, you will likely see the affect that you can only see one sensor. If you only have one sensor you are not likely to be affected.
Special Note: Duplicate MAC addresses are not allowed in any network.
The zip file contains file only with affected serial numbers.
Please use the following procedure or create a ticket so that we can provide guidance or perform the change via remote connection:
1. Download and unzip the attached file mddMacUpdates.zip
2. Extract the content of the zip folder into another folder - right-click and choose Extract All
3. Download and install Datatemp Multidrop v6.1.99, please create a ticket if you need a download link New Ticket
4. Connect to the sensor via the known or default IP address
5. Verify the serial number in the Device Information list
Special Note: It will be necessary to modify your PLC configuration after the MAC address change
6. Via the Restore Device Configuration button
7. Navigate to the unzipped archive and choose the file with the serial number that matches the connected sensor. Click Open
8. Application log will confirm success
8. Refresh the Device Information list to confirm that the MAC address has changed
