When upgrading your meter's firmware please download the latest firmware version (.upg file) and the equivalent Meter Template (.dcf file).

You can upgrade meter firmware using ION Setup or ION Enterprise. See the Upgrading ION Device Firmware technical note for complete details.

Firmware version 360 (v360) for the ION7550 adds IEC 61850 server functionality. This includes FTP support and the ability to save waveform data in COMTRADE format.

Important Notes:

• Two versions of V360 firmware are available below: with IEC 61850 implementation (7550V360e) and without IEC 61850 implementation (7550V360s).
• IEC 61850 can only be purchased on 5MB meters, not 10MB meters. If you upgrade a 10MB meter to use IEC 61850 firmware (7550V360e), the meter’s logging memory will be reduced to 5MB. If the meter is subsequently loaded with non-IEC 61850 firmware (7550V360s), the meter’s original logging memory will be restored.
• The non IEC 61850 firmware version (7550V360s) still have new features available, such as COMTRADE waveform recording.
• The ICD files related to the IEC 61850 implementation on ION7550 meters can be found under the Meter ICD Files session below.
