Communication Protocol Manual
• Compatibility level (COL) = 2
• Eight character ASCII ID string
• Internal code = 4 octets
The eight character ASCII string is of format 615xExx<space>.
• Value 615 and the E character are constant. It stands for 615 series.
• The next four characters identifies the IED type and the variant within the IED
type. For example 615FE02 means REF615 variant FE02 (standard
configuration B).
• The last character (space = ASCII 20H) is not used.

Time synchronization

Time synchronization over IEC 60870-5-103 is supported. This requires that the
IED's global Time Sychronization Source parameter (in Configuration/Time/
Synchronization/Synch source) is set to "IEC 60870-5-103" mode. If some other
time synchronization source is configured for the IED, the IEC 60870-5-103 time
synchronization messages will be rejected.

Disturbance recorder file transfer

The IED includes a functionality that converts the IED's natively captured
disturbance file contents into IEC 60870-5-103 disturbance data. Disturbance files
are also available as standard COMTRADE files through PCM600 or WHMI.
IEC 60870-5-103 disturbance recorder spontaneous Class 1 notification message
(disturbance recorder file directory ASDU 23) can be enabled or disabled via the
setting parameter DREnable n located via LHMI path Configuration/
Communication/IEC 60870-5-103/DREnable n. The default setting is disabled.
Purpose of this notification message is to inform the IEC 60870-5-103 client that
the disturbance file directory has been updated. Usually this means that a new
disturbance recording has been captured and stored by the system. If a disturbance
recorder file transfer is not required from the IED, the notification is also unnecessary.

Disturbance recorder file directory (ASDU 23)

The disturbance recorder files IEC 60870-5-103 identification in the IED is a
sequential 16 bit number starting from 1 at IED reset and is incremented for each
new captured disturbance recorder file.
IEC 60870-5-103 standard defines the disturbance recorder file
identification to be the fault number (FAN), which is the same
number that will be generated by ASDU 2 Class 1 events during the
same fault. The IED could theoretically capture several disturbance
recorder files during the same fault, be triggered by a non-
Vendor-specific implementation
