local time. As no reboot is necessary, the time synchronization starts immediately
after the IRIG-B sync source is selected and the IRIG-B signal source is connected.
ABB has tested the IRIG-B with the following clock masters:
• Tekron TTM01 GPS clock with IRIG-B output
• Meinberg TCG511 controlled by GPS167
• Datum ET6000L
• Arbiter Systems 1088B
IRIG-B time synchronization requires a COM card with an IRIG-B
input.
When using line differential communication between RED615 IEDs, the time
synchronization messages can be received from the other line end IED within the
protection telegrams. The IED begins to synchronize its real-time clock with the
remote end IEDs time if the Line differential time synchronization source is
selected. This does not affect the protection synchronization used in the line
differential protection or the selection of the remote end IEDs time synchronization
method.

3.6.2 Functionality
The IED supports six setting groups. Each setting group contains parameters
categorized as group settings inside application functions. The customer can
change the active setting group at run time.
The active setting group can be changed by a parameter or via binary inputs
depending on the mode selected with the Configuration/Setting Group/SG
operation mode setting.
[1] The line differential protection is available only in RED615.
