Configuring IEC 60870-5-103 IBB
GUID-605B1ACD-79EB-4C0A-8839-331FD573E41B v1
For changes in status generated by REB500 to be transferred as events to an SCS/SMS, the
corresponding signals must be configured by selecting them in HMI500 Configuration /Binary
module and making the settings in the Event configuration section of the Details dialog box.
To which IBB an event is sent is determined by selecting the appropriate check box IBB 1 or IBB
2 when configuring the signal.
As the 61850 model is implemented as defined by the standard, no custom assignments can
be made for the IBB associated with 61850.

Figure 4:
Configuring signals as events
Diagnostic and system events are always available for transfer whichever protocol is in use
and cannot be configured.
The IEC 60870-5-103 section only appears when the protocol is configured.

Transfer of differential current values
3.4.1
The delta/dead band algorithm
GUID-85BE2C1A-DD67-4564-99E1-CF504CBD06D7 v1
To keep the load on the IBB as low as possible, the bus zone differential currents are checked
cyclically, but only actually transferred via the bus if the value has changed.
