IEC 60870-5-104
The IEC 60870-5-104 communications protocol is supported on Ethernet ports 4 and 5
only. Setting changes become active after rebooting.
FASTPATH:
In 8 Series relay both DNP and IEC104 protocol can work at the same time, but the user
has to consider that there is only one point map. So, the two protocols use the same data
mapping, i.e., same point index and same point source.
FASTPATH:
The 8 Series relay supports up to two IEC104 client connections simultaneously.

By default the Object Information Address for the different data is as follows:
M_SP (Single Points) = 1000
M_ME (Measured value) = 2000
M_IT (Integrated Totals) = 3000
C_SC or C_DC (Single or Double Command) = 4000
P_ME_NB (Parameter of measured value) = 5000
Each Measured value has a Parameter of measured value (P_ME_NB) associated to its
threshold.
The IEC 60870-5-104 Deadbands settings are used to determine when to trigger
spontaneous responses containing M_ME_NB_1 analog data. Each setting represents the
threshold value for each M_ME_NB_1 analog point.
