2.2 Multipoint FlexLogic Operand States
2.2.1 Bus Differential Operand States
Each zone has 6 different states shown in
Table 2-32
. Each one of them corresponds to a different
bit in the data item.
Table 2-32 Bus Differential status bit field
The zone states for all 4 relay instances span across 2 consecutive modbus registers as shown in
Table 2-6
. See
Bus Differential Operand States (2 items) on page 136
for memory locations.
