Binary and analog input and counter data is transferred from the processor to the
module. The remote DNP master device reads this data. Binary and analog
output data is transferred from the remote DNP master device to the module.
This data is then passed to the processor.
If the module emulates a DNP master device, the database will be as shown in
the following example:
IED MEMORY
BLOCK 100 (DIGITAL
INPUT DATA)
IED BINARY INPUT DATA
BLOCK 120 (DIGITAL
OUTPUT DATA)
IED BINARY OUTPUT
DATA
BLOCK 140 (COUNTER
DATA)
IED COUNTER DATA
BLOCK 160 (ANALOG
INPUT DATA)
IED ANALOG INPUT
DATA
BLOCK 180 (ANALOG
OUTPUT DATA)
IED ANALOG OUTPUT
DATA
Binary and analog input and counter data is read by the DNP master port and
placed in the internal database. This data is transferred to the processor. Binary
and analog output data is received from the processor and placed in the
database. This data is then used to control IED devices on the DNP network by
the master command list.
