Blocks -1 and -2 are empty blocks used during module startup, when there is no
data to transfer. Negative numbered blocks -4 to -54 are used to initialize the
DNP slave database to specific values during startup, before the port begins to
respond to requests from a remote Master. These negative numbered blocks are
used only if the configuration parameter,
Initialize DNP Database,
is set to
YES
in the configuration file. Otherwise, the DNP database will be initialized with all
values equal to zero.
Blocks 0 to 54 are used to transfer the various kinds of DNP and IED process
data. Block 100 transfers error and status data. Blocks 9901 to 9999 are used for
Special Functions.
