# initialize your data store
# ----------------------------------------------------------------------- #
# The datastores only respond to the addresses that they are initialized to
# Therefore, if you initialize a DataBlock to addresses of 0x00 to 0xFF, a
# request to 0x100 will respond with an invalid address exception. This is
# because many devs exhibit this kind of behavior (but not all)::
#
# block = ModbusSequentialDataBlock(0x00, [0]*0xff)
#
# Continuing, you can choose to use a sequential or a sparse DataBlock in
# your data context. The difference is that the sequential has no gaps in
# the data while the sparse can. Once again, there are devs that exhibit
# both forms of behavior::
#
# block = ModbusSparseDataBlock({0x00: 0, 0x05: 1})
# block = ModbusSequentialDataBlock(0x00, [0]*5)
#
# Alternately, you can use the factory methods to initialize the DataBlocks
# or simply do not pass them to have them initialized to 0x00 on the full
# address range::
#
# store = ModbusSlaveContext(di = ModbusSequentialDataBlock.create())
# store = ModbusSlaveContext()
#
# Finally, you are allowed to use the same DataBlock reference for every
# table or you may use a separate DataBlock for each table.
# This depends if you would like functions to be able to access and modify
# the same data or not::
#
# block = ModbusSequentialDataBlock(0x00, [0]*0xff)
# store = ModbusSlaveContext(di=block, co=block, hr=block, ir=block)
#
# The server then makes use of a server context that allows the server to
# respond with different slave contexts for different unit ids. By default
# it will return the same context for every unit id supplied (broadcast
# mode).
# However, this can be overloaded by setting the single flag to False and
# then supplying a dictionary of unit id to context mapping::
#

# 0x01: ModbusSlaveContext(...),
# 0x02: ModbusSlaveContext(...),
# 0x03: ModbusSlaveContext(...),
# }
# context = ModbusServerContext(slaves=slaves, single=False)
#

# request to address(0-7) will map to the address (0-7). The default is
# False which is based on section 4.4 of the specification, so address(0-7)
# will map to (1-8)::
