Modbus to FifeNet Data
In each of the three configurations (single-, dual-, or triple-drive CDP-01), the Modbus to FifeNet data
is the same. The table below shows the configuration mapping for data traveling from Modbus to
FifeNet. The data can be accessed as coils or contacts (bits) or 16-bit words. For example, the 7
words below appear as 112 bits or 7 registers. The control matrix data on data word 1 is present so
that if it is mapped to the parallel input for the CDP-01, a great deal of control can be exercised without
a special state machine in the CDP-01. If this control is insufficient, the data capabilities on Registers
2 through 6 are provided for custom applications using state machine interpretation.
