4.2.3 Address Map
The I/O data store provides storage for all I/O data, either local or received from the
system.
The I/O Store provides eight different “data files”, two bit, two word, two long-word and
two floating point files. In addition each file type supports both inputs and outputs of the
device and data storage for the gateway function.
These files are mapped into the address range as described below.

The addressing utilises standard Modbus protocol formatting as well as being common
for ELPRO protocol.
