The E2 provides an address map, which maps the internal register files to addresses.
Addresses are common for ELPRO protocol and for Modbus Protocol. The table also
details the internal IO Store name for each of the address ranges.
The following table shows the basic onboard I/O available in a standard E2 module with
no expansion I/O connected. For a more detailed I/O map (showing the full register
range), see Appendix A at the end of the manual.
