The non-modifiable parameter Restore module parameters in the web server will be set to
Yes as soon as the network adapter has sent saved parameters to the modules.

0x27FE Number of Entries in the Current Module List

This displays the number of modules that were connected when the network adapter was
started.

0x27FF Number of Entries in the Reference Module List

This displays the number of modules that were entered the reference list.
0x2800 – 0x287F Reference Module List
Each module identifier is made up of 4 bytes (2 registers). If a 1 is set in register 1132, the
reference module list must be identical to the current module list before the data exchange
can begin.
0x2A00 – 0x2A7F Current Module List
Each module identifier is made up of 4 bytes (2 registers) (refer to the Overview of module
IDs). The modules that were connected when the network adapter was started are entered
here. To simplify configuration, the current module list can be copied into the reference
module list.
0x2B00 – 0x2B7F Module Offsets of Process Data
For each module there are two registers reserved to indicate the offset between the start
address within the packed process data and the address 0x0000: The first register indicates
the bit-offset of the outputs, the second one indicates the bit-offset of the inputs. Thus, it is
possible to use this information directly for the access to coils or Discrete Inputs. Converting
the address syntax is necessary for a register- wise access (refer to the table "Implemented
Modbus functions").
In case there are no outputs or inputs, the register entry is 0xFFFF.
0x8000 – 0x87FF Process Data Inputs
For each module a data length of 64 bytes (32 registers) is reserved.
Example: Module 3 starts at address 0x8040.
