Fixed Mapping means each module has its own Modbus registers for
data transfer independent of the I/O bus constellation description. For
details see.
Dynamic mapping means the structure of the IO Date is dependent on
the I/O bus constellation. Each I/O bus expansion module starts directly
after the module before on the next Word adress.

)
If none of the parameters is set all masters / clients in the network have
read and write rights on the CI52x-MODTCP device and its connected
expansion modules.
If at least one parameter is set only the configured masters / clients have
write rights on the CI52x-MODTCP device, all other masters / clients still
have read access to the CI52x-MODTCP device.
