6.5.1 Assigning I/O extension modules to the register
You can use the white thumbwheel on the I/O extension module to assign an I/O MAP
address in the Modbus memory map. Example: if you set the thumbwheel of an input
module to I/O MAP address = 01, the register assignment is 30010.
6.6 Modbus memory map
The I/O data from the extension modules is stored in an internal register, the Modbus mem-
ory map. The Modbus memory map is located in the master wireless module with
RADID=01. The data here can be read or written by a Modbus master.
The following process data tables for the individual extension modules show at what loca-
tion the I/O data is stored in the Modbus memory map. You can find a complete overview of
the Modbus memory map from page 79 onwards.
The RSSI signal register can be found from page 82 onwards.
