10.2.3 Input Register
Input Register allows the Modbus mapping of Fieldgate SWG70 and the connected HART devices.
As Fieldgate SWG70 supports extended registers, values are normally assigned the Input Registers
with the reference addresses 300001 to 365536 but for some Modbus systems the mapping must
be made to the Holding Registers with the reference addresses 400001 to 465536, see Read
Modbus Registers Mode in Chapter 10.2.1. The reference addresses are obtained by adding the
register number to 300,000 or 400,000 respectively. The dialogue checks for completeness of
entries (line turns red if not correctly filled out) as well as double assignment to the registers.
