Correspondence Between the Remote Register and
Address
This section describes the correspondence between the remote register and address of slave modules.
When set with RWrn = D1000 and the network parameters of GX Works2
Ex.
Remote register
RWrn + 0
H
RWrn + 1
H
The slave module requires "Address setting" which specifies the start number assigned in the transmission frame.
The settings are configured in 1-point unit. The addresses of both an input slave module (e.g. input remote I/O module)
and an output slave module (e.g. output remote I/O module) start from 0, and the area later than that number is
occupied corresponding to the number of module points.
Assignment of two 8-point input remote I/O modules
Ex.
Remote register
