INSTALLATION
Use the Installation Base Model: R3-BSx, or Model: R3-
BSWx for free I/O address capability.
Before mounting the Network Interface Module R3-GM1
onto the base, be sure to configure the module as explained
below.
■DATA ALLOCATION
UsethesideDIPSW1tosetthenumberofslotswhichthe
module is assigned to.
See“TRANSMISSIONDATADESCRIPTIONS.”
■NODE ADDRESS & BAUD RATE
See“COMPONENTIDENTIFICATION.”
■NETWORK SLOTS ON THE BASE
WithModelR3-BSxbase,mounttheI/OModulesfromthe
left end (I/O 1) to the right in order that the Network Mod-
ule assigns data areas from I/O 1.
Network Module(s) and Power Module are mounted basi-
cally at the right end though technically they could be
mounted in any position.
WithModelR3-BSWxbase,thereisnolimitationinmount-
ing positions as I/O address can be assigned freely to each
module using rotary switches equipped on the base.
It is available to assign the module to max. 8 slots. The as-
signed slots numbers can not be used again for the real I/O
moduleswhichneedtobemountedonthesamebase.Don’t
set the interface module for more than 16 slots as it can not
read the data for more than 16 modules.
