RMM: Rnet Master Module ⊙
Rnet I/F module equipped at the basic base’s I/O
RSM: Rnet Slave Module⊙
Rnet I/F module equipped at the CPU slot of basic base
※ Rnet I/F module and Fnet I/F module use same communication method (RMM does same rule with
FMM, RSM does same rule with FSM.)
⊙ Local station
Station that is connected with GMWIN/KGLWIN for the user to monitor/debug the program in the same
network
⊙ Remote station
The opposite concept to local station, the other station to communicate with local station
⊙ Remote I/O station
Input/output area that the remote communication module of PLC system instead of CPU of PLC
refreshes I/O module mounted on remote station by receiving I/O data from master station.
Rnet ⊙
Fieldbus is the lowest network connecting the control device and electric device and adopts the 3 layers
among OSI 7 layer. 3 layers consists of physical layer which consists of H2(1 Mbps electric), H1 (31.23
Kbbs electric), optical, and wireless, etc., the data link layer which adopts scheduled and circulated
token bus, the application layer which plays a role of application, and additional user layer.
Token ⊙
The right to transmit data of self station through controlling the right of accessing to physical medium
Rnet ⊙ station no.
Station no. of Rnet communication module (G3L-RUEA….etc.) Station no. of Rnet module is set by the
switch attached on the module and this is used on all service including the high-speed link.
