1) Master Module
Rnet I/F module to be installed on I/O location of the basic base.
2) Slave Module (RSM : Rnet Slave Module)
Rnet I/F module to be installed on CPU location of the basic base or Smart I/O Rnet.
3) Local Station
Station directly connected with XG5000, XG5000 in the same network including CPU for user to
download, monitoring and debug programs.
4) Rnet
Fieldbus, as the lowest network to connect control device with relay device has adopted 3 layers among
OSI’s 7 layers. The 3 layers are composed of physical layer configured with H2(1Mbps electric), H1
(31.23Kbbs electric), optic/wireless, etc., data link layer with Scheduled and Circulated Token bus and
application layer in charge of application function where user layer is adopted additionally.
5) Token
It is a right to send data of self-station by access right control over Physical Medium.
6) Repeater
It is used to extend cable length in electric communication network, which extends communication
distance by revival and amplification of electric communication signals.
7) Manchester Biphase-L
It is a data modulating method used in Rnet. Data is sent as encoded by Manchester-l Code and
the data received as encoded by Manchester is converted as decoded.
8) Reset Individual Module
It is used to initialize if an error occurs on the communication module. It operates Reset operation
selecting the [Online] [Reset/Clear] [Reset Individual Module] by XG5000. Then PLC do Restart
operation to initialize.
