Safety Instructions for Design Process
Safety Instructions on Installation Process
Use PLC onlyin the environment specified in PLC manual or general standard of datasheet.
If not, electric shock,fire, abnormal operation of the product maybe caused.
Before install or remove the module, be sure PLC power is off. If not, electricshockor damage
ontheproductmaybe caused.
Be sure that every module is securely attached after adding a module or an extension
connector. If the product is installed loosely or incorrectly, abnormal operation, error or dropping
may be caused. In addition, contact failures under poor cable installation will be causing
malfunctions as well.
Makesure that the I / O connector is securely fastened. It maycause wrong input or output.
Caution
Design the analog input / output signal or pulse input / output line at least 100mm away
from high voltage line or power line so that it is not affected by noise or magnetic field
change. It maycausemalfunction dueto noise.
If there is a lot of vibrationin the installation environment, take measures to prevent
direct vibration from being applied to the PLC. It maycauseelectricshock,fire ormalfunction.
If metallic dustis present in the installationenvironment, take measures to prevent
metallic dust from entering the product. Itmaycauseelectricshock,fireormalfunction.
Caution

Safety Instructions for Wiring Process
Check rated voltages and terminal arrangements in each product prior to its wiring
process. Applying incorrect voltages other than rated voltages and misarrangement among
terminalsmaycausefire or malfunctions.
Secure terminal screws tightlyapplying with specified torque.If thescrewsgetloose,short
circuit, fire or abnormal operation may be caused. Securing screws too tightly will cause
damagestothemoduleormalfunctions,shortcircuit,anddropping.
Be sure to earth to the ground using Class 3wires for PE terminals which is exclusively
used for PLC. If the terminals not grounded correctly, abnormal operation or electric shock
maybecaused.
Don’t let any foreign materials such as wiring waste inside the module while wiring,
whichmaycausefire,damageonthe product orabnormaloperation.
Caution
Prior to wiring works, make sure that every power is turned off. If not, electric shock or
damageontheproductmaybe caused.

Chapter 1 Introduction
1.1 What is Rnet?
This manual of Rnet I/F module is prepared to describe XGB of dedicated remote net (here in after
referred to as Rnet I/F module). XGB Rnet I/F module is composed of data link layer and physical layer
in OSI 7 layers. Rnet system controls I/O data from the sensor of field level and manages the data
conveniently. Rnet I/F module supports a speed of 1Mbps by using dedicated cable for Rnet, up to 32
stations (including master) and provides convenience of data Tx/Rx for users by means of XG5000
parameters setting, through LS dedicated network.

2) It describes about the number of module and position that can be installed in a single CPU module.
Rnet master I / F module can be mounted up to two modules, regardless of main unit type.
Eight kinds of main units (XBC-U, XBC-H, XBC-SU, XEC-U, XEC-H, XEC-SU, XBM-S,XBM-H)
can use Rnet master I / F module. Please consider the supported number of communication
modules per main unit when PLC sytem is organized. In addition, high-speed link function is only
used and P2P function is not used in XG5000.
