Chapter 5 System Configuration
Cnet I/F module is used for CPUH and CPUS both. Up to 24 modules can be mounted on the main and expansion bases, and all
24 modules can be used using a dedicated protocol. However, only 8 modules are available to use P2P service.
Various communication systems can be configured via this module in accordance with application fields. This chapter describes
examples of
system configurations which are available or unavailable for the application fields.
5.1 Available System Configurations
5.1.1 1:1 connection (no modem) to PC (HMI)
PC(HMI) and Cnet I/F module are connected via RS-232C or RS-422 channel in 1:1 connection system with PC (HMI) or
PLC not through modem. Most PC(HMI)s are operated as client stations and Cnet I/F modules are operated as sever
stations that respond the request of PC(HMI). Since no modem is applied, communication distance is max.15m via RS-232C
channel and max.500m via RS-422 channel. Operation mode of Cnet I/F module shall be set as agreed with communication
type of PC(HMI).

5.1.2 1:1 dedicated modem connection to PC (HMI)
PC(HMI) and the module are connected through dedicated modem via RS-232C channel in 1:1 connection system. Most
PC(HMI)s are operated as client stations and Cnet I/F modules are operated as sever stations that respond the request of
PC(HMI). Since modem is applied to go through, RS-232C channel shall be set to dedicated modem for long-distance
communication. Operation mode of this module shall be set as agreed with communication type of PC(HMI).
