Chapter 8. Communication Functions
8.1 Dedicated Protocol Communication
8.1.1 Introduction
MASTER-K120S’s built-in Cnet communication uses only MASTER-K120S main unit for a dedicated communication. That is, it
doesn’t need a separate Cnet I/F module to facilitate the user-intended communication system by utilizing reading or writing of
any area in CPU, and monitoring function.
MASTER-K120S main unit serves as follows:
•
Individual/continuous reading of device
•
Individual/continuous writing of device
•
Reading CPU status
•
Monitor devices registration
•
Executing monitoring
•
1:1 connection (link between MASTER-K’s) system configuration (MASTER-K120S main unit : RS-232C)
Remark
MASTER-K120S built-in communication function supports Cnet communication without any separate Cnet I/F module.
It must be used under the following instructions.
1) Channel 0 of MASTER-K120S main unit supports 1:1 communication only. For 1:N system having master-slave
Format, use RS-485 communication in channel 1 or MASTER-K120S main unit with G7L-CUEC module connected.
G7L-CUEC module supports RS-422/485 protocol.
2) RS-232C communication cable for MASTER-K120S main unit is different from RS-232C cable for KGLWIN in pin
arrangement and from the cable for Cnet I/F module, too. The cable can’t be used without any treatment. For the
detailed wiring method, refer to 8.1.2.
It’s possible to set baud rate type and station No. in KGLWIN.
