Chapter 8 Communication Function
8.1 Dedicated Protocol Communication
8.1.1 Introduction
MK80S’ s built-in Cnet communication uses only K7 base 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.
MK80S base 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 K’ series) system configuration (K7 base unit:
RS-232C)
Remark
K7 built-in communication function supports Cnet communication without any separate Cnet module. It
must be used under the following instructions.
1)
K7 base unit supports 1:1 communication only. for 1:N system having master-slave Format, use
K7 base unit with G7L-CUEC module connected. G7L-CUEC module supports RS-422/485 protocol.
2)
RS-232C communication cable for K7 base unit is different from RS-232C cable for KGL_WIN in pin
arrangement and from the cable for Cnet module, too. The cable can’ t be used without any treatment. For
the detailed wiring method, refer to 8.1.2.
3)
It’ s possible to set baud rate type and M area size in KGL_WIN. For the detailed information, refer to the
appendix or KGLWIN manual.
