Chapter 8 Communication Function
8.1 Dedicated Protocol Communication
8.1.1 Introduction
MK80S’s built-in Cnet communication uses only MK80S 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 MASTER-K’s) system configuration (MK80S base unit:
RS-232C)
Remark
MK80S built-in communication function supports Cnet communication without any separate Cnet module. It
must be used under the following instructions.
1)
MK80S base unit supports 1:1 communication only. for 1:N system having master-slave Format, use
MK80S base unit with G7L-CUEC module connected. G7L-CUEC module supports RS-422/485 protocol.
(10-point main unit includes RS-485 communication terminal, so 1:N system can be configured without
G7L-CUEC module)
2)
RS-232C communication cable for MK80S 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.
