Communication Function MK80S được xây dựng trong Cnet thông tin liên lạc chỉ sử dụng đơn vị cơ sở MK80S cho một thông tin liên lạc chuyên dụng. Nghĩa là, nó không cần một Cnet riêng biệt I / F mô-đun để tạo điều kiện thuận lợi cho các hệ thống thông tin liên lạc của người dùng dự định bằng cách sử dụng đọc hoặc viết của bất kỳ khu vực trong CPU, và chức năng giám sát. MK80S đơn vị cơ sở phục vụ như sau:. | Chapters Communication Function Chapter 8 Communication Function Dedicated Protocol Communication 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 . 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. 8-1 Chapters Communication Function System configuration method According to the method of connection the system using MK80S built-in communication can be composed. 1 Connecting system configuration link between MASTER-K s 1 1 1 connection with general PC a Communication program made by C or BASE computer language on the user s computer or utility program like MMI software can be used. K80S base unit 8-2 Chapters Communication Function 2 1 1 connection with a monitoring device like .
