一线制通讯 communication(communications line communication system)

实验方法: 1写flash 烧flash的时候采用默认的配置 2然后在JTAG方式下面调试 按key1 key 2 3 4 发光管亮灭(Experimental methods: 1 write flash burn flash when using the default configuration of 2 and then in the JTAG debug mode by following key1 key 2 3 4 LED light out)

通过 Modbus 通讯 RS485 型物理链路，或装有适当变换器的其他接口使 Sepam 能 与远程监控系统连接。 Sepam 采用的 Modbus 规约与 RTU Modbus (1) 规约的子集兼容 ( 一个 Modbus 主 机可以同多个 Sepam 单元通讯 )。 Sepam 永远是子机 ( 从站 )。 所有 Sepam 单元均可配置 ACE949-2 ( 二线 ) 或 ACE959 ( 四线 ) 接口与通讯网络 连接。 RS485 和 ACE937 可连接到通讯网络，光纤通讯星形系统。(Communication via Modbus RS485 type physical link, or fitted with suitable converters other interfaces can make Sepam Connection with a remote monitoring system. Sepam uses a subset of the Modbus protocol with RTU Modbus (1) of the Statute compatible (a Modbus master Machine unit can communicate with a plurality of Sepam). Sepam is always a slave (slave). All Sepam unit can be configured ACE949-2 (wire) or ACE959 (four-wire) communications network interface connection. RS485 and ACE937 can be connected to the communications network, fiber-optic communication star system.)
