Protocol-RS-232/422/485标准 引: 通常的微处理器都集成有1路或多路硬件UART通道,可以非常方便地实现串行通讯。在工业控制、电力控制、智能仪表等领域中,也常常使用简便易用的串行通讯方式作为数据交换的手段。 但是,在工业控制等环境中,常会有电气噪声干扰传输线路,使用RS-232通讯时经常因为外界的电气干扰而导致信号...
本通訊協定(Protocol)是永宏PLC主機上各通訊埠在標準通訊模式下均適用之通訊協 定,任何對PLC之資料存取(自PLC內部讀出或由外界寫入PLC)或運作、控制等,除在 硬體連線及通訊參數設定必需通訊雙方一致外,在通訊訊息格式(Messageformat)方面亦 必需符合本通訊協定之格式PLC才能正確回應。在介紹通訊協定之前首先...

An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station (Figure 6) to a receiving station (Figure 7). Each of the stations has a control counter (310)...
