本讲主要介绍CP1H的通信功能及应用,必要时,会提及CP1E、CP1L。1功能介绍CP1H/L有两个串口,即串口1、串口2。可选插件CP1W—CIF01将串口配置成RS232C,或选CP1W—CIF11/12将串口配置成RS422A/485,还可选CP1 W—CIF41将串口配置成以太网接口。CP1E—E基本型没有串口,而CP1E—N应用型内置一个串口,且CP1E—N 30点、40点的CPU可
This talk mainly introduces the communication function and application of CP1H, if necessary, will refer to CP1E, CP1L. 1 Function introduction CP1H / L has two serial ports, namely serial port 1, serial port 2. Optional plug-in CP1W-CIF01 The serial port is configured as RS232C, or choose CP1W-CIF11 / 12 The serial port is configured as RS422A / 485, optional CP1 W-CIF41 The serial port is configured as an Ethernet interface. CP1E-E basic without serial port, and CP1E-N application built a serial port, and CP1E-N 30 points, 40 points CPU
