在实验过程中遇到的问题

波特率

协调员:38400

传感器:38400

致动器: 9600

当边缘网关和串口服务器同时连接时,在边缘网关的配置程序中,新的连接器应该选择“串口服务器接入”。另外,串口服务器ip是本地局域网中串口服务器的配置IP,串口服务器端口从6001到6004 (RS232),取决于数据连接到哪个串口。

每次断电重新连接时,必须断开与串口服务器连接的串口,否则无法正常启动(正常启动时下方WAN/lan接口的二极管会亮起,如果局域网端口连接到交换机,局域网会闪烁,启动完成后串口服务器上方的PWR会亮起红灯)。然后,重新连接断开的串行端口。小心不要接错线。由于在配置界面中设置了不同的串口波特率,它可能无法正常工作。

对于接ADAM-4017的传感器设备,最好用剥线器多剥一些,再接一点长一点的线,接在电源卡槽上(一般是24V,12V)。

ADAM-4017中的信号通道可以随意连接

例如Vin0、Vin1、Vin2

但相应的Vin0-、Vin1-、Vin2-要按要求接gnd线。

在ADAM-4150,DI0,DI1,DI2等。连接到特定的传感器,而DO0、DO1、DO2等。连接到致动器。

接入方式不固定,测试时可以自由发挥,但比赛时要按要求接入指定位置。
