3.2.3 CM 772F PROFIBUS-DP Master Interface

CM 772 RROFIBUS主站接口

 

 

 

 

     The number of possible slaves is determined by the total number of input and output bytes. As a rule, many PROFIBUS PA devices (few I/O bytes) or a limited number of remote I/O (many I/O bytes) can be connected to the bus.

     能够接入的从站数量由输入和输出总字节数决定。通常，许多 PROFIBUS PA 设备（带有很少 I/O 字节）或数量有限的远程 I/O（许多 I/O 字节）可以连接到总线。

LED status displays

LED状态显示灯

      After having been switched on, the CI 772 PROFIBUS module performs a self-test during power-up. If the test is successfully performed, the yellow LED RDY lights up, if not, the LED starts to flash and the initialization is aborted. If the LED RDY does not light up at all, the PROFIBUS module is probably defective. During initialization, with newly configured modules or after a change of the operating mode, all LEDs may light up briefly before reaching the defined status.

        送电后，CI 772模板开始自检。如果自检成功执行，黄色的RDY(准备好）灯亮起，如果自检没通过，starts闪烁，终止初始化工作。如果RDY灯没有亮起，可能是这个PROFIBUS模块由问题。在初始化过程中，使用新配置的模块或在操作模式更改后，所有 LED 可能会在达到定义状态之前短暂亮起。

LED LED灯	Color 颜色	Status 状态	Meaning 含义
PWR 电源灯	Green 绿色	ON 亮	Voltage is applied 已送电
		OFF 灭	No voltage is applied 未送电
RDY 准备好	Yellow 黄色	ON 亮	Coupler ready for operation 耦合器准备工作
		Cyclic flashing 周期闪烁	Boot loader is active 耦合器准备就绪
		Non-cyclic flashing 无周期闪烁	Hardware or system error 硬件或系统错误
		OFF 灭	Defective hardware 硬件缺陷
RUN 运行灯	Green 绿色	ON 亮	Communication on 通讯中
		Cyclic flashing 周期闪烁	Ready for communication 准备通讯
		Non-cyclic flashing 无周期闪烁	Parameterization error 参数化错误
		OFF 灭	No communication 没有通讯
STA 状态灯	Yellow 黄色灯	ON 亮	DP master: data or token are transmitted via the network DP主站：数据或令牌通过网络传输
		OFF 灭	DP master: No token DP主站：没有令牌
ERR 错误灯	Red 红色	ON 亮	PROFIBUS error PROFIBUS错误
		OFF 灭	No error 没有错误
