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。
