ABB PM858K02 3BSE082896R1冗余处理器单元S串行端口状态指示灯ABB PM858K02 3BSE082896R1有三个指示灯，指示CPU上串行端口活动的状态。ABB PM858K02 3BSE082896R1的SNP LED称为CPU363上的PS端口。这是指使用PLC电源上串行连接器的端口。当通过端口传输数据时，此指示灯闪烁。当端口处于非活动状态时，该指示灯熄灭。Ŷ当数据通过端口1（RS-232端口）传输时，P1 LED将闪烁。当端口处于非活动状态时，它将保持关闭状态。Ŷ当数据通过端口2（RS-485端口）传输时，P2 LED将闪烁。当端口处于非活动状态时，它将保持关闭。支持的协议从固件版本9.00开始，无中断SNP成为这些模块上三个串行端口的默认协议。详情请参见第5-13页的“无中断SNP协议”。SNP端口（通过电源连接器）ABB PM858K02 3BSE082896R1

Serial Port Status LEDs TheABB PM858K02 3BSE082896R1have three LEDs that indicate the status of serial port activity on the CPU. Ŷ The SNP LED on the CPU351 and CPU352 is called PS Port on the CPU363. This refers to the port that uses the serial connector on the PLC’s power supply. This LED flashes when data is being transferred through the port. It remains off when the port is inactive. ABB PM858K02 3BSE082896R1 The P1 LED will flash when data is being transferred through Port 1, the RS-232 port. It remains off when the port is inactive. Ŷ The P2 LED will flash when data is being transferred through Port 2, the RS-485 port. It remains off when the port is inactive.Protocols Supported Starting with Firmware Release 9.00, breakfree SNP became the default protocol on the three Serial Ports on these modules. See “Breakfree SNP Protocol” on page 5-13 for details. SNP Port (Through Power Supply Connector) Ŷ SNP slave Ŷ SNP-X slaveABB PM858K02 3BSE082896R1
