ABB PM861AK01 3BSE018157R1控制器模块
产品详情资料：
ABB PM861AK01 3BSE018157R1控制器模块LED指示灯有四个LED指示灯。三个与以太网接口相关：EOK、LAN和STAT。它们可以是ON、OFF、FLASHING LOW或FLASHING fast，以几种不同的组合。GFK-1541《90系列PLC用户手册TCP/IP以太网通信》中详细介绍了这些LED的全部功能。第四个LED，PS PORT，用于CPU的串行端口，与以太网接口无关。当通过PLC电源上的SNP串行端口连接器传输数据时，该LED将闪烁，当端口处于非活动状态时，LED将熄灭。（在一些早期生产的364 CPU上，此LED标记为“SNP”。）ABB PM861AK01 3BSE018157R1并进入维护状态ABB PM861AK01 3BSE018157R1《90系列PLC用户手册的TCP/IP以太网通信》中详细介绍了这些。按键开关这是一个标准的CPU按键开关，在本章前面讨论过。前面板连接器GFK-1541《90系列PLC用户手册TCP/IP以太网通信》中详细介绍了这些端口的全部功能ABB PM861AK01 3BSE018157R1
ABB PM861AK01 3BSE018157R1LED Indicators There are four LED Indicators. Three relate to the Ethernet interface: EOK, LAN, and STAT. These can be ON, OFF, FLASHING slow, or FLASHING fast in several different combinations. The full functionality of these LEDs is detailed in GFK-1541, TCP/IP Ethernet Communications for the Series 90 PLC User’s Manual. The fourth LED, PS PORT, is for the CPU’s serial port and is not related to the Ethernet interface. This LED will flash while data is being transferred through the SNP serial port connector on the PLC power supply, and will stay off when the port is inactive. (On some early production 364 CPUs, this LED is labeled “SNP.”) All Series 90-30 CPUs have this standard serial port. Ethernet Restart Pushbutton This pushbutton performs four functions: LED test, Restart, Restart and enter Software Load state, aABB PM861AK01 3BSE018157R1nd Restart and enter Maintenance state. These are detailed in GFK-1541, TCP/IP Ethernet Communications for the Series 90 PLC User’s Manual.Keyswitch This is a standard CPU keyswitch, discussed earlier in this chapter. Front Panel Connectors The full functionality of these ports is detailed in GFK-1541, TCP/IP Ethernet Communications for the Series 90 PLC User’s ManualABB PM861AK01 3BSE018157R1
