NI PXI-6722 PXI模拟输出模块
产品详情资料：
NI PXI-6722 PXI模拟输出模块NI PXI-6722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。所有90-30系列CPU都有此标准串行端口。以太网重启按钮此按钮执行四个功能：LED测试、重启、重启并进入软件加载状态，以及重启并进入维护状态。GFK-1541《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CPU按键开关，在第3-15页讨论。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。Station Mgr-此连接器用于连接终端或终端仿真器，以访问以太网接口上的Station Manager软件。NI PXI-6722端口1相同的引脚。IC693CBL316电缆可用于访问此端口。有关此电缆的数据表，请参阅第10章。NI PXI-6722
NI PXI-6722The 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. 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, and 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 on page 3-15. 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 Manual.Station Mgr - This connector is used to connect a terminal or terminal emulator to access the Station Manager software on the Ethernet Interface. This RJ-11 connector has the same pinout as Port 1 of the CNI PXI-6722 shown in Table 5-5. The IC693CBL316 cable can be used to access this port. See Chapter 10 for a data sheet on this cable.NI PXI-6722
