英文資料
Figure 5-3. CPU Serial Port Connector on Power Supply ? This serial port is RS-485 compatible, and uses the GE Fanuc SNP (Series Ninety Protocol) protocol (slave only). Breakfree SNP became the default protocol on all serial ports on the Series 90-30 CPUs, starting with firmware release 9.00 for CPUs 350–364, and firmware release 8.20 for CPUs 311–341. For details, see page 5-13. ? The serial port connector is only functional in a power supply that is installed in a baseplate that also contains the CPU. It is not functional on a power supply that is installed in an expansion or remote baseplate. ? Any device connected to the serial port that uses +5 VDC power from the Series 90-30 power supply must be included in the calculation for maximum power consumption (see the heading “Power Supply Loading Calculations” in Chapter 12). ? All Series 90-30 CPUs have this serial port arrangement. The 351, 352, and 363 CPUs have additional serial ports, described in a later section of this chapter.NI PXIe-5114
