RELIANCE 0-57C406-E工控控制卡件
1.产 品 详 情 资 料：
RELIANCE 0-57C406-E注意：不允许使用不同CPU类型进行扩展操作。在正常操作期间，HSB冗余系统中的主单元和辅助单元必须具有相同的CPU型号。HSB冗余系统的一次和二次单元可以在有限的时间内具有不同的型号，仅用于系统升级。不同冗余对中较高性能CPU的故障等待时间可能需要增加以允许同步。RX7i通信功能包括：▪ 开放式通信支持包括以太网、RELIANCE 0-57C406-EGenius和串行协议。▪ 内置10/100mb以太网接口，通过自动感应开关连接双RJ45端口，用于上传、下载和在线监控。这消除了对机架到机架交换机或集线器的需求。CPU以太网接口通过网络浏览器提供基本的远程控制系统监控，并允许总共多达16个网络服务器和FTP连接。有关以太网接口功能的详细信息，请参阅PACSystems RX7i和RX3i TCP/IP以太网通信用户手册，GFK-2224。▪ 两个串行端口，一个RS-232和一个RS-485。▪ 一个RS-232隔离以太网Station Manager串行端口。RELIANCE 0-57C406-E
RELIANCE 0-57C406-ENote: Extended operation with dissimilar CPU types is not allowed. During normal operation, the primary and secondary units in an HSB redundancy system must have the same CPU model type. The primary and secondary units of an HSB redundancy system can have dissimilar model types for a limited time, for the purpose of system upgrade only. Fail wait times for the higher performance CPU in a dissimilar redundant pair may need to be increased RELIANCE 0-57C406-Eto allow synchronization. RX7i communications features include: ▪ Open communications support includes Ethernet, Genius, and serial protocols. ▪ A built-in 10/100mb Ethernet interface that has dual RJ45 ports connected through an autosensing switch for upload, download and online monitoring. This eliminates the need for rack-to-rack switches or hubs. The CPU Ethernet Interface provides basic remote control system monitoring from a web browser and allows a combined total of up to 16 web server and FTP connections. For details on Ethernet Interface capabilities, refer to PACSystems RX7i & RX3i TCP/IP Ethernet Communications User Manual, GFK-2224. ▪ Two serial ports, one RS-232 and one RS-485. ▪ An RS-232 isolated Ethernet Station Manager serial port.RELIANCE 0-57C406-E
