RELIANCE 0-57C406-E工控控制卡件
1.產 品 詳 情 資 料：
RELIANCE 0-57C406-E注意：不允許使用不同CPU類型進行擴展操作。在正常操作期間，HSB冗余系統中的主單元和輔助單元必須具有相同的CPU型號。HSB冗余系統的一次和二次單元可以在有限的時間內具有不同的型號，僅用于系統升級。不同冗余對中較高性能CPU的故障等待時間可能需要增加以允許同步。RX7i通信功能包括：? 開放式通信支持包括以太網、RELIANCE 0-57C406-EGenius和串行協議。? 內置10/100mb以太網接口，通過自動感應開關連接雙RJ45端口，用于上傳、下載和在線監控。這消除了對機架到機架交換機或集線器的需求。CPU以太網接口通過網絡瀏覽器提供基本的遠程控制系統監控，并允許總共多達16個網絡服務器和FTP連接。有關以太網接口功能的詳細信息，請參閱PACSystems RX7i和RX3i TCP/IP以太網通信用戶手冊，GFK-2224。? 兩個串行端口，一個RS-232和一個RS-485。? 一個RS-232隔離以太網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
