D20 EME輸入板卡,GE英文說明D20 EME
CPU板包含微處理器和RAM內存、實時時鐘、LED指示燈、INITpush按鈕和CompactFlash接口。PM866/PM866A控制器的底板有兩個用于連接控制網絡的RJ45以太網端口（CN1、CN2）和兩個RJ45串行端口（COM3、COM4）。其中一個串行端口（COM3）是帶有modemcontrol信號的RS-232C端口，而另一個端口（COM4）是隔離的，用于連接配置工具。
D20 EME輸入板卡控制器支持CPU冗余以獲得更高的可用性（CPU、CEX總線、通信接口和S800 I/O）。簡單的DIN導軌連接/拆卸程序，使用獨特的滑動和鎖定機制。所有基板都提供了一個唯一的以太網地址，該地址為每個CPU提供了一個硬件標識。地址可以在附在TP830基板上的以太網地址標簽上找到。功能和好處ISA安全認證-更可靠、更簡單的故障診斷程序模塊化，考慮到逐步擴展IP20級保護而無需機柜的要求，控制器可以配置800xA control builder。控制器具有完整的EMC認證分段CEX總線，使用一對BC810/BC820硬件，基于優化通信連接標準（以太網、PROFIBUS DP等），內置冗余以太網通信端口The CPU board contains the microprocessor and RAM memory, a real- time clock, LED indicators, INITpush button, and a CompactFlash interface. The base plate of the PM866 / PM866A controller has two RJ45 Ethernet ports (CN1, CN2) forconnection to the Control Network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C portwith modemcontrol signals,whereas the other port(COM4) is isolated and used for the connection of a configuration tool. The controller supports CPU redundancyfor higher availability(CPU, CEX-Bus,communication interfaces and S800 I/O). Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism. All base plates are providedwith a unique Ethernet address which provides every CPUwith a hardware identity. The address can be found on the Ethernet address label attached to the TP830 base plate.Features and benefits ISA Secure certified - Read more Reliability and simple fault diagnosis procedures Modularity, allowing for step-by-step expansion IP20 Class protection withoutthe requirementfor enclosures The controllercan be configuredwith 800xA control builder The controller has full EMC certification Sectioned CEX-Bus using a pair of BC810 / BC820 Hardware based on standards for optimumcommunication connectivity(Ethernet, PROFIBUS DP, etc.) Built-in redundant Ethernet Communication ports
