在單一配置中，PM864處理器單元的性能數(shù)據(jù)理論上峰值是PM860的兩倍。然而，有用的持續(xù)性能改進(jìn)要低一點(diǎn)，并且在一定程度上取決于實(shí)際的應(yīng)用程序，但與PM860相比，可以預(yù)期為10%至50%。在冗余配置中，執(zhí)行性能略低于單一配置。在冗余配置中，從主CPU到備份CPU的切換時(shí)間小于10毫秒。關(guān)鍵功能?MPC862P微處理器以96 MHz運(yùn)行。?32 MB RAM，帶內(nèi)部或外部電池備份設(shè)施。?12 x S800 I/O單元可以連接到電氣模塊總線。?四個(gè)板載通信端口：–CN1+CN2，以太網(wǎng)端口（IEEE 802.3，10BaseT）–COM3，帶調(diào)制解調(diào)器支持的串行端口（RS-232C）–COM4，用于維修工具的串行端口冗余控制鏈路，用于冗余配置。?高完整性控制器（帶SM810和認(rèn)證軟件）-過(guò)電壓保護(hù)-內(nèi)部電壓監(jiān)控-在非SIL和SIL1-2應(yīng)用程序中運(yùn)行應(yīng)用程序代碼-支持S800 I/O高完整性
The PM864 processor unit, in single configuration, has performance data which theoretically peaks at twice the performance compared to the PM860. The useful sustained performance improvement is, however, a bit lower and somewhat dependent on the actual application program but can be expected to be 10 to 50% compared to PM860. In redundant configuration the execution performance is somewhat lower than in single configuration. Switch over time from Primary CPU to Backup CPU, in redundant configuration, is less than 10 ms.Key Features ? MPC862P Microprocessor running at 96 MHz. ? 32 MB RAM with internal or external battery back-up facility. ? 12 x S800 I/O units can be connected to the electrical ModuleBus. ? Four on-board communication ports: – CN1 + CN2, Ethernet ports (IEEE 802.3, 10BaseT) – COM3, serial port (RS-232C) with modem support – COM4, serial port (RS-232C) for service tool ? Basic communication is extendable by using additional communication interface units. ? Redundancy Control Link, for use in redundant configuration. ? High Integrity Controller (with SM810 and certified software) – Overvoltage protection – Internal voltage supervision – Runs application code in non-SIL and SIL1-2 applications – Supports S800 I/O High Integrity
