GENERIC 26D023003数字量控制板卡
1.产 品 详 情 资 料：
在单一配置中，PM864处理器单元的性能数据理论上峰值是PM860的两倍。然而，有用的持续性能改进要低一点，并且在一定程度上取决于实际的应用程序，但与PM860相比，可以预期为10%至50%。在冗余配置中，执行性能略低于单一配置。在冗余配置中，从主CPU到备份CPU的切换时间小于10毫秒。关键功能•MPC862P微处理器以96 MHz运行。•32 MB RAM，带内部或外部电池备份设施。•12 x S800 I/O单元可以连接到电气模块总线。•四个板载通信端口：–CN1+CN2，以太网端口（IEEE 802.3，10BaseT）–COM3，带调制解调器支持的串行端口（RS-232C）–COM4，用于维修工具的串行端口冗余控制链路，用于冗余配置。•高完整性控制器（带SM810和认证软件）-过电压保护-内部电压监控-在非SIL和SIL1-2应用程序中运行应用程序代码-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
