通信端口和接口第241頁表49中描述了通信端口和界面的技術(shù)數(shù)據(jù)。內(nèi)存內(nèi)容由內(nèi)部或外部電池單元（SB821）備份。關(guān)于備份時(shí)間，請(qǐng)參閱第261頁表61。如果在CPU正常通電后安裝了電池，允許激活內(nèi)存?zhèn)浞莨δ?，則第261頁表格61中的數(shù)字有效。內(nèi)部電池最短235小時(shí)外部電池SB821最短24周外部電池SB822注：空電池的充電時(shí)間約為7小時(shí)。當(dāng)充滿電的電磁兼容性和電氣安全PM865/TP830滿足EMC指令89/336/EEC中規(guī)定的要求時(shí)，至少3周。有關(guān)電氣安全的更多信息，請(qǐng)參閱附錄D，指令注意事項(xiàng)。性能數(shù)據(jù)PM865處理器單元，在單一配置中，其性能數(shù)據(jù)理論上達(dá)到峰值，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。
Communication Ports and Interfaces Technical data for communication ports and interfaces is described in Table 49 on page 241.The memory content is backed up with either an internal or external battery unit (SB821). For back-up time see Table 61 on page 261.The figures in Table 61 on page 261 are valid if the batteries have been installed after a normal CPU power-up, allowing for the memory back-up function to be activated.Internal battery Minimum 235 hours External battery SB821 Minimum 24 weeks External battery SB822 Note: Recharge time for an empty battery is approximately 7 hours. Minimum 3 weeks when fully charged Electro-magnetic Compatibility and Electrical Safety PM865/TP830 meets the requirements specified in EMC Directive 89/336/EEC. For more information regarding electrical safety, see Appendix D, Directive Considerations.Performance Data The PM865 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.
