上一次雷莫时，您与CPU之间的距离不得超过英尺。必须在整个系统中使用雷莫重新设计的驾驶室类型。这一要求的例外情况是，可将预安装的驾驶室ICCBL用作Y型适配器，以简化与s之间的菊花线连接相关的驾驶室总成。可在ICCBtc中的驾驶室apr中找到有关与Remo s一起使用的驾驶室的信息。数据表。。扩展或远程系统的安装和硬件8月Q端接要求当通过总线扩展系统连接两个或多个时，扩展总线必须正确端接。终止扩展总线的最常见方法是在系统中距离CPU扩展或Remo最远的最后一个开放位置安装一个终止resisr pack ICACC。树脂包在一个。尽管终端树脂包随ea一起发货，但只有最后一个需要安装此终端。可以丢弃未使用的终端包。预压脚机驾驶室ICCBL在驾驶室一端的内部具有端接电阻d。如果一个系统中只需要一个扩展机架，并且需要一个脚驾驶室链路，则可以使用该驾驶室。在这种情况下，不需要ICACC resisr pack。此外，带有内置树脂的简易驾驶室将消除对ICACC树脂包的需求。断电单独扩展或雷莫扩展或雷莫可单独断电，而不影响其他设备的运行；但是，在中的故障选项卡中，由于loss_of_故障而关闭发电机。当出现此故障情况时，直到重新通电并恢复所有，丢失的不会被扫描。有关通电和断电顺序的更多信息，请参阅《控制器参考》中的apr。背板所有三种类型的背板都有专用总线。远程背板上的信号是光学耦合的，并且提供了隔离开关DCDC电源转换器，隔离来自其他背板的信号。电源总线连接中的电源。通过该总线将CPU与s通信。该总线通过总线扩展和驾驶室连接到扩展和Remo机架中的总线。专用智能总线仅存在于CPU上；因此，某些特殊的输入选项，如协处理器PCM字母数字显示协处理器ADC和CMM控制ICCMM仅在CPU中工作。系统中的Q apr机架号DIP Swit on Expansion and Remo s Ea用唯一的编号和机架号标识。扩展和远程的机架编号通过在插槽的正上方设置DIP开关位置来确定。机架编号必须始终存在，并且在默认情况下分配给CPU机架，CPU没有此DIP开关。机架无需连续编号，但为了一致性和清晰性，请记住，机架编号不应跳过。系统内的机架号不得重复。以下选项卡显示了机架编号部分的DIP开关位置。表。机架编号部分开关设置机架编号DIP开关打开关闭打开关闭关闭关闭关闭打开关闭打开打开关闭关闭打开打开打开关闭打开闭合关闭关闭关闭闭合关闭关闭打开闭合闭合打开打开打开机架编号仅对CPU及更高版本有效。使用的特定CPU决定了如何允许扩展和远程：和CPU总共支持四个扩展和或远程机架。和CPU总共支持七个扩展和或Remo机架。Ea在DIP开关上方有一个标签，显示每个机架编号的设置。下图显示了该DIP swit包，其中包含机架编号secd的示例。不使用圆珠笔设置DIP开关。一般来说，最好避免使用铅笔组DIP开关，因为铅笔中的图形会破坏开关。DIP SW扩展架#X关闭G E F anu c底座插槽扩展控制器关闭开关按下右侧X X X X X X X X图。机架编号部分开关显示为机架分段
You do not exceed the foot mer cab distance from the CPU the last Remo . The cab type remended for use with Remo s must be used throughout the sysm. The exception this requirement is that the pred foot mer cab ICCBL can be used as a Wye adapr simplify the cusm cab assembly associad with the daisy ain connections between s. Infortion on building cabs for use with Remo s can be found in the Cabs apr in the ICCBtc. data sheet.. Installation and Hardware August Q rmination Requirement for Expansion or Remo Sysm When two or more s are connecd via the Bus Expansion Sysm the Expansion Bus must be properly rminad. The most mon method of rminating the Expansion Bus is by installing a rmination resisr pack ICACC on the open on the last most distant from the CPU Expansion or Remo in the sysm. The resisr pack is physically mound inside of a . Although a rmination resisr pack is shipped with ea only the last in the ain needs have this rmination instald. Unused rmination packs can be discarded. The pred foot mer cab ICCBL has rmination resisrs d inside the on one end of the cab. This cab can be used if only one expansion rack is needed in a sysm and a foot cab link is required the ICACC resisr pack is not needed in this case. Also a cusmbuilt cab with builtin resisrs would elimina the need for the ICACC resisr pack. Powering Down Individual Expansion or Remo s Expansion or Remo s can be powereddown individually without affecting the operation of other s; however powering off a generas a loss of LOSS_OF_ fault in the Fault Tab for ea in the . When this fault condition occurs and until the is powered back on and all s recovered the lost s are not scanned. For more infortion on the powerup and powerdown sequence see apr in the Controlr Reference . Backplane The backplane on all three types of s has a dedicad bus. The signals on the remo backplane are optically coupd and an isolad DCDC power supply converr is provided isola the signals from other backplanes. Power bus connects the power supply s the s in the . bus the CPU municas with s over this bus. This bus is connecd the busses in Expansion and Remo racks via the Bus Expansion s and cabs. Special Inlligent bus exists only on a CPU ; therefore certain special inlligent option s su as the Coprocessor PCM Alphanumeric Display Coprocessor ADC and CMM Control ICCMM only work in a CPU . Q apr s Rack Number DIP Swit on Expansion and Remo s Ea in a sysm is identified with a unique number cald a Rack Number. Rack Numbers for Expansion and Remo s are secd by setting a DIP swit locad on ea directly above the for Slot . Rack number must always be present and is assigned by default the CPU rack the CPU does not have this DIP swit. Racks do not need be contiguously numbered although for consisncy and clarity it is remended that rack numbers not be skipped use not . Rack numbers must not be duplicad within a sysm.
