用户程序的内存量取决于如何为单词内存配置mu。可配置内存在Logicsr版本中具有limid支持。并在控制版本中完全支持K R字、K AI字和K AQ字。以及所有版本的lar VersaPro和CIMPLICITY ine Edition Logic Developer。Q apr CPU附加串行端口CPU CPU CPU虽然所有CPU都有一个通过电源上的访问的串行端口，但CPU CPU和CPU ea都有两个附加串行端口。这些附加串行端口的s堆在CPU的前面。这两个内置串行端口消除了CPU跨背板访问串行端口的需求，从而提高了系统性能。这两个端口支持SNPSNPX sr和从属Procol，请参见第页的Breakfree SNP Procol。固件版本中的RTU从程序。和lar以及固件版本中的串行功能。这让你创造了一个cusm系列。有关如何使用这些端口的说明，可以在Serial C或lar中找到。FloatingPoint th所有CPU都可以使用整数。整数集由包括零在内的所有正负who数组成。浮点运算的特点是CPU可以处理小数和整数。它还提供三角对数指数和弧度转换函数。浮点th也称为实数th。由于内置的协处理器ip，CPU和CPU一直具有基于硬件的浮点th功能。从CPU固件更新开始。CPU组中的所有其他CPU都具有基于固件的浮点功能。尽管CPU和CPU的基于硬件的浮点型与基于固件的类型之间存在速度差异，但这对任何用户来说都不重要。对于速度性能很重要的应用程序，CPU和CPU是最好的选择。浮点指令在CPU指令集参考K或lar中解释。闪存所有的CPU都内置了闪存，它有两个用途：它提供CPU固件的虚拟存储。它为您提供了在nvolati闪存中存储程序配置和注册数据的选项。使用此内存的两种方法是：作为用户内存的板载备份副本，尽管我们仍然记得您保留了p程序文件夹的单独备份副本，并在学期内运行。有关详细信息，请参阅apr。Keyswit所有CPU都有一个Keyswit；然而，某些版本的CPU固件不支持所有keyswit功能，请参阅本节前面的“取消CPU版本级别”一节。这些差异将在本节中描述。其中一些CPU上的键被标记为ONRUN和OFFSP，而其他CPU上的则被标记为on和OFF。考虑到标记所有这些键的作用，如下所述：Flash Memory Proction：可以使用此标准的硬功能，以防止无钥匙的无权限人员更改Flash Memory。当钥匙开关处于ON（接通）位置时，无法写入闪存。无论接下来的两个可配置特性是如何设置的，这个keyswit特性将始终有效。
The amount of memory ailab for a user program depends on how mu is configured for word memory. Configurab Memory has limid support in Logicsr Version . and lar limid K R words K AI words and K AQ words and full support in Control Version . and lar VersaPro all versions and CIMPLICITY ine Edition Logic Developer all versions. Q apr CPUs Additiol Serial Ports CPU CPU CPU Although all CPUs have a serial port that is accessed through the on the power supply the CPU CPU and CPU ea have two additiol serial ports. The s for these additiol serial ports are mound on the front of ea CPU. These two builtin serial ports elimi the need for the CPU access serial ports across the backplane resulting in betr sysm perfornce. These two ports support the SNPSNPX sr and slave procols see Breakfree SNP Procol on page . RTU slave procol in Firmware Version . and lar and the Serial feature in Firmware Version . and lar that ts you crea a cusm serial . Instructions on how use these ports can be found in the Serial C or lar. FloatingPoint th All CPUs can work with inger numbers. The set of inger numbers consists of all positive and negative who numbers including zero. The floatingpoint th feature ebs a CPU work with decil numbers in addition inger numbers. It also provides trigometric logarithmic exponential and radian conversion functions. Floatingpoint th is also referred as real number th. The CPU and CPU have always had hardwarebased floatingpoint th capabilities due the builtin th coprocessor ip. Starting with CPU firmware rease . all of the other CPUs in the CPU group were provided with firmwarebased floatingpoint th capability. Although there is a speed difference between the hardwarebased floatingpoint th of the CPU and CPU and the firmwarebased type this will t be significant ny users. For applications where fasr perfornce is important the CPU and CPU are the best oice. The floatingpoint th instructions are explained in the CPU Instruction Set Reference K or lar. Flash Memory All of the CPUs have builtin Flash memory whi serves two purposes: It provides nvolati srage of the CPU firmware. It gives you the option of sring program configuration and regisr data in nvolati Flash memory. Two ways of using this memory are: sre an onboard backup copy of user memory although we still remend that you keep a separa backup copy of your p program folder and for running in a batryss seme. For details pase see apr . Keyswit All CPUs have a keyswit; however some versions of the CPU firmware do t support all of the keyswit features see the section Dermining CPU Revision vels earlier in this apr. These differences are described in this section. that the keyswis on some of these CPUs are labed ONRUN and OFFSP and on others are just labed ON and OFF. Regardss of the labeling all of these keyswis work as described below: Flash Memory Proction: This standard hardd feature can be used prevent Flash memory from being anged by uuthorized peop peop without a key. When the key swit is in the ON position Flash memory cant be anged writn . This keyswit feature will always be in effect regardss of how the next two configurab features are set.
