Local cable USES manufacuring HYA, HYAT, HYAC, HYPAT, HYPA andHYA53 HYAT53, HYPA53 HYPAT53 type cable is designed for maintelephone switching area, relay telephone cable, manufacuring HYA,HYAT, HYPA and HYPAT is mainly used for pipe laying, also can beused for overhead, but need to disconnect; HYAC only applies tooverhead, no need for suspension lines or hooks; The HYA53, HYPA53,and HYPAT53 cables provide the mechanical strength and corrosionresistance of the cables. They can be laid in any way, which ismore suitable for direct burial in rock areas. The operatingtemperature is -30 ~60 degrees.
绝缘材料：高密度聚乙烯或聚丙烯，按照全色谱标准标明绝缘线的颜色。绝缘线对：把二根不同颜色的绝缘线按不同的节距扭绞成对，并采用规定的色谱组合以便识别线对。缆芯结构：以25对为基本单位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带绕扎，以便识别不同的单位。
TEMP(临时变量)为暂时保存在局部数据区中的变量。只有在执行该POU时，定义的临时变量才被使用，POU执行完后，不再使用临时变量的数值。在主程序或中断程序中，局部变量表只包含TEMP变量。子程序的局部变量表中还有三种变量：IN(输入变量)、OUT(输出变量)、IN_OUT(输入/输出变量)。在局部变量表中赋值时，只需指定声明局部变量的类型(TEMP、IN、IN_OUT或OUT)和数据类型（参见SIMATIC和IEC1131-3的数据类型），但不指定存储器地址，程序编辑器自动地在L存储区中为所有局部变量指定存储器位置。
3、产品型号规格及范围：产品型号规格范围使用场合MKVV,MKVVP,MKVVP20.5-10mm2,2-61芯适用于弱电控制系统或强电磁场干扰区MKVV22,MKVV200.5-10mm2,4-61芯MKVV32,MKVV300.5-10mm2,7-61芯MKVVR0.5-6mm2,2-61芯MK。
6．超过500Kbit/s的数据传输速率时应避免使用短截线段，应使用市场上现有的插头可使数据输入和输出电缆直接与插头连接，总线插头可在任何时候接通或断开而并不中断其它站的数据通信。“天联”牌2芯紫色电缆6XV1830 0EH10多次被消费者协会评为优质产品。

PLC的CPU单元对用户程序的周期性循环扫描，与PLC通讯处理器对各远程I/O单元的周期性扫描是异步进行的。PLC的CPU单元没有直接对远程I/O单元进行操纵，由于远程I/O缓冲区获得周期性刷新，PLC的CPU单元对远程I/O缓冲区的读写操纵，就相当于直接访问了远程I/O单元。这种通讯方式简单、方便，但要占用PLC的I/O区，只适用于少量数据的通讯。全局I/O通讯方式全局I/O通讯方式是一种串行共享存储区的通讯方式，它主要用于带有链接区的PLC之间的通讯。
