Self-supporting full-plastic cable (HYAC) : self-supporting full-plastic cable has two kinds of concentric structure and calabash structure. The commonly used HYAC full-plastic cable is calabash structure. Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.

plc模拟量输入输出都会涉及到数据类型的互转问题,然而西门子300系统对于数据格式有着明确的规定,一般的四则运算都是在同一数据类型下才能进行的,这也是一直以来困扰初学者的一个问题。西门子300编程软件step7和博图都提供了相应的模拟量输入输出处理模块FC105,FC106。但是好多场合下,要对数据进行线性转换或运算,靠这两个函数是远远不够的。这时候就需要用户自己动手写一些数据转换的子程序。所以知道西门子数据类型转换是很有必要的。
