三线制变送器如图三所示，所谓三线制即是电源正端用一根线，信号输出正端用一根线，电源负端和信号负端共用一根线。其供电大多为24V.DC，输出信号有4-20mA.DC，负载电阻为250Ω或许0-10mA.DC，负载电阻为0-1.5KΩ；有的还有mA和mV信号，但负载电阻或输入电阻，因输出电路方式不一样而数值有所不一样。以上三个图中，输入接纳外表的是电流信号，如将电阻RL并联接入时，则接纳的即是电压信号了。
Purpose: the self-supporting non-filled cable is suitable for the urban and township telecommunication lines of local telecommunication network, and also for the special network lines connecting to the public network. It is economical and practical to use the same outer protective layer for hoisting line and cable. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter is 0. 4, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 mm. Insulating material: high density polyethylene or ethylene-propylene copolymer. The color of the insulated wire is in accordance with the full chromatographic standard. Pair of insulated wires: two different colored insulated wires are twisted in pairs according to different pitch and are identified by a specified chromatographic combination. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Core tape: wrap with a polygrease film tape. Shielding: the two sides are overlapped with or without corrugated metal strip, beyond the cable core of the longitudinal capsule. The plastic film coated on the surface of the shielding belt and the bonding sheath of the protective layer: black low density polyethylene. Hoisting line: the hoisting line is 7 strands of galvanized steel strand, nominal outside diameter is 6. 3 and 4 mm. The tensile strength of two types of 75mm is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic paint to prevent the steel wire from corrosion.

一切正常之后，对于相对复杂些的模块，**先画出这一块内部的流程图。离线仿真应用软件编写好之后，或其中一个独立模块编写好之后，首先应进行语法检查，然后进行指令集与梯形图对应关系检查。艾特贸易小编曾经发现过指令集检查无误，但是与之对应的梯形图却不正常的情况。此时若将程序下载到PLC中，可能会出现错误，拒绝运行。以上步骤正确完成之后，接着才可利用仿真平台进行虚拟运行(PC模仿PLC进行工作，外部的输入和输出可以假设)。
