CI854AK01模块备件参数说明

绘制各种电路的目的，是把系统的输入输出所设计的地址和名称联系起来。这是很关键的一步。在绘制 PLC 的输入电路时，不仅要考虑到信号的连接点是否与命名一致，还要考虑到输入端的电压和电流是否合适，也要考虑到在特殊条件下运行的可靠性与稳定条件等问题。特别要考虑到能否把高压引导到 PLC 的输入端，把高压引入 PLC 输入端，会对 PLC 造成比较大的伤害。在绘制 PLC 的输出电路时，不仅要考虑到输出信号的连接点是否与命名一致，还要考虑到 PLC 输出模块的带负载能力和耐电压能力。此外，还要考虑到电源的输出功率和极性问题。在整个电路的绘制中，还要考虑设计的原则努力提高其稳定性和可靠性。虽然用 PLC 进行控制方便、灵活。但是在电路的设计上仍然需要谨慎、全面。因此，在绘制电路图时要考虑周全，何处该装按钮，何处该装开关，都要一丝不苟。
4) 编制 PLC 程序并进行模拟调试
在绘制完电路图之后，就可以着手编制 PLC 程序了。当然可以用上述方法编程。在编程时，除了要注意程序要正确、可靠之外，还要考虑程序要简捷、省时、便于阅读、便于修改。编好一个程序块要进行模拟实验，这样便于查找问题，便于及时修改，好不要整个程序完成后一起算总帐。The purpose of drawing various circuits is to connect the address and name designed by the input and output of the system. This is a crucial step. When drawing the input circuit of PLC, we should not only consider whether the connection point of the signal is consistent with the name, but also consider whether the voltage and current at the input end are appropriate, and also consider the reliability and stability conditions under special conditions. In particular, it is necessary to consider whether the high voltage can be led to the input end of the PLC. If the high voltage is led to the input end of the PLC, it will cause great damage to the PLC. When drawing the output circuit of PLC, we should not only consider whether the connection point of output signal is consistent with the name, but also consider the load capacity and voltage resistance of PLC output module. In addition, the output power and polarity of the power supply should be considered. In the drawing of the whole circuit, we should also consider the design principles and strive to improve its stability and reliability. Although it is convenient and flexible to control with PLC. But the circuit design still needs to be cautious and comprehensive. Therefore, when drawing the circuit diagram, we should consider carefully where to install the button and where to install the switch.
4) Compile PLC program and conduct simulation debugging
After drawing the circuit diagram, you can start to compile the PLC program. Of course, you can program in the above way. When programming, in addition to paying attention to the correctness and reliability of the program, we should also consider that the program should be simple, time-saving, easy to read and easy to modify. A simulation experiment should be carried out to compile a program block, which is convenient for finding problems and modifying in time. It is best not to calculate the general ledger together after the completion of the whole program.
