Siemens PLC selection Siemens PLC is divided into three types according to small, medium and large, which are S7-20, S7-300 and S7-400 series in turn. In recent years, LOGO has been developed! Series, Siemens PLC selection is the same as the general PLC selection principle. 1. How many bits is the processor of 200PLC? The data length of the central processing chip of S7-200 CPU is 32 bits. It can also be seen from the data length of CPU accumulators AC0/AC1/AC2/AC3. 2. How to calculate the power demand of S7-200? S7-200 CPU module provides 5VDC and 24VDC power: When there is an expansion module, the CPU provides 5V power for it through I/O bus, and the sum of 5V power consumption of all expansion modules cannot exceed the power rating provided by the CPU. If it is not enough, it can't be connected to a 5V power supply. Each CPU has a 24VDC sensor power supply, which provides 24VDC for the local input point, 擴展模塊的輸入點和擴展模塊的繼電器線圈。如果電源需求超過CPU模塊的電源配額，您可以為擴展模塊添加外部24VDC電源。所謂功率計算，就是用CPU提供的功率容量減去各個模塊所需的功耗。
