[Xinge education] poor learning host computer series -- building step 7 Simulation Environment

Students often ask me , Learn whether to buy the upper computer PLC hardware ？

My general answer is ： Rich people buy by themselves , Poor build simulation .

PLC hardware , For learning the upper computer , It's the icing on the cake , Economic conditions allow , It's better to have one , Conditions do not permit , We can also learn by building a simulation environment , So I've prepared a series —— Poor learning host computer series .

 

01、 Write it at the front

 

 

  The theme of this paper is based on STEP7 Build Siemens simulation environment ,STEP7 It's Siemens 300 series 、400 Series of programming software , Early learning PLC My little partner must be familiar with this , Although it can be done in TIA Write in the environment S7-300/400 The program , But there is no denying that , There are still a lot of businesses （ Especially in manufacturing ） In the use of S7-300/400 PLC, If you only use S7-300/400, I think STEP7 Compared to boto , It will be smaller and more convenient .
Software environment ：SIMATIC Manager V5.6、PLCSIM V5.4、NetToPLCsim、CMSPro Hardware environment ：WIN10 64 position

Software gets keywords ：STEP7、PLCSIM、NetToPLCsim、CMSPro【dotNet Industrial control upper computer ：thinger_swj】

 

02、 Simulation steps

 

1、 Create a project ： Use STEP7 Build a PLC Project , The name thinger_cn_PLCSimulator, Insert a SIMATIC 300 Site , As shown below ：

 

 

2、 Hardware configuration ： Turn on hardware configuration , First insert a rack Rack, And then insert a S7-300 Of CPU, It's better to choose the belt directly PN Interface , The choice here is CPU 315-2 PN/DP, As shown below ：

 

 3、 establish Ethernet： Double click PN-IO, In the pop-up window , Select Properties >> newly build , Then the IP Change the address to 192.168.1.123, Here IP The address is set by yourself , As long as it is in the same network segment as the local computer .

 

 

4、 Compile and store ： Click on the red box in the figure below , Compile and store the hardware configuration . Piece simulation 300/400PLC, You don't need to install a huge botu Software , And the main use here is NetToPLCsim The plan , It doesn't need to be installed PLCSIM-Advanced.

 

 5、 Start NetToPLCsim： Execute with administrator permission NetToPLCsim, The following window will pop up , Choose yes .

 

 6、 Start PLCSIM： stay SIMATIC Manager In the form , Click on the red box in the figure below , Start PLCSIM, If the diagram is gray , Explain PLCSIM Not installed .

 

 7、 Download PLC The program ： stay SIMATIC Manager In the form , Click on the red box in the figure below , Download PLC The program .

 

 8、 newly added Station： go back to NetToPLCsim In software , Click on Add, newly added Station, As shown in the figure below ：

 

 

9、Start Server： stay NetToPLCsim In software , Click on Start Server, As shown in the figure below ：

 

 

10、 Communication test ： After following the steps above , One S7-300PLC The simulation environment is set up , Then you can communicate , The communication test platform is used here , Set IP Address: 192.168.1.103,PLC Type selection 300PLC, Read variable selection MD0（ Because I didn't write any program , It's not established either DB Block , So we test it directly M Storage variables ）, Type selection INT Type , Read and write data , Test , The results are as follows ：【dotNet Industrial control upper computer ：thinger_swj】

Pay special attention to ： Here IP The address should be filled in PC Of IP Address , instead of PLC Of IP Address .

 

 

03、 Overall summary

 

STEP7 The biggest advantage of simulation is that it can be used SIMATIC Manager Software simulation 300/400PLC, You don't need to install a huge botu Software , And the main use here is NetToPLCsim The plan , It doesn't need to be installed PLCSIM-Advanced.
