hello

at first i apologize for the lack  of my english language.I have questions about the training file that is available on the site of the simens.I have attached this pdf and tia portal file for you.

1-can we use the program that the pdf says  for each project?(when we need to control)

2-if we can،how can we change the set point in this program?

 Dear  moghimian.s ,

I think using the demo project provided is good only once for learning and testing.Your project may differ in type and you may use different scenario customized for your project to develop that.Using extensive and superfluous simulation blocks are not necessary in real application plus you need major modifications in screens of  HMI .

In brief, this demo like others are provided to give you idea.It is your duty to customize.

I hope this helps,

...so can we have a program that includes  just a pid_compact block?  even without proc_c block???

Yes  Of course , Most of PID in real industrial applications are like that

excuse me.. i need an example for just pid and proc_c blocks because i want simulate the analog  input and output.this program does not work:(((

 Do you use the real S7-1200 or only S7-PLCSIM V13 ? What is the exact version of program you are using?

real plc s71200 cpu 1212c dc/dc/dc and software:tia portal v13 

i dont want to use any external equipment  for produce analog signals i want to use proc_c

 So if it is a real CPU, your program should word.The first suspicious point to check is COM_RST signal.Create a watch table , list all important signals of both function, and check the online.Also provide a snapshot here for further investigations.
