Một kế hoạch không phải là một chiến lược. (A Plan Is Not a Strategy)

And if something that you say is in the logic that would have to be true for this to work is not working out quite the way you hoped, it'll allow you to tweak your strategy.
Và nếu điều gì đó bạn nói nằm trong logic mà phải đúng để điều này hoạt động nhưng không diễn ra như mong đợi, nó sẽ cho phép bạn điều chỉnh chiến lược của mình.
Go do it and watch and tweak as you go along.
Hãy làm đi, quan sát và điều chỉnh trong quá trình thực hiện.

Now you see this back calculation out what I was talking about so this back calculation out need to be connected to back calculation in okay so we have a connection from here to this guy to make it look better you can do like this okay so this out is connected here and this out is to in back calculation in to white your reset wind up and bumpless transfer concept which we actually talked about before so a very important thing now which we really need to understand is there are few things that you have to have here which are not actually there so how to get up something in a PID which never which is not existed even you can see there's no set point here so you have to click right show parameter browse first first of all you have to understand I want this parameter to appear at the input side of the PID block so I selected type as input get into the browse now you have to search for set point so this set point is right here just click okay and click okay now you would see the set point is there also right now let's edit there are few things that you have to actually take care when you are going to make a PID loop so that is control options so when you click on this here you can actually make reverse or direct acting by default when you haven't selected anything this is reverse acting but when you are trying to you know it as a direct acting then you can do it like this you understand the point so I click on direct acting and click okay now this guy is ready okay so good now we can give a set point some value where is the set point set point is here I want my PID to be at 89 and where is the set point is good good cascade okay then I want this guy to be at some value right I don't want this to be set point I need to give it some value here to simulate in also so I will enable it I would give it 80 value okay so this is now 80 value and this set point is termed as your how much was how much was the value for the set point 89 okay now if we give it a 10 value for instance this AI that would behave in a better way I think let me instead of getting a high value we can give it a same 60 50 value that's a better way now you can see there are many options that exist if you come here into this block you can also see there are many options but first of all we have to understand see the gain is there there is a PIND rate is there that is there and you have a reset and you have a gain also and you have a outscale that you have actually scaled a value that your output would be between 0 to 100 it would not exceed more than that I'm sure that my process value or my control wall is between 0 to 100 percent there is no more actually opening of the control wall more than 100 percent then in that case you can see you can put up a zero limit for a low limit and high limit would be adjusted to 100 you can see here right any questions it's okay this this is your high limit in similar way you can also give a low limit in high limit to input values also but yeah this is a set point and one important thing with more thing yeah you can see the mode option here it's in the manual you can put it auto you can put it manual here you can put it cascade you can get put cascade remote and remote output but we would be talking about auto and manual in this case so I put it in manual and I'm trying to give a value and I need to save this program I need to download it and then see what is the response upload to the download to the station you can first upload it select okay and it's going to upload and then download anyway okay so now you see you put up a value of 50 and your set point is 89 as 79 and you're trying to give the output value to some value let's see and I want to give this output some value so I'm trying to give out manually so I'm trying this to be 30 okay so I put this output manually 30 value now I'm going to change the mode of operation to automatic to see how it operate so I select mode and make it into auto and click so now we have to tweak with the PID terms to see the response so if you see that we have a gain here so I want my gain to be high so what I where is the gain best way is put here and just select some give some value and I give it one to see the response now see the value is changing when I give a gain gain value you see the value of feedback is also changing and that back calculation is getting back to here also you see that's what I was talking about the feedback is going to be fed in in the back calculation now system is trying to reach to that value this is a set point 89 and your value is 50 okay so the system is trying to maintain that value if you try giving a value for example 675 see the response is changing so based on what you have at the AI which is your input your output would regulate the flow so this output would be actually connected to control valve and this AI is connected to the temperature transmitter in the case what we were actually talking about that's all
