PLC Programming Tutorial for Beginners_ Part-2
• PLC Programming Tutori...
==========================
In this lesson we will learn how to write a PLC program using an "S7 300” PLC and “STEP 7” software.
We have two pumps which are being used to transfer two separate liquids into this tank.Inside the tank there are two level switches installed in the lower and upper parts of the tank respectively.
There is also an electrically powered mixer inside the tank which starts working for a defined period of time, mixing the two liquids together after the tank has filled.
We also have a discharge valve in the bottom of the tank which controls the draining of the liquid from the tank.
When the level of the liquid drops to the level of the switch's position the contact closes, sending a 24 volt DC signal to the PLC input.
We want to write the program so that when the level of the liquid reaches this minimum, the pumps will be activated and begin filling the tank with the liquids.
The pumps continue filling the tank until the level reaches its maximum at the higher level switch. When this happens the open contacts in the switch will be closed and another 24-volt signal will be sent to the PLC input telling us that the tank is full.
When this signal has been sent, first the pumps should shut down so that no more liquid enters the tank, and then this mixer should be turned on.
We want the mixer to operate for seven seconds, mixing the liquids that have been pumped into the tank.
After seven seconds the mixer should automatically shut down and this discharge valve should open.
With the valve open the liquid will be discharged from the tank and transferred to another location within the factory to be processed.
When the level of the liquid in the tank drops to the minimum set level of the lower switch, the switch contacts will close again thus starting a repeat of the cycle!

[@ronnieperez8519]

I remember getting a taste of this stuff when the processing room I used to work in was getting retooled and programmers were working to get all valves, mixers, sensors etc. operating correctly. I as a lowly operator got to see that. Never knew how much went into programming something simple as turning a mixer on or off.

[@gawadhassan8524]

Excellent clear explanation

[@BiMiHi]

+RealPars could you explain how are you chosing hardware that you are using? Are those elements you work with in real work? Are they somehow better then others?

[@realpars]

Hi there, Sorry it seems like we have not been notified for this comment. I know it's too late and you've have probably found the answer to your question but I'm answering this hoping it can be helpful to others. The PLC hardware that we use depends on the specifications of each project. For instance, when you have 12 digital input signals, you need to select a digital input card that has at least 12 inputs. In this case you can select a 16-point digital input card and use the additional 4 inputs as reserves in the case you needed to connect additional digital input to the PLC in the future. So the type and number of signals that you have in each project determines what PLC modules you need to use. The PLC hardware that we use in the software are exactly the same as the hardware we use in the electrical enclosure (the real world environment). I hope this help. Let us know if you have more questions.

Don't forget the low level switch! And there should also be an emergency halt/shutdown routine in case both contacts are open.

[@chrisdaughters]

My Senior Design group is trying to create a very similar application to this. The video was very helpful in determining what we need for PLC inputs. Do you have any recommendations on actual sensors that would operate similar to your high and low level sensors? We have found different proximity sensors and weren't really sure what to go with. Whatever you had envisioned for this program would work perfectly for us.

[@realpars]

+Chris Daughters There are different brands for level switches you can choose from. We usually use "endress hauser" or "Rosemount" for our projects. Take a look at the following links: bit.ly/1lO6LUH bit.ly/1OPW9Ag

[@realpars]

The inputs are identified by bytes, with 8 bits per byte. A 16-point input card requires 2 bytes. The first 8 inputs are in Byte 0 and are inputs 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7. The second 8 inputs are in Byte 1 and are inputs 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7.
