TIA Portal: PID Compact - How to program and use it!

After some pre-work in the last videos, let's get our tank system running using a PID controller!

Contents:
- PID Compact
- Cyclic OB with 1ms cycle time
- Block parameterization
- Autoscale
- Block explanation on Inputs/Outputs
- Fitting the block to our tank system example
(- Troubleshooting)

This is great! Thanks so much for continuing with the phenomenal Siemens PLC videos. I have learned so much from you. Keep up the awesome content!

Thank you very much. by end of my headache day, I love to spend one hour on your informative videos releasing all the daily pressure. thank you Hegamurl

Thank you my friend, I've spent almost two days trying to configure the PID control without sucess. Now it's

Mate, you're such a good teacher. Thank you for all the uploads!

[kishorvalsalan]

You are the best instructor with regards to automation tools. They way you present is just

Siemens made really great product, and you made it more easier to use! I never thought PID can be this easy in Siemens PLC. I guess now my fan operation is really depend on my intermediate relay's life.

Thanks, teachers in my school put videos with your work 😂

That's a very good video!

However one thing I'd change is the cycle time of the OB31.
1ms is really fast, and if you're using a slow PLC or a lot of PIDs the PLC could need more than 1ms to run the OB, which would cause an error.
"Slow stuff" like this tank level and temperature can easily be controlled with a 100ms OB (this was kind of the "standart" with S7-300 and its OB35).

Also if you're not using peripheral access to the In/Outputs there's also nearly no improvement in calling the OB twice as often as your PLC cycle time (e.g. if your average cycle time is 10ms there's almost no point in setting the OB cycle lower then 5ms). (the PLC will only update the values of IW and QW once it starts/finishes the OB1)

Awesome videos fella, I've used a few now and they have been amazingly helpful. As people have said before you teach the subject really well. Thanks.!

[XaviAllueva]

Thank you Sir, I really like the way you explain and elaborate things in your videos

[pardeepgupta]

Great job. I am chasing you in all tutorials

[mustafardk]

Thank you very much! Awesome guides! Why didn`t I find your channel earlier...

[Davidstinton]

Thank you awesome break down of how to use a PID

[claudio]

Great explanation about pids. Thank you

[christian_t]

Thank you for the incredible explanation !

[beastim]

Kindly share the link of how did you create this program of tank I couldn't find it in your tutorials. Thankyou for your time, your videos are really helpful. Happy New year from Duomo di Milano.

[jiiggsj]

Cheers mate. Your videos are very informative. All the best and keep passing the knowledge.

[MisShooter]

Great work! I really enjoy your video's.

The same thing happened to you, the difference is that I was in the start-up with maximum pressure, I think this is part of the Siemens developers who must improve the software.

[bazezikov]

your videos are god sent vielen danke bro
