Simply sharing what works for me - take it or leave it

Thanks for your feedback. If you want to know how the program was made from scratch, please go and check out my courses in the description.

The premium course uses the same telegram as the video. Why would you want to use a free telegram?

Thanks. The graphics can be downloaded when you purchase my HMI course.

Awesome, thank you!

@@PLCskilltree I've signed up for full premium tutorial. I might be asking a few questions 🤔😁

Have you bought the premium bundle on my website? I did not get a sale from you so far (unless it’s under a different name)

@@PLCskilltree different name, Bucknorris74.

@@Ronin_Martial_Arts perfect, any questions before, during or after the course, send them In the course itself or to hans@plcskilltree.com

Hi Chris, My video about creating the software is the first step, before the commissioning. Then during commissioning you will need to setup the VFD - give it an IP address, configuring the motor data like voltage, current, rpm, power etc.... I typically get the motor data from the data plate on the motor (picture with mobil phone) and I use the setup on the BOP screen of the VFD to set the applicable parameters to the correct values. I also write down the motor data for each motor in my project worksheet, just so I have a backup.

1- I apologize for skipping ahead of the video i'am just a bit excited😋 2- It seems that my Noob brain and its short term memory had a misunderstanding. I thought that "VFD control FB + commissioning" was enough and forgot about adjusting the VFD's Parameters through it's BOP/AOP so it can be controlled by the PLC through PN like in our example.

Hi Chris, Thanks for your nice words, happy to hear you get something out of these videos. If you do not do the byte swapping, then your VFD control will not work (because your bits 0 to 7 will be switched with 8 to 15). Was that your questions?

@@PLCskilltree Yes sir you've answered my question

Hi Chris, Thanks for your feedback, love it! 1- "iLevel" and "xLowLevel" are part of the module data structure. And yes they are copied over from real inputs. There are a couple advantages to this. First off, it makes troubleshooting easier because all relevant data is easily accessible in the data structure. If you go online and open the DB where the module structure is situated, you get a great overview of what is happening in that module. Secondly, some inputs are being manipulated or scaled before they can be used (like e.g. scaling of a 0 to 100 degrees temperature sensor input). So instead of scaling this input every time that you use it, you scale it only once and add it to your module data structure. Now if you want to use it in another location in your PLC application, you can take the value directly from your module data structure (which is already scaled) instead of taking the input again. 2- Explanation is above 3- In case of simply moving the input, then yes a MOVE instruction will suffice. If you need to scale the input, then you might need a CALCULATE instruction, or even a small FC that takes care of the scaling calculations. I would recommend using an input (or an output) only 1 place in your user application. That input or output typically belongs to a specific module. So add it to that module's data structure. Furthermore, inputs and outputs should never be used directly in re-usable function blocks, always assign them to the Input or Output of the block interface. Else your function block is dependent on those exact inputs or outputs and cannot easily be copied to other projects or cannot be called multiple times in your application if needed. I hope this helps clarify things. -Hans

There’s a complete lecture in my HMI course dedicated to system diagnostics. I’m only using OB1 in my courses but I might update my premium content with interrupt OBs.

I disagree about it being complex. It’s actually straightforward with simple steps. If you’re used to building structures for your plc applications then this example is relatively easy. Can you send me a link to the library that you are mentioning?

Thanks. You will learn how to build structured TIA PLC and HMI applications from scratch, not just loose concepts or isolated examples - complete and fully functional applications. If you go to my website www.plcskilltree.com, you can read much more about each course or bundle and there are plenty of testimonials from people who took my courses. That should give you a good idea.

You select a graphic for the “off” state (=when not pressed) and another graphic for the “on” state (=when pressed). So basically 2 images.

Thanks for your feedback!!

The complete code is available as a download in the full course which much more information.

The integer is used as the state representation as a number. It’s used for defining the conditions for switching from one state to another. The boolean states are status flags for the actual states. You would use those booleans in other parts of your logic. Hope this clears it up.

I think that’s maybe a bit much to ask from a PLC simulator no? 😃 S7-PLCSIM allows you to simulate both PLC and HMI super easy with a click of a button, even simulating servo drives. I just used it to run several servo axes in positioning tasks using only my laptop.

@@PLCskilltree apparently not, if the Control Expert simulator manages to deliver this feature. The CE simulator has other weaknesses like wrong memory mapping sometimes but that's another story

@@simxschl I have experience with Rockwell and Siemens simulators and the TIA S7-PLCSIM is by far the easiest to use with most features. I do not have experience with Schneider simulators so you could be right, it might be better. But it doesn’t help you with simulating TIA Portal applications , which is what I am interested in 😃

@@PLCskilltree true that...

Which drive did you add? Which plc are you using?

Using the InOut of an FB only passes the UDT through to the FB, like a gateway (=call-by-reference). Using the Input and Output of an FB required copying to and from the instance data of the FB = requires extra resources. I only use FCs for small repetitive tasks that don’t require static memory, like small calculations, conversions, or scaling operations. I use practically only FBs in my projects (and they get very big) and I never had problems with work memory (retained memory is a different conversation)

Not sure what your question is, please be more specific

@@PLCskilltree I have 2 seperate projects. One has only the PLC and the other has only the HMI. Now I want them to be in the same project so I just copy the HMI from the HMI-Project to my PLC with drag and drop. After that I set the PN/IE connection for them and try to simulate the programm. THe Problem is that on my screen I only see for example #### instead of the value that I drag and drop from a data block. So I-m trying to solve that problem. Maybe you could help me ?

@@elnino9139try and check your PG/PC interface (start typing “PG” in the start menu of your Windows). Make sure it’s configured with the correct network adapter. In case you’re running a simulation on your laptop, it should be set to PLCSIM. In case you are downloading to a hardware PLC and run a simulated HMI on your laptop, it should be configured with the network adapter that you use for downloading to your hardware PLC. The hashtags indicate that there is no connection between your HMI and PLC. Check as well if “Connections” is set up correctly in your HMI application.

@@PLCskilltree Thanks for the helping. I have figured it out. The problem was that I chose in the loading plc menu X1 instead of PN/PE_1. And then it forced me to type some password for PLC and I forgot. Thats a bit rough but I think I will copy the Data seperately to my new plc in another project. Hope it will work as well

S7-300 PLCs do not support optimized block access. This video is made for S7-1200/1500 controllers.

How is it different? Would be nice to know 👍🏻

Profibus is kind of an outdated technology, I prefer to create videos on newer technologies

@@PLCskilltree ok but in India most place we are used sir

@@amarnathnsw9392 I understand

Thanks for your explanation Alex, I almost use the exact same tag name convention as yourself 😃. As for merkers, you are correct, they should be avoided at all costs. Build structured data in Datablocks instead.

Thanks, sorry no experience with ATV0320

Try and check out this video: th-cam.com/video/NwYUzVlbihE/w-d-xo.htmlsi=of4zcl3UmDzf0J7_ This is the complete chapter of my course. If it’s not in there, you’ll find it in the course itself (info on the course in the description below the video)

As far as I know, svg images are converted to a rasterized image in Runtime (for comfort panels anyway). You can export as svg if you prefer that. Not sure about the filesize, transparency possibilities etc… I am used to png images due to the small filesize and transparency features. Good remark, thanks!

Never mind, I didn't see the option that said "Show all", now I am able to see it, thanks anyway!

Troubleshooting is the best way to learn, well done 😃

Glad you enjoyed it!

The complete application is available in my premium bundle. Check out the description below this video for more info 👍🏻

Buy the course 😃

You’ll have to set bit 11 “setpoint inversion” of the controlword to “1”. My course (check the description below the video) comes with a sample application that shows you the exact logic first controlling the drive (including running the drive in the opposite direction)

My course (see description below the video) contains the complete application with lots of networks with logic 😃
