Hi, This freez problem I hade also somehow. I think it's a bug of software (Not sure) Have you installed the SP of PLC Sim. Probably your problem is solved with the SP because PLC Sim is totally new software and it takes time to solve all the problems.

where do ypu mean exactlly? After that you click start simulation? If yes, does the simulation start? Do you create a workspace and turn on the virtual plc?

@ sprry it was my mistake. I installed the PlCSIm and it asks for a computer Restart i did it later and I counldnt access offline simulation it’s working now

@@peterpeet5969 just select another folder for the installation path.

Hi, just like other simulation click "go online" in Tia or click on glass icon. It is like other simulations so I didn't do that again.

@@industrial_automation i did that it went online but i cant change the inputs from 1 to 0

from 1 to 0 ??? has the input a start value of 0? if yes then somewhere it's overwritten to 1. Do you see the CPU in run mode? It's really not easy to troubleshoot a plc problem just with coments.

@@industrial_automation from what people told me i can only change the bit from 1 to 0 is by using the force table is this right?

@@maherdaibes9344 With Force Table you can do it but as its name indicates the input will be forced and that's not a solution that you need. I checked it with a CPU 1516-3 PN/DP V3.0 and TIA Portal V18. I could change any input (Peripheral --> P and Q, Memory--> M and from a DB) all of them I could change 0 to 1 and again 1 to 0. Write which cpu are you using. for example some versions does not support Plc Sim advanced. Try to make a new project with the CPU that I've used. Probably your input is overwritten somewhere in your code.

@@carlosgallego1076 you're very welcome

Try your code with virtual plc that I've done in this video (Download your code to the virtual plc). It should give you exactly your time of windows. So you can find out if your code is correct or Time/date of your PLC is wrong.

Do you have the time in UTC and ms? Does the first block "SysTimeRtcHighResGet" work? Do you work with a real PLC or like in the Video with virtual PLC?

@@industrial_automation I have a similar problem, Im working with a real PLC and the time and date are wrong

@@industrial_automation My problem was solved. Thanks for your quick reply

@@industrial_automation Hello, l changed my laptop and once again same problem occurred. I am working real display unit. i have a time in UTC and Loc_ms and everything are working fine but time and date is not correct. i copied and paste the code from my previous laptop at where the code worked fine. I think the problem is laptop's system itself. How can l solve the issue? Thanks

ist it showing the time wrong or like the first case 1970-01-01? If the time is 1970-01-01 it means the variable has still its initial value and your code does not work. is the first function SysTimeRtcHighResGet incrementing?

Function and Function block you have also in TIA. See my last video of TIA playlist.

@@industrial_automation tnaks

@@mohammedrezk8072 you're very welcome

Right. At first it will be 1000 0000 but then it will be shifted because the bottles are also moved to to right on convoyer after each detecting of bottles and because of this I wrote the code in this way. For the last bottle to prevent this I'v used the bit StopShift (NC before EN of SHR function in Network 10) when the number of bottles is 8 so with last bottle the shift register won be changed.

With activation you mean to set its value to true? If yes, you can use watch table to modify the inputs. Beside that you can also use PLCSim to change the values. See my videos PLCSim and watch table in TIA playlist.

@@vatsalthaker2122 look at the Tia playlist. I've already made a video about it. th-cam.com/video/XvRjnn5FIFY/w-d-xo.htmlsi=TMP-WA1by3WKFVOZ

@@industrial_automation actually i am asking more examples....that tutorial was very good..I am working in beverages industry so here they told me that filling operation is done with help of shift registers that's why I am looking for more insight for how to use shift registers thanks for your reply

You're very welcome.

In PLCSIM V18 do you mean? Yes you can't find it because if you want to simulate 300 or 400 series old version of PLC SIM will open. I think V5.4 V18 is just for 1200, 1500 and ET200 CPUs. V5.x supports 300 and 400 series.

@@industrial_automation nah doesn't work for me i don't what s the probleme they show me a message that (((some information may have been lost. This should not have happened........)) and the Tia portal restarted

@@industrial_automation also when i want to charge the program i can't because there is no advice to connect with i don't know how to use the virtual one

​@@oumaimasahir753 Which version are you using? if 18, have you completely uninstall previous version befor installing this version? Have you updated some part of TIA? Maybe some incompatible versions of other parts you have installed. It can have many reasons.

@@industrial_automation now im using V18. But i have installed V17 where i did my project for the first time

Sure. These topics are for advanced level so we need a little bit time to complete all the basic videos.

@@industrial_automation Thank you

If you mean what I used in the video, it is installed when you want to install the codesys. Don't you have it?

You're welcome. For the program you can get an Idea from my video of Codesys for date and time. For visualization I will start the tutorial in few month.

In my opinion just focus on the language that you want and you need. I personlly prefer ST because if you have experience with other programming language like C or C++ it easier to learn ST.

@@industrial_automation i dont have experience

@@parshwabhavsar7855 Then you can start with ladder logic diagram.

Hi, No it should work with boot application because a copy of the application will be stored in the target device (PLC or any controller like Raspberry Pi). I tested this with a Festo PLC. What I've done: Create a project and the persistent variable like in my Video. Create a boot application. Change the values. Power on and off. (Even I closed the codesys and then restarted it). --> The values are retained.

@@industrial_automation thanks for replying! When you uploaded with a boot application, you didn't download the project to the PLC/Device before that? You only used the Boot Application to send the project across? I'm away on holiday at the moment, but when I'm back in front of my demo rigs, I'll try it with your method and see if it resolved the issue I have with persistence variables not retaining when using Boot Applications. Hopefully it does!

@@darrenewer I did the download. Even I changed some part of code and downloaded the changes. It works. (Be carefull just not to change the persistent variables. If you change them the values will be lost)

@@industrial_automation if you tried this by directly downloading the program into the device via ethernet, then that's masking the problem I'm talking about. Try a brand new program, brand new device with no program installed. Create a new codesys project with persistence variables, and then create a boot application. Add the program to your device via the boot application (not ethernet). You may find the problem I'm talking about with the presence channel files not being transferred across within the .app and .crc files.

@@industrial_automation yeah, this method doesn't work if you only use the Boot Application method to transfer your project across (i.e. laptop NOT connected to PLC). You'll notice within the PlcLogic folder that the ac_persistence folder is missing. It only transfers across when you perform a direct download (i.e. laptop connected to PLC).

You're very welcome.

for sure. After some video about Codesys we will have this topic.

​@@industrial_automationare you saying, you will start with codesys tutorials that includes such topics before working on Siemens tutorials?

@@Time4yes No. Next weeks we will have some videos about codesys, then we will have videos about FC, FB in TIA.

@@industrial_automation please add the videos waiting for a too much time as a genuine subscriber...
