Eventually you can make a Ladder loop which cannot be stopped.
Power-off EX-RC1 unit,
Change DIP switches to ID=0.
This force EX-RC1 to STOP mode.
Check communication.
Load empty project, or project with counter.
Power-off EX-RC1 and change ID to any number, but not 0.
Power-on EX-RC1, enter ONLINE mode and check that EX-RC1 works.
Review your code to find possible problem.

Well done!
Good to know that problem solved.
In such cases we recommend to test other USB port, test other USB-to-Serial converter, even restart PC.

No, it is not possible.
All temperature measurements are in 0.2 C/F.
You can convert temperature to text and show whatewer you want.

1. Open Device Manager and write/out/remember what is a COM port number assigned to connected V570 PLC.
2. Disconnect USB-A/USB-B cable from PLC.
3. Close VisiLogic.
4. In Device Manager go to "Menu->View" and select "Show hidden devices".
5. Right-click on installed driver and select "Uninstall device". In my case it is COM 5.
6. After finishing uninstall, run VisiLogic as Administrator.
7. Open Communication Settings and change to last tab with USV icon.
8. Follow steps.
9. Connect USB-A/USB-B cable from PLC to PC.
Windows should install driver.
10. Check in Device Manager what COM port number Windows assigned to PLC.
*Port number should be between 1 and 16.
11. Use this COM port number for PC-PLC communication.
12. Communication settings should be as follows:

What dificulty do you have>
Be more specific, then answer will be fastest.
1. What Windows Version do you use?
2.What is a PC/Laptop model?
3. Is there SSD installed at PC/Laptop?
4. Did you unblock UniLogic installation file before running it?
5. Does your PC account has an adminictrative rights?
6. What happen when you run UniLogic installation?
7. Other details.

@ravindkumar, last post posted more than 3 years ago. Isn't it?
there are a new VisiLogik already released, and a new Windows problems arised

Unitronics supporting 32-bits floatting format as mostly used.
Can you provide more information about your case:
- Device model you use with 16-bit memory float registers and programming documents, or link to documentation..
- Programming documents to better understand used memory float forma, or link to documentation.

It is useless to use very high frequency for PWM.
As you process is slow - it is recommended to evaluate UniLogic example \PWM\UniStream_070_PWM.ulpr
*You have to download UniLogic Examples.
In your case 0.1% for PWM should be equivalent to 2-3 scan times.
Instead of 0.1% precision you can use 0.5%-1.0% precision.
To do this, you have to linearize 0-100 range to 0-1000 range.

1. If not stated PWM or other special output type - this parameter refers normal output.
2. Switching time is exactly as stated in Data Sheet:
This means that after receiving ON or OFF signal from PLC, required state will be set after maximum 80 us.
2. It is useless refering to frequensy, as output signal should do something.
As output is managed by PLC, ON/OFF time will be dependent of scan time and other parameters.
Scan time will wary from ~1 ms to 10s ms, dependent of project complexity.
3. It is better to start by analysing project requirements.
Then check if modules fit project requirements.
4. Some modules has set of scenarios, involwing Inputs, Outputa, Timers, and some simple logic.
5. US series PLCs (T42) has special Interrupt routine with fixed interrupt time.
Hope this information helps to clarify I/O timing.

There are number of separate entities:
1. Jazz - has no support for SD card.
But has special Memory Module for cloning.
2. M90.Have no SD suport and no Clone option.
3. SAMBA does not supporting SD Card and cannot be cloned.
4. Vision PLCs can be cloned by use of SD card, but SD password should be set in ladder (to protect intellectual rights) and you should know this password (as Flex727 recommended).
All PLCs can store in flash memory Ladder code of projects, but programmer may disable this option.

@Ausman and all,
Google Play Store did chges in requirements for software.
Our R&D working to fix this.
Testing changes will take some time.

Hi.
There is a document at web site - "Version Changes & Bug Reports":
https://downloads.unitronicsplc.com/Sites/plc/Unilogic/UniLogic_1.33.236_November_2022.pdf
Following is printout from my Desktop computer:
C:\WINDOWS\system32>sqllocaldb versions
Microsoft SQL Server 2012 (11.0.7507.2)
Microsoft SQL Server 2019 (15.0.2000.5)C:\WINDOWS\system32>sqllocaldb info
MSSQLLocalDB
UNILOGIC
v11.0As you can see, I have installed 2 versions of MS SQL Server - 2012 and 2019. as I use multiple versions of UniLogic.
But UNILOGIC database always is in version v11.0 for compatibility.
Microsoft SQL Server Local DB 2012 used for all UniLogic versions before 1.33.xxx version.Starting 1.33.xxx version UniLogic installation install Microsoft SQL Server 2019 (15.0.2000.5)

Forward your request to support@unitronics.com

1. Send your request to support@unitronics.com
2. There is no automatic scaling when change display size.
You have to make required changes by yourself

Does not matter. It will be deleted.
By the way, I am not seeng this option at my desk with the same VisiLogic version.

We prove that this happens at our computers as well.
R&D will correct this.
Until correction will be applied - please use RickL work-around, and do not close this window.
For us is VERY important to simulate problem.
Ther we can introduce problem to R&D and require correction.
Fortunately, RickL recovered his operation sequence before crash happens.
This halps us to make software more frendly.
So, if you can simulate sequence of operations tor other crashes or problems - explain us how to simulate and we will require from R&D to fix problem.

Probably I will surprize you by answer - 32-bit PLCs are not a right instrument to "to do about 500 to 1000 cycles to calculate the model" when yse 32-bit Float Point representation.
Precision will be lost.
You need a DSP for this.
Now you have to decide how to continue.
PLC can be used to manage machine, but you have to use other device for "to do about 500 to 1000 cycles to calculate the model".
May be other Forum members have some ideas.

Regarding Unitronics Software Activation - after Microsoft updates at Registration Server Security Requirements changed.
VisiLogic 9.8.95 and up already updated to fit these changes.
Other VisiLogic versions require offline registration.
You can check if Online refistration is possible by next "work-around":
- In VisiLogic open "Help->Check for Update->Operation System".
If this test does not return error - online registration is possible.
Best regards,

Please send all information you provided in this post to support@unitronics.com.
Do not refer to this post - send all information you posted here.

Do not panic.
This forum is managed by forum members - volonters, and answers to your questions may be delayed.
For fastest help you should contact Unitronics Support - support@unitronics.com
I suppose that there is a File System error at your PC.
-
Please check if any Windows updates applied.
Windows updates may change security settings and limit access to folders, previously has no limit.
-
When write to Unitronics Support, please add following information:
1. Is your PC new from the store?
2. What is a Windows OS version?
3. Did you upgraded Windows OS last time?
4. Is this a new UniLogic installation or existing one?
5. Does this problem happens after Windows update?
Best regards,

I'm having trouble trying to register VisiLogic, I keep getting an error something about proxy settings.
Hi,
VisiLogic is a registered product name.
Please change your NickName to other one.

Did you tested these FBs?
there are a new VisiLogik already released, and a new Windows problems arised 
Jazz ModBus TCP\IP to Festo COMM-ST
in Jazz, M91 PLCs and U90Ladder

@Amit
Are you sure you selected right PLC?
Jazz has only 1 communication channel and in your case this make not possible online view and debug.
