Thanks Team Codesys, 
With your guidance I am able to connect with Codesys device.
Please guide me to connect Arduino Uno with codesys control Win V3 with serial port, I am trying to connect  but modbus slave bus is not getting run.
Do we need to prepare Arduino in Arduino IDE also ?
I tried all steps but i am unable to get output on the hardware pin.
If you can help to resolve this problem, 
I will really appreciate you.
Thanks

Good Morning Prof. Patel,

the User Authentication is an access to the controller which is mandatory since the latest CODESYS Version due to IT security reasons.

In case you forgot your password please do the following:

· Stop the SoftPLC with a right click on the icon in the task bar and click on “Stop PLC”

· You can reset the User Management configuration by removing the user management csv files. In order to do so please open the Windows Explorer (or any other file system) and the directory C:\ProgramData\CODESYS\CODESYSControlWinV3

· In case you find multiple directories with random numbers (e.g. 11392D7D, 597193B0 etc.) in this directory please select the latest updated directory and open it. Sort the directory by file name extension and select all files with the extensions .csv or .csv_

· Start the SoftPLC again with a right click on the icon in the task bar and click on “Start PLC”

· When you scan the SoftPLC and connect it for the first time after the reset you are asked to enter a new User authentication. Please enter an Account name and the according password and save these login credentials for the next access to the SoftPLC.

This should solve your problem.

Best regards

I would use the Gateway on the PI - to scan the plc. ( You have been asked on deploying the runtime if you want to install the EdgeGateway too9
Add new Gateway with the IP address of your PI and scan the plc that way.
