20708 error when running in plc, but running fine in ARSim

Hello,

I am trying to run a program for deltarobot configuration. When i run the program in ARsim in mappcockpit it is running fine without any error. But when i connect with my plc and run the program it is giving 20708 error. I am attaching the screenshot for your reference. I turned on Automatic transfer of userfiles in CPU configuration, created file devices also but still i am getting the error when running only with PLC. In Arsim mode it is able to find the program file and run it. I am attaching the screenshots of my configurations for reference. Kindly provide a solution. Thanks in advance.

Depending on the AR version you’re using the C partition of the PLC is blocked.

You should use F:\ instead.

Hello,

I am using AS 4.12.6.106 version….i used F:\ instead, but i am still getting the same error.

Hello,

20708 means the file you are looking is not there, so even if you have created the file device. If the file is not there, this error can appear. have you placed the file in the corresponding file device in the plc?, if you have ftp activated, you can just just filezilla to place the file inside.

Hello,

I tried filezilla, but i am getting error 530 authorisation failed, i am entering the username and password set in the configuration tab of my plc..but still cant connect it. I am attaching the screenshot of my configurations for reference. Is there any other setting should i enable? i am sorry this is the first time i am using FTP transfers..i was initially trying with Devlink programs to transfer files. But that didnt work either.

Thanks in advance

yes, on the shared device choose “all devices“

This is purely guesswork, but since you censored the “password” field: did you enter whatever was in that field or the actual password? Because what you can see in AS is the hashed password, not the actual one.

E.g.:


I enter “MyPass” here and it is shown… until i press enter:

The password to use in my ftp client will still be “MyPass”

Hello,

Thank you for the solution, i changed it to ‘All devices’, created a folder and added the program. Now the 20708 error is gone.
