error code 5

[darja]

In our measurement software we get error code 5 after about 3 hours running the program.

Does anyone know the problem?

thx

Hi darja,

maybe there is a file already open?

Do you use proper error checking in your app? Where does the error happen? When does it happen? What is your app doing?

😉 no file is open. i profed that.

the app is controlling different measurement devices.

i have a loop every loop step reads out a config file. in one loop step different sequences are passed.

but the error is random. the program is running some hours then the error occurs. i tell him to continue. thene it takes another hour when the next error occurs.

one loop step taks about 30 sec.

in one of these sequence steps the error occurs. but there is no connection to any file. 

thanks

Hi darja,

which function is giving your the error 5? Where does the error occur?

Anyway:

When you can continue your program without problems, you can simply catch that error and handle it correctly (i.e. cancel it programmatically)!

the error occures when i connect to a gpib device.

but not every time.  i can connect to it 100 or 200 times, then the error occures.

i will implement the error handling and try to change the gpib device.

Hi darja,

do you have to "connect" to the GPIB device each loop iteration? Usually you only need to write commands and read responses from the device...

[darja]

sorry, i meant that. we write to the device...
