Freelance - Profibus devices on same page in logic stop

Hello folks,

I have a Freelance SV9.2 that when I do a modification in the logic and a download, all Profibus devices on the same page stop then, I need to start motors again. Due to this situation every download must be in scheduled shutdonws however it's not the best condition.

PS.: before modifications all start signals are Corrected to "Running" but after download they go back to "Stop".

Any tips?

Best regads,

Hello Marco,

I guess with Profibus devices on the same page you mean I/O variables from a Profibus device that is used in the logic on that page?

And with Page you mean Program?

If you change the logic of a program and download it with load changed objects then this program gets initialized. That means the variables assume the initial values.

When you say you Correct the signals to running I guess you are changing the current values but not the initial values. You can see the initial values in the Variable list.

Try to set the initial values so that the motors will start, but be aware that this will also happen if you do a Load Whole Station or a cold-start for other reasons (like power fail for longer than warmstart is configured)
