Hi,

I'm preparing function (PLC side) for ABB painting robot to clear robots cache memory.
After some number of 'models' send to the robot there is some kind of memory overflow.
We want to avoid that problem by periodical memory reset.
I was advised to use two particular robot inputs sdiStartMain and sdiStart.

Anyone has any experience with such problems?
Any hints how to deal with this?

 

Best Regards!

If all else fails, read the manual.

LoadStart will load/reload a program from disk. I am not positive but would assume that this action would clear the program cache. It is quite noticeably slower than Start and StartMain of a pre-loaded module.

OK,

let me clarify - I'm looking on this problem from the PLC side. I have my interlock over Profibus DP and I want this procedure to be executed automatically based on logical conditions in PLC.

I have some description of painting robot I/O called 'PA Services User's Guide'. Based on this documentation all communication between PLC and robot is realised.

The question is how to use interlock signals to perform robot Cache reset with as limited timestamp as possible.
