A customer asked me to make a program for a very old ABB robot with a S4 controller.
I started years ago programming with S4C+ and I would not like to do all the programming based on that S4C+ controller programming style to find that it can't work on a S4 robot.
After copying a couple of files to the robot controller everything worked except the calls to SYS modules functions... I think I had to write GLOBAL in front of whatever function or procedure I wanted to call from different modules, but I can't be sure without some documentation.
Do you have a manual for the S4 rapid programming?
If you don't have a manual or you can't share it, can you explain me how should I write the function declaration in a sys module to make it visible in the program module loaded?
Apart of that, a manual for the old "Robotstudio S4 Lite" would also be nice to have, I would like to create a virtual controller and send my programs there to get them checked by the robot compiler.
Thank you very much.
