Dear all,
I have a new project using pickmaster3. There are 2 conveyors, for pick and place. In the pick conveyor, I must pick 2 items ( alternately) and place it at the same time in place conveyor.
THere are 2 suction cups that connected to the 2 cylinders pneumatics. So for the pick procedure should be move down the cylinder A, pick bottle 1 with suction cup A, move up the cylinder A, and then move down the cylinder B, pick bottle2 with suction cup B, move up the cylinder B , and the last step is place the bottle 1 & 2 together in the place conveyor.
For my basic knowledge, there are DO number 13-14 for suction & blow1, and 15-16 for suction & blow2, I don’t know how to send the signal to make cylinder A & B move up and move down. Can somebody share with me, how to edit RAPID code for this application?
THank you
BR,
Carmila

Hi,
Use general TriggIO/TriggEquip/TriggL to synchronize the right event with the sequence. Some of these are explained in the UserGuide.
