Wanting to add "maintenance" mode push buttons in the i/f panel to open and close a gripper.
Gripper uses two external outputs. One to open and one to close..
The open program Douts universal output 1 on and Douts universal output 2 off.
The close program Douts universal output 2 off and Douts universal output 2 on.
(have broken group and each universal fires its external)
I hoped the solution would be as easy as adding a i/f button output in the ladder with an OR, but the universal latches the output.
Any ideas??
