Hi everyone
sorry for my bad english, i'll try to explain you as best as i can...
I have an RJ controller and i would like to put a 2 color stack light in the cell.
I have i/o unit but it doesn't seem to have any process I/O board i could use for that purpose.
I would like to have a light active when the robot is in operation and another when the robot is in fault. I was thinking about using the fault led and operation led on the panel of the controller but there isn't enough amp to activate a relay.
You guys have any suggestion on the best way to do that? Is this something i could do with Karel and activate an output?
Also, i would like to know what i should use to be safety 4cat. This controller doesn't have DCS and i don't know what is usually use instead. Do you usually put contactors in the circuit that power the drive?
Thank you.
