Hello. I have been trying to activate the EE pins of the robot using the RO registers, but I have not had success. I have already read the manuals and watched some videos, but nothing seems to help me. Does anyone know a little about the subject or have any documents that can help me?

What arm type? What controller generation?
ROs made the change from sinking to sourcing outputs a while ago.
-
RO 1 - 6 Typically control internal solenoids that are plumbed to the 1A - 3A and 1B-3B ports.
RO 7 & 8 Are wired to the connector.
-
RO7 and RO8 are controlling the signal status of the associated pins on the EE-connector.
So for instance when RO7 is turned ON, pin 7 in the EE-connector will be energized with +24VDC.The amount of current available for the RO-signals are however limited to max 200mA.
Maybe your fuse has blown?
-
RO (robot outputs) are used for robot tooling. They are not used to send signals to external devices other than tooling. Sounds like you need to use Digital output ---DO
-
Did you enable the interconnections? How do you control the DIs and are they really working?
-
Put a voltage meter between the RO 7 pin and the pin 12, 0v. Then manually toggle the RO and see if it shows voltage.
