2.1.3 Installing add-on devices
General
Add-on devices have an optical interface and must be powered and attached to a
configured base device to be detected by the robot controller. Up to four add-on
devices can be attached to the same base device with maintained performance.
The optical interface on the base device is powered by process power supply and
must also be connected to detect the add-on device. Unpowered add-on devices
shall be placed last, i.e. to the right, otherwise the optical link is broken.
