Communication
concept
The Interbus-S system is able to communicate with a number of external devices, depending
on the number of process words occupied by each unit. The robot may be equipped with one
or two DSQC 351. The Interbus-S inputs and outputs are accessible in the robot as general
inputs and outputs.
For application data, refer to Interbus-S, International Standard, DIN 19258.
Below is shown an outline diagram of the communication concept:

Termination link A link is connected between pins 5 and 9 in the plug on the interconnection cable connected
to the OUT connector of each unit. The link informs the Interbus-S unit that more units are
connected further out in the chain. (The last unit in the chain does not have a cable connected
and therefore no link).
