1. A robotic system, comprising:
a first node and a second node; and
a first pair of electrical conductors for differential communication between the first node and the second node so that the first pair of electrical conductors are operable to communicate data signals between the first node and the second node as differential signals, wherein the first node includes a first electrical circuit electrically coupled with the first pair of electrical conductors, and the first electrical circuit is operable to communicate emergency stop signals between the first node and the second node as non-differential signals over the first pair of electrical conductors, wherein the second node comprises a first voltage monitor for sensing a common-mode voltage for the first pair of electrical conductors between the first node and the second node.
