(1) For further information see requirements of the IEC 61158-2 standard
(2) A spur is an unterminated part of the network.
(3) A trunk is the longest cable path between two devices on the fieldbus network, and is the part of
the network which has terminations at both ends. In the Rosemount Tank Gauging system, a
trunk is typically located between the Rosemount 2410 Tank Hub and a segment coupler or the
last device in a daisy-chain configuration.
