Abstract

A communications system for use in a well includes a communications link and a plurality of nodes coupled to the communications link. The plurality of nodes include a transmitting node and responding nodes. The transmitting node adapted to transmit a predefined command (e.g., a special read command), and the responding nodes each includes a control device adapted to respond to the predefined command by transmitting a data block.
