ABSTRACT:
A method and apparatus for communicating between a host station and a plurality of slave stations, each detachably connected to a junction box permanently affixed at a node in a loop-type network. Each junction box has a variable code input which may be used as the system address for any slave station connected at that particular node. The system address may be input by the junction box into a predetermined location in the system transmission frame for access by the attached slave station or may be input separately by the junction box into the attached slave station in order to permit the slave station to read information in a particular slot of the transmission frame or write information to such slot.
