  • Page 37: Operation Via Modbus

    Seen from the AS-Interface, the AS-i/Modbus gateway is an master, because it ini- tiates AS-i communication and the AS-i slaves only respond. On the side of Modbus the AS-i/Modbus gateway only reacts after an query from an Modbus-Master. Therefore it is an Modbus-slave.
