•“Bus” topology with VW3 A8 306 TF3 drop boxes: This topology uses VW3 A8 306 TF3 drop boxes to connect each of the Modbus slaves to the main section of the Modbus network. Each box should be placed in the immediate vicinity of the Modbus slave it is associated with. The cable for the main section of the Modbus network must have male RJ45 connectors (like the VW3 A8 306 R•• cable used for the “star” topology). The lead between the drop box and the slave or the Modbus gateway is an integral part of this box. The connections are shown below:
