2. The term gateway refers to the Anybus Communicator e Hexadecimal values are written in the format OxNNNN where NNNN is the hexadecimal value e Decimal values are represented as NNNN where NNNN is the decimal value e As in all communication systems the terms input and output can be ambiguous because their meaning depend on which end of the link is being referenced The convention in this doc ument is that input and output are always being referenced to the master scanner end of the link Glossary Term Meaning ABC Anybus Communicator Broadcaster A protocol specific node in the configuration that handles transactions destined to all nodes RTU Modbus RTU Command A predefined transaction Configuration List of configured nodes with transactions on the subnetwork Fieldbus The higher level network to which the communicator is connected Fieldbus Control System Fieldbus master Frame Object Low level entities which are used to describe the different parts of a Transaction Monitor A tool for debugging the gateway and the network connections Node A device in the configuration which defines the communication with a node on the subnetwork The network that is logically located on a subsidiary level with respect to the fieldbus and to SURE WON which the Anybus Communicator acts as a gateway Transaction A generic building block that is used in the subnetwork configu
