Glossary
DX83 Ethernet Bridge Acts as a communications bridge between the Modbus RTU network
(Gateway) and Modbus/TCP or EtherNet/IP host systems and includes
the ability to configure the network using a Web browser interface .
DX80 Gateway SureCross™ DX80 wireless network master communication device used
to control and initiate commands to other devices in the system; serves
as a “portal” from one network to another and communicates between
the wireless network and the central control process .
DX80 GatewayPro Combines the standard Gateway and the DX83 Ethernet Bridge into one
device .
DX80 Node SureCross DX80 slave device in a wireless network .
Ethernet An access method for computer network (Local Area Networks)
communications, defined by the IEEE as the 802 standard.
EtherNet/IP Allen-Bradley’s DeviceNet running over Ethernet hardware .
gateway A general network device that connects two different networks .
master Maintains the timing clock for all devices within the network and initiates
all communications with the slave devices .
Modbus A master-slave communications protocol typically used for industrial
applications .
Modbus/TCP An open standard protocol very similar to Modbus RTU except that it
uses standard Internet communication protocols .
node Any communications point within a network
slave Network slave devices communicate to the network master when
communications are requested; slave devices do not initiate
communications with the master and slave devices do not communicate
with each other .
TCP/IP Transfer Control Protocol / Internet Protocol . Several layers in the OSI
model that control the transfer and addressing of information .
