acknowledges the data. Each remote radio sends pending data to the master radio that
receives and acknowledges data sent from each remote. In this configuration, there are
multiple remote radios referenced to a single master radio.
Point-Multipoint (Modbus) Network
A network with a single Master radio and multiple Remote radios. The devices cabled to
the radios communicate through the Modbus standard protocol. The Master radio
sends data to a Remote radio based on the Modbus address of the Modbus device. The
data is only sent to the single Remote device based on its address. Each Remote radio
sends its data only to the Master radio. The Master and Remote radios acknowledge
that data was received correctly.
Point-to-Multipoint
A wireless network in which one point (the access point) serves multiple other points
around it. Indoor wireless networks are all point-to-multipoint, and long-range wireless
networks that serve multiple clients usually employ either a single omnidirectional
antenna or multiple sector antennas.
Point-to-Point Network
A network consisting of a single Master radio and a single Remote radio. All data from
the Master is received and acknowledged by one Remote. All data from the single
Remote is received and acknowledged by the Master radio.
Poll
A method of electronic communication.
Power Supply
Device that supplies electrical power to the I/O chassis containing the processor,
coprocessor, or other modules.
Protocol
