Peer to Peer Overview
Peer to Peer mode can be described as a Wireless Signal Replicator. The product line
of RT series RTU’s can be configured as a Peer to Peer device. Two of the same type
RTU’s are required to create a peer to peer system, one Master and one Slave.
The master or slave is determined by the way It is
configured. The only difference between a master and
slave is, the master is responsible for starting the
communication process.
Both the master and slave must contain the same Radio ID
and Subnet Value. Only the respective peer-to-peer
systems may have the same Radio ID and RF-Network
numbers. Failure to do so will cause erratic output
voltages, AO’s or Digital Outputs, DO’s.
Each respective “RT” RTU device has the same number of Analog Inputs (AI’s),
Analog Outputs (AO’s), Digital Inputs (DI’s) and Digital Outputs (DO’s).
The number and type of I/O will depend on the type of RTU. Each RTU, including
I/O, is described in this manual.
Peer to Peer mode will allow you to transmit a 0-5 Vdc analog input, or a Digital
Input, from a Master device to a Slave device and vice-versa. A master’s analog or
digital inputs, become a slave’s analog or digital outputs, and vice-versa. This allows
for a full-duplex, looped system.
An application example would be a remote PLC with the RT12-2222’s analog and
digital I/O connected to it, this RTU will be configured as a Master. The Slave device
would monitor and control a water well system and would be connected to several
sensors, pump status indicators, current sensor, etc.
The PLC will view the analog and digital signals from the slave device as if the PLC
was connected directly to the several sensors, pump status indicators, current sensor,
etc. See “Typical Application – Well Monitor and Control, Peer-to-Peer” in this
manual.
