Chapter 1 – Introduction

Theory of Operation

This manual will refer to two types of SCADA communications to pologies, Peer to
Peer (P2P) and Modbus.

The Peer to Peer topology
and digital I/O is communicated between the Master and Slave.

The Modbus topology
Modbus slaves. The Modbus master is responsible for requesting data from a
respective Modbus slave.

The ‘RT’ serie s RTU’s have se veral unique functions and features and has been
designed to replicate a wired sensor system. Transmission distances of up to 40 miles
(64 km), (depending on the radio type and with modified antennas), user
programmable sample/polling rates from 10 sam ples/sec to one sample every 20
seconds, programmable transmission retries, user programmable “full scale”
engineering units allow users to enter full scale for a respective sensor, just to name a
few.

The hardware architecture for RT series RTU’s are identical. Number of analog or
digital I/O depends on the type of RTU. Each respective RTU has Bi-directional
analog signal flow.

Other features include:

-Battery backup and in -circuit charging sys tem,

-MODBUS-RTU-Slave Enhancements,

-Programmable main voltage failure alarm,

-Low and high input voltage alarm,

-Communications failure alarm,

-Programmable resting voltages on communication failure,

-Programmable Output to Active High or Low during Communications Failure,

-Report by exception if a respective input changes by a +/- percentage,

-Configurable Inputs to Digital, Frequency or Accumulato r/Total.

An enhanced monitoring and configuration windows based program, allows you to
configure each controller as well as monitor data.

consists of one “Master” and one “Slave” RTU. Analog

consists of one Modbus Master, and as many as 255

Your system may consist of two RT type wireless analo g bridges or RTU. In Peer to
Peer mode, one controller must be programmed as the master and the other as the
slave. It is critical that your system be programmed properly. Confi rm your system
configuration before using your system.

All configuration parameters may be retrieved by connecting to the respective
device’s serial configuration port. The wireless type and other parameters may be
adjusted or viewed.

For Peer-to-Peer mode, check and confirm the following:

___ Your system consists of one MASTER and one SLAVE. Do not allow two
masters or two slaves to communicate with each other. The devices may communicate
but a systems failure will occur.

___ Make sure the system ID’s and RF-Network ID’s match.

WARNING:
ID numbers for the Master and Slave must match and must not be repeat ed with
any other Master/Slave pairs with the same RF-Network ID within the radio
range of each respective wireless pair. Doing so will cause cross talk between
master/slave pairs.

___ Make sure both Master and Slave have an antenna attached and installed correctly.

___ Make sure that the input power supply doe s NOT exceed 28 Vdc.

___ Make sure that the input power supply does N OT fall below 8.5 Vdc.

___ When power is applied to both the master and slave both units will communicate
with each other.

For Modbus Slave RTU mode, check and confirm the following:

___ Your system does not consist of two RT RTU/devices with the same Slave ID
numbers.

___ Each RTU/device has the same Radio ID and RF-Network ID numbers. Your
Modbus Master device will need to be connected to our Packaged Modbus Modem
(PMM) and will need to be configured with the same Radio ID and RF-Network ID
numbers as the Modbus Slave devices. The PMM may be configured to allow for an
RS-232 or RS-485 communications port.

Modbus Overview

This section is written for the person who will use the RT series RTU’s with Modicon
Modbus protocols for communication in Modicon programmable controller
applications. It describes the different types of Modbus registers supported. The RT
Series RTU’s support Modbus, Slave RTU mode.

The Modbus protocol provides the internal standard that the Modicon controllers use
for parsing messages. During communications on a Modbus network, the protocol
determines how each controller will know its device address, recognize a message
addressed to it, determine the kind of action to be taken, and extract any data or other
information contained in the message.

All of the RT series RTU’s use a common Modbus communications protocol. All data
is sent and received raw units.

Engineering Note: It may be necessary to force your PLC or Modbus master device
to delay between Modbus packet transmissions. Some devices transmit without a
break in data packets. Because of the nature of half-duplex radio you may need to
configure or program your device with a 30-50 mS delay between packets and a 1.5-

2.0 second timeout.

Modbus Data: Some Modbus devices send data differently than others. This example
shows Slave address 9, using fu n ction 3 and 16. It also shows he full data address of

40001. The RT series RTU’s do not send the full address. The Modbus protocol
allows a system to assume the data address based on the function type. This is true of
all Modbus functions for the RT series RTU’s.

09 03 9C 40 00 01 91 7E
09 10 9C 40 00 01 02 00 00 9E 54

09 = Slave 9
03 = Read Holding Registers
9C = Starting Address High -\
40 = Starting Address Low -/ 40001
00 = Number of Points High-\
01 = Number of Points Low -/ Read 1 Point
91 = Check Sum
7e = Check Sum

This is an example showing what data would look like for
the RT series RTUs.
09 = Slave 9
03 = Read Holding Registers
00 = Starting Address High -\
00 = Starting Address Low -/ 40001
00 = Number of Points High-\
01 = Number of Points Low -/ Read 1 Point

Peer to Peer Overview

Peer to Peer mode can be described as a Wireless Signal Re plicator. 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 conf igured 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.

Power: 10.5~28 Vdc

Most DC power supplies rated from 10.5 to 28 Vdc @ 1000mA, will work with the
RT12-4444-9T-W20. Do not use a power supply rated less than 1000mA. Doing so
may cause the RT12-4444-9T-W20 to continuously reset. Make sure that the power
supply voltage is maintained between the programmable HIGH and LOW supply
voltage limits or an alarm may occur. If a rechargeable battery is used or if you ar e
supplying voltage to a sensor using the same power used to power the RT12-4444-9T­W20, then the input volt age will need to be adjusted to th e proper voltage to mainta i n
respective equipment. Never exceed 28 Vdc. Damage by overheating to the controller
will occur causing the system to malfunction.

Data Activity LED Indicators

The RT12-4444-9T-W20 RTU is equipment with four LED indicators. The
RED/GREEN pair labeled “SERIAL”, indicate data transmit and data received. The
RED LED will blink when data is being transmitted The GREEN LED will blink any
time data is received, this is true for the MASTER and SLAVE.

Link/Sanity LED Indicators

The yellow LED indicator labeled “Status” indicates proper system operation. The
second yellow LED indicator, labeled “Error”, will flash any time an alarm is
programmed and the respective alarm is active.

Serial RS-232 Interface

Used to configure the RTU. See “Software Setup”.

The RT12-4444-9T-W20 has two rows of 10, screw type, connections. Using a

Typical Application: 4-20 mA to Voltage Conversion

This section will describe how a typical system is converted from a 4-20mA or 0­20mA current signal to a 1-5Vdc or 0-5Vdc voltage signal.

The RT series RTU’s do not allow for a direct 4-20mA connection. A s imple 250
Ohm, 1%, ¼ Watt, resistor from the input of the respective terminal to ground will
convert the current signal to a voltage signal. If a 250 Ohm resistor is not available a
249 Ohm, 1%, ¼ Watt, resistor will work.

The same example is true for a 0-20mA current signal. The only exception is the
voltage will swing from 0-5Vdc. If a current source is applied to a respective input
without a resistor the data will not be correct and a signal error will occur.

The example below shows analog Input 1 converted from 4-20 to 1-5Vdc. Keep in
mind, if an RTU is used in Peer to Peer mode, the receiving device will output a 1­5Vdc voltage on the respective output.

Current Controller Settings

This configuration block will allow you to set the res pective RTU parameters such as
ID, subnet, polling rate, etc. These setting are vital

to the operation and performance

of your wireless system.

Parameters not set correctly may cause the system to malfunction or not communicate.
This block will affect different fields depending on the Wireless Type.

ID: Displays the current controller ID number between 0 and 255.

!WARNING! In Peer-to-Peer Mode, the ID numbers for the Master and Slave must

match and must not be repeated with any other Master/Slave Pairs with the same RF­Network ID within the radio range of each respective wireless pair. Doing so will cause
cross talk between master/slave pairs and may cause harm to the equipment attached.

Polling Rate: In Peer-to -Peer mode, this parameter determines the sampling rate of
data passed between the Master and Slave controllers. It is also the update rate for the
Master and Slave’s analog and digital I/O. This parameter has no affect in Modbus
mode. The Master is responsible for starting the communications process. Therefore the
Polling rate is only configured on the Master controller.

If your system is configured on Peer-to-Peer mode, by default, if the Slave unit does not
receive a response from the master within 20 seconds of any polling seque nce, and if the
”Set Rest Voltage On Comm Error” is enabled, an alarm will sound on the Slave unit
and depending on alarm parameters set, would cause the Slave’s outputs to be set with
the user defined resting voltages.

Retries: In Peer-to-Peer mode, this parameter
determines the number of consecutive failed polling
attempts before a communications failure occurs. It
is not recommended to set the number of retries
higher than 10 attempts. Large numbers may cause
an unnecessary delay in communications failure
response time; a low number may cause the system
to prematurely fail. This parameter has no affect in
Modbus mode.

Output Power: This parameter determines the RF
Power output on some RTU’s. If a respective RTU
does not support a variable RF power out the
parameter will continue to display “Output Power”.

The “ID” field has a dual purpose, as the controller number when in peer-to-peer
mode and the Modbus slave address field when in MODBUS mode.

If Modbus is selected, the Radio ID will automatically appear and the “ID” field will
automatically change to “MODBUS ID.”

If your controller is programmed in Modbus mode, the ID field will change to the
Modbus Slave address. Valid addresses are from 1 to 255. Keep in mind that the
Modbus master you are interfacing to may not support the full spectrum of slave
address IDs. Please refer to your device user’s manual.

P-2-P: P-2-P is also Peer to Peer.

If your system is configured as a Peer to Peer system,
the system must consist of one Master and one Slave.
The Master controller is responsible for starting the
polling sequence.

If your controller is configured as a MODBUS
controller then typical Modbus, Slave, RTU, protocol
applies. Do not allow for duplicate Slave address
within the same system, unless It is on a separate
Radio Id and/or RF-Network ID.

RTU Alarms

The RT series RTU’s have several types of
alarms. Below is a description of each alarm. To
modify or change any of the alarms, click on the
respective box or boxes, and press the “Send
Parameters To Device”. Make sure you are
“Connected”. Alarms are local to the RTU. Each
RTU has a built in beeper alarm. Most alarms
will sound at the master as well as the slave units.
Most of the alarms apply even in Modbus mode.

Update On Change: Not used at this time and is used
for future enhancements.

Alarm On Comm Fail: If enabled, will sound an
alarm on a Local RTU Level. If in peer to peer mode,
the alarm may sound at the Master as well as the Slave.
A communications failure is determined by repeated,
consecutive, failed attempts made by the Master to
contact the Slave unit. The number of at tempts made
depends on the parameter “Retries”. The slave unit
defaults to a 20 second time out if it does not make
contact with the Master.

Set Rest Voltage on Comm Error: If enabled, will cause a local and remote alarm if
a communications failure occurs. This will also force the analog outputs to the
programmed “Analog Resting Voltages” and if enabled will cause the discrete output
to be set to an active high or active low state. “Alarm On Comm Fail” must also be
enabled. In Modbus mode, the comm. fail delay time is 2 minutes.

This parameter also applies if the respective RTU is configured as a Modbus Slave
device.

Alarm On Input Voltage Limit Error: If enabled will cause a local and remote
alarm if the main input voltage falls below or rises abo ve your set limits. These limits
are located in the same section “Analog Resting Voltages”. This alarm will not affect
any of the outputs; the alarm will cause an audible alarm.

Alarm On Main Power Supply Failure: If enabled will cause a local and remote
alarm if the main input voltage completely fails. The backup battery MUST be
connected for this function to operate properly or a communications failure will occur.
This alarm will not affect any of the outputs; the alarm will cause an audible alarm.

Discrete Output-1 Comm Fail Output: If enabled and a communications alarm occurs,
this parameter will cause DO-1, on all RT series RTU’s, to become “Active High” or
“Active Low”. The Output level will depend on how the output is configured. If
enabled, this output can not be controller in peer to peer or Modbus mode. This feature
was added to notify other equipment of a communications failure. This feature may
also be used to activate an external auditable or visual alarm, such as a Horn or Light.

Input Voltage Alarm Limits

Analog Outputs Resting Voltage

(Note: Four analog outputs available on specific RT-12 series models.)

The RT series RTU’s is capable of monitoring its input voltage. This section w ill
describe how to set and enable the “Input Voltage Alarm Limits”.

If the “Alarm On Input Voltage Limit Error” is enabled and the INPUT supply voltage
rises above the “High Limit” or falls below the “Low Limit” the respective RTU will
sound an alarm.

The alarm will stop sounding when the input suppl y voltage returns to ”normal” by
returning between the +/- limits determined by the “High /Low Limit Dead Band”. The
“Normal” +/- limits are calculated by subtracting the “High/Low Limit Dead Band”
from the “High limit” and adding the “High/Low Limit Dead Band” to the “Low Limit”

The configuration shown above will cause a HIGH alarm if the input supply voltage
rises above 28.0 VDC and will return to normal when the inpu t s upply voltage falls to

26.01 VDC.

The configuration above will cause a LOW alarm if the i nput supply voltage falls below

9.99 VDC and will return to normal when the input supply voltage rises to 11.98 VDC.

(Note: Four analog outputs available on specific RT-12 series models.)

This section applies to Peer to Peer and Modbus systems. In peer to peer mode, the
master and slave communicate with each other and during the comm unication p rocess
they share information. In the event of a communication failure, the updating process
will stop and if the Communications alarm is disabled the analog outputs for the
master and slave will be the last valid update.

A communications error will occur if the number of consecutive failed polling
attempts exceeds the programmed number of re tries. This count is reset if even one
valid communications update occurs before the number of retries expires and if the
RTU is a Modbus device, a communications of 2 minutes must laps.

The analog output resting voltages provide a means to program the voltage outputs in
the event of a communications error.

Due to the nature of wireless systems, communication failures may occur. The RT
series RTU’s allow you to program each of the analo g outputs with a preset level in
the event of a communications failure. Each ana log output can be programmed with
independent levels from 0 volts to 5 Vdc.

If the RTU is programmed to respond to a communications ala rm and a
communications failure occurs, the respective RTU will force the outputs with your
preset levels. The outputs will return to normal once communications is reestablished.

To program the RTU to respond to communications failures select t he “Set Rest
Voltage on Comm Error” and update the configuration by pressing the “Send Changes
To Device”.

(Note: Four analog outputs available on specific RT-12 series models.)

To program each analog resting output voltage, enter a voltage from 0.0 to 5.0, into
each box representing Analog Output 1, Analog Output 2, Analog Output 3, and
Analog Output 4. Then press “Send Resting and Limits Æ Device”. This data is saved
and remains resident within the respective RTU. This process is valid ONLY if the
RTU is “Connected”.

The respective RTU is also equipped with the ability to turn on or off its output if a
Communications error occurs. This is true for the Master and Slave.

The output is an Open Drain output and should be used to sink not s ource current,
1Amp MAX. This typically means that the Output will supply a “Ground” to the
device to turn it on or off.

The respective RTU also has the ability to control its respective Out put during a
communications failure. The output may be configu red to an ACTIVE HIGH or
ACTIVE LOW state during a communications failure. This can be useful as an alarm
output or to turn a device on or off. A “Check” mark next to the “Discrete Output Comm
Fail Enable” will force the output to an active HIGH or LOW, (depending on what is
selected for an Active High or Active Low), during a communications failure. If you
use the output to respond during a communicatio ns failure, you will not have control
using the Modbus protocol. If you wish to use the output for something other than a
comm. failure you will need to disable the “Discrete Output Comm Fail Enable”.
