INSTALLATION RECOMMENDATIONS

Input conductors must go through the system plant separated from the output and power supply conductors, in grounded

conduits.

OPERATION

In the frontal panel are found an mini-B USB connector, a SMA connector for the antenna, a setup button and two LEDs for status

indication. See Fig. 4.

Fig. 3 - AirGate-Modbus frontal panel

USB

The USB interface of AirGate-Modbus is used for setup. Depending on the operation mode set, this interface can be connected to a

PC functioning as master of the Modbus RTU network.

SETUP BUTTON

When press the button, AirGate-Modbus enters setup mode and waits the configuration by the USB interface. If there is no

communication through the USB interface, after 1 minute, this will go back to normal functioning.

LEDS

When turning the equipment on, the Status LED starts to flash quickly until the AirGate-Modbus

connects to a wireless network. In the moment that the AirGate-Modbus is connected to a wireless

network, the Status LED remains turned on.

When the setup button is pressed, the Status LED flashes slowly until AirGate-Modbus quits

operation mode. There are 3 possible ways to quit setup mode:

Clicking in the setup button again;

Applying a configuration successfully;

Waiting 1 minute.

The Communication LED flashes to show that the device is receiving packages through any of its

interfaces and is forwarding correctly. The speed of the flashing is according to the communication

speed.

When the Firmware of the AirGate-Modbus is being updated, the Communication LED will start to

flash and the LED Status will be off.

AirGate-Modbus

INTAB INTERFACE-TEKNK AB 5/22

OPERATION MODES

AirGate-Modbus can be configured with 4 different operation modes:

RS485-MASTER

Simple Forwarding between RS485 and IEEE 802.15.4

In this mode AirGate-Modbus uses the RS485 interface to communicate with a Modbus Network. And the wireless interface to

communicate with other AirGate-Modbus devices in RS485-SLAVES operation modes.

RS485-SLAVES

Simple forwarding between IEEE 802.15.4 and RS485

In this mode AirGate-Modbus has the objective of continuing the Modbus network. It uses the wireless interface to communicate

with another AirGate-Modbus, where the network master is located. The RS485 interface is used to communicate with Modbus

slaves.

As of firmware version V1.23, when operating in this mode of operation, the AirGate-Modbus can begin to automatically perform

the repeater function. This function does not require any special configuration. When configured in this mode of operation, after

the AirGate-Modbus finds a father (RS485-Master, USB-Master, Multi-Master, or even another RS485-Slaves) it then is able to offer

the option of having children, allowing other AirGates that are also operating with RS485-Slaves to automatically pair with it.

USB-MASTER

USB Routing for RS485 and IEEE 802.15.4

In this mode AirGate-Modbus uses the USB interface to communicate directly with a Modbus master and its RS485 interface to

communicate with a Modbus slave’s network. The wireless interface is used to communicate with other AirGate-Modbus devices in

RS485-SLAVES operation mode.

MULTI-MASTER

Multiplexing of the USB and RS485 for IEEE 802.15.4

In this mode AirGate-Modbus uses the RS485 and USB interfaces for the multiplexing of Modbus masters. The masters must be

directly linked to these interfaces. The wireless interface is used to communicate with other AirGate-Modbus devices in RS485-

SLAVES operation mode.

When this operation mode is used, a Timeout is needed to ensure that each of the masters have an usage time in the network. This

Timeout is automatically adjusted by DigiConfig software according to the baud rate used by the interfaces, as it can be seen in the

chapter “CONFIGURATIONS - AIRGATE-MODBUS” in the section “TIMEOUT”. Depending on the number of slaves and of the

response time of each slave, it may be necessary to adjust this Timeout to reduce possible communication errors.

It's important to emphasize that the Timeout configured for this operation mode refers to a time interval managed automatically

by the AirGate-Modbus. The network masters plugged in each one of the USB and RS485 interfaces must have their Timeouts

configured with double the time set in AirGate-Modbus Timeout.

COMPLEMENTARY MODES

Only devices with distinct functions form a wireless communication network. The operation form of some modes also imposes

connection restrictions. The modes compatible with the wireless connection may be seen in Table 1:

* The RS485-SLAVES operation mode only begins to offer the option of having children (behaving as a repeater) after having paired

with a father that is already operating on the network. This entire process is done automatically, without any intervention from the

operator.

USING THE OPERATION MODES

WIRELESS SEGMENTS IN ANY POINT OF AN MODBUS NETWORK

Division of a wired network in wired segments interconnected by wireless segments. The division occurs far from the Modbus

master. It uses the RS485 port AirGate-Modbus to communicate with the master and the slaves. Additional wireless segments can

be inserted. Fig. 5 illustrates this possible application.

Fig. 4 - Wireless segments in any point of a Modbus network

WIRELESS SEGMENTS CLOSE TO THE MODBUS MASTER

Division of a wired network in wired segments interconnected by wireless segments. Wireless segments located close to the

Modbus master which communicates by USB port. It allows the AirGate-Modbus using as a USB-RS485 convertor for the first wired

segment. Fig. 6 illustrates this possible application.

Fig. 5 - Wireless segments close to the Modbus master

WIRELESS SEGMENTS CLOSE TO MULTIPLEXED MODBUS MASTERS

Multiplexing of 2 masters, one connected to the USB interface and another to the RS485. Wireless section located close to the

Modbus masters. It also allows the usage of a single master in any of the 2 interfaces (USB or RS485).

LONG REACH APPLICATION

In seeking to expand the network, in order to obtain a greater distance, it is possible to assemble a tree shaped topology. As

exemplified in Fig. 6, to expand the network, an AirGate-Modbus configured as a RS485-SLAVES (Firmware > 1.23) was inserted

with the same PAN ID (5670). In another segment, two AirGates were assembled using the RS485 interfaces, an AirGate-Modbus

operating the RS485-SLAVES mode, and an AirGate-Modbus operating in RS485-MASTER mode. In this segment a new PAN ID

(5671) was created, starting a new star network.

AirGate-Modbus

INTAB INTERFACE-TEKNK AB 8/22

RESTRICTION

In case there is the need to implement a tree-shaped network, a restriction must be observed. Due to issues imposed by Modbus

standard, Modbus slaves must not be connected between AirGate-Modbus as signed in Fig. 7.

Fig. 7 - Restriction

SETUP SOFTWARE

The DigiConfig application is a Windows® program used for the configuration of the AirGate-Modbus. For its installation, execute

the file “DigiConfigSetup.exe” from the CD. When installing the setup software, the USB Serial Port driver of AirGate-Modbus may

To edit the configurations of the AirGate-Modbus, after clicking the Search button, you must select it in the tree to the left of the

main screen.

To quit “setup mode“, you must press the SETUP BUTTON again, “Cancel”, or “Apply” a configuration. In this moment, the device is

reset and starts to operate according to the last applied configuration.

DETERMINATION AND SELECTION OF THE SERIAL PORT (COM) - WINDOWS

DETERMINATION

The serial port associated to the AirGate-Modbus is automatically determined by the operational system a few instants after the

connection of the AirGate-Modbus. The user may easily identify or alter the COM port associated to the AirGate-Modbus accessing

the Windows® “Device Manager”:

Control Panel / System/ Hardware / Device Manager / COM & LPT Ports

It’s also possible to open the “Device Manager” executing the following command: “devmgmt.msc”.

After opening the “Device Manager” it's possible to verify which is the Serial Port (COM) associated to the AirGate-Modbus. As it

can be seen in Fig. 13 the AirGate-Modbus is associated to COM7.

AirGate-Modbus

INTAB INTERFACE-TEKNK AB 11/22

Fig. 13 - Determination of the COM Port

SELECTION

In case it's necessary to modify the Serial Port (COM) associated to the AirGate-Modbus select “USB Serial Port (COM X)” where the

AirGate-Modbus is connected. Access "Action/Properties" and in the "Port Definitions" tab click "Advanced...", according to Fig. 14.

In case this tab does not appear, the driver was not installed correctly and the DigiConfig software must be reinstalled. In the

“Advanced definitions for COMX” window change the parameter “COM port Number:” for the desired COM, as indicated in Fig. 15.

Some serial ports may be marked as In Use. Only select one of these ports in case you are sure that it is not being used by another

peripheral of your computer.

In some situations the serial ports may be marked as in use even when the associated device is not installed anymore in the

computer. In this case it is safe to associate this port to the AirGate-Modbus.

Fig. 14 - Accessing the advanced configuration of the COM port

IMPORTANT RECOMMENDATION

To improve the communication of the USB interface it is recommended the configuration of a Latency Timer. This parameter may

be modified accessing “Advanced definitions for COMX” window according to Fig. 14.

Later it's possible to verify, according to Fig. 15, the “Latency Timer (ms): which must be altered to 4.

CONFIGURATIONS - AIRGATE-MODBUS

BASICS

PAN ID

Choose a common identifier for each wireless network. All of the AirGate-Modbus devices from a same network must be

configured with the same PAN ID.

MODBUS ADDRESS

Each AirGate-Modbus must have a unique Modbus address. This address should be set before connecting the device to the

network. Modbus communication frames addressed to AirGate-Modbus will be handled by itself. Frames with any other address

will be forwarded.

This address is set in factory as 248, an invalid Modbus address, to avoid initial conflict with any other already configured Modbus

device in the network and should be changed to a unique address as soon as possible. While in Configuration Mode (status LED

flashing), communication parameters switch to 115200 bps, no parity, 2 stop bits and address 246.

BAUD RATE

Select for each interface the baud rate used by the Modbus network. All of the devices from the network must be configured with

the same baud rate.

PARITY

Select for each interface the parity/stop bits used by the Modbus network. All of the network devices must be configured with the

same parity/stop bits.

TIMEOUT

Timeout (in milliseconds) for the receipt of response bytes to the command sent to the slave station. Calculated automatically by

the software, according to the select baud rate.

For RS485-Master, RS485-Slaves and USB-Master operation modes, this parameter is only shown in the screen to help the setup of

the network master's Timeout, which must have its Timeout time configured with at least the Timeout shown in DigiConfig screen.

For Multi-Master operation mode, this parameter is used by the AirGate-Modbus, and may have its Timeout altered by the

DigiConfig according to what is explained in the section “MULTI-MASTER” of the “OPERATION MODES” chapter. Noting that in this

case the Timeout configured in each network master must be at least double the time configured for AirGate-Modbus.

OPERATION MODES

According to the desired functionality the AirGate-Modbus can be configured with different operation modes. These are

distinguished altering the functions of the communication interfaces, as explained in the “OPERATION MODES” chapter. When

selecting a operation mode in DigiConfig, a figure containing a topology example will help in its setup.

ADVANCED

INTERFRAME TIME

The maximum time allowed (in microseconds) between the receipt of two bytes from a same package. This time is calculated

automatically by DigiConfig software. It must only be modified it any of the network slaves show a high communication error rate.

The "Minimum time” and "Maximum Time" values are shown in DigiConfig and range according to the lowest baud rate selected

for the interfaces in the “Basic Configurations Guide”. When clicking the “Auto” button the text box will be available for altering of

the "Interframe Time” which must obligatorily be within the band.

RF POWER

Alters the value of the transmission of the AirGate-Modbus. Valid values from 0 to 20 dBm.

SECURITY

The encryption of the packages may be enabled by selecting the “Enable Security” box. In case you wish to modify the security key

simply click “Change Security Key” and type a new key in the fields “Typethekeyhere”.

FIRMWARE UPDATE

This DigiConfig tab is used for the firmware update of the AirGate-Modbus.

The following steps must be followed:

1. Locate the "Firmware" tab "Device Setup”.

2. Select "Enable Firmware Update”.

3. Click "Open” and search the new firmware file (".cbin").

4. Press the “Apply” button.

5. Wait the Firmware update process conclusion. The DigiConfig will show a text box with the information AirGate-Modbus

6. The DigiConfig will turn back to the initial screen and the STATUS LED of the AirGate-Modbus will start to flash rapidly.

AirGate-Modbus

INTAB INTERFACE-TEKNK AB 13/22

During the Firmware update process of the AirGate-Modbus, there must not have any

interruption. In case there is power outage, disconnection of the USB cable or interruption of the

Digiconfig software during the process, the AirGate-Modbus will probably cease operating

normally and must be forwarded to the technical support of the supplier.

DATA COMMUNICATION - SERIAL

The AirGate-Modbus possesses two communication interfaces:

•RS485, acting as communication interface with Modbus RTU protocol.

•USB device, acting with the communication interface of Modbus RTU protocol.

RS485 AND USB INTERFACE

The RS485 and USB interfaces may be configured to operate in the following speeds (baud rates): 1200, 2400, 4800, 9600, 19200,

38400, 57600 and 115200. Besides that, it may be configured to operate with one or two stop bits, and in the parities even, uneven

and none.

More details about the implementation of a Modbus devices network via RS485 can be found in the document “Basic RS485 and

RS422 Concepts”, available in the CD which accompanies the product or in the www.novusautomation.com website. The Table 2

DATA COMMUNICATION –WIRELESS

The AirGate-Modbus has a IEEE 802.15.4 Wireless communication interface to connect to the other Novus equipment that uses the

same communication interface. As of firmware version V1.23, the AirGate-Modbus allows, not only communication with other

AirGates, as described in the chapters Operation Modes and Using the Operation Modes, but also the option to communicate the

RHT-Air equipment units, which are Wireless transmitters of temperature, humidity, and dew point. Each AirGate-Modbus can

support the connection of 8 AirGate-Modbus equipment units and 35 RHT-Air equipment units. Each of these 8 AirGate-Modbus

equipment units allows the connection of over 8 AirGates and 35 RHT-Air up to the limit of 4 levels of depth, as illustrated in Fig.

16. This network topology is formed automatically at the moment the network begins. One only needs to configure at least one

AirGate-Modbus as a Multi-Master operation mode, USB-Master or RS485-Master and the other equipment: (i) AirGate-Modbus,

with the RS485-Slaves operation mode; and (ii) RHT-Air, all with the same PAN ID. After the configuration, the equipment units will

automatically be paired based on the best communication link (LQI) that is found.

For a correct functioning of the wireless communication network, it is important for all equipment to have the same firmware

version. If you have AirGate-Modbus equipment with a firmware version below V1.23 and wish to use the new functionalities

available in this version, such as a tree network topology that is totally wireless, or operation with RHT-Air equipment, you only

have to update the firmware of all the equipment or use a AirGate-Modbus with the new version of the firmware operating - such

as RS485-Master - in another PAN ID, connected to interface RS485 in one of the AirGates operating as RS485-Slaves of the first

PAN ID, as shown in the Long Reach Application.

MODBUS COMMANDS

As of the V1.23 Firmware version, the AirGate-Modbus begins to respond to Modbus commands that are forwarded to your

Modbus address, operating as a network slave. Commands forwarded to other slaves will be sent transparently. The Modbus RTU

commands (functions) are implemented and listed below, and they are interpreted by AirGate-Modbus. For more information

about each command and the Modbus protocol in general, access the site www.modbus.org.

READ HOLDING REGISTERS –0X03

This command can be used to read the value of one, or up to the maximum amount of consecutive holding registers, as shown in

the “Holding Registers Table.”

WRITE HOLDING REGISTERS –0X06

This command can be used to write in a holding register, as shown in “Holding Registers Table.”

DESCRIPTION OF SOME REGISTERS

Shows the operation channel that the equipment is operating on the network. It can vary from 11 to 25, where each channel is

equivalent to an operation frequency. Among these 15 possible channels, the network operates on the channel that has the lowest

interference.

States the quality of the reception link of the connection between the equipment and the AirGate-Modbus father with which it is

paired. This value is obtained when measuring the power of the last packet received. This power is measured in dBm, which is a

logarithmic measurement of power in mW. The LQI can vary between -100dBm (worst reception quality) to -15 dBm (best

reception quality).

States the quality of the reception link of the connection between the AirGate-Modbus child whose Modbus address was filled-out

in the ADDR_FILHO register. This value is obtained when measuring the strength of the last packet received. This power is

measured in dBm, which is a logarithmic measurement of power in mW. The LQI can vary between -100dBm (worst reception

quality) to -15 dBm (best reception quality).

LINK QUALITY INDICATOR

To evaluate if the equipment was installed in an appropriate manner, it is recommended to verify the quality of the connection

between each of the AirGate-Modbus and RHT-Air equipment units. This verification should be made by an analysis of registers 36

and 39, while the network is operating. To make this analysis, it is possible to use the Diagnostic tab of the DigiConfig that states

the network typology and the quality of the link between each of the wireless connections in an intuitive fashion.

For equipment operating in ideal conditions, where there are no obstacles and no type of electromagnetic interference, the LQI will

behave similarly to the contents of the graph shown in Fig. 17, where a comparison between different levels of power for the

Distance versus LQI ratio is made.

Fig. 13 –Ratio between Distance and LQI for several power levels

Table 4 lists the values obtained in the LQI reading with an evaluation of the signal quality. This same information can be seen in a

more intuitive fashion on the Diagnostic tab of the DigiConfig Software.

R/W

Configures the parity and how many stops bits will be used in the

operation mode in the RS485 interface of the device. To facilitate

connectivity with devices from different manufacturers, when

configured with ParityNone_StopBits1 or ParityNone_StopBits2, the

device always transmits using 2 stop bits and receives with 1 stop bit.

This allows for communication with devices with both configurations,

but this feature is only available with the RS485 interface.

R/W

Interframe is the time used to characterize the fact that 2 bytes are part

of the same Modbus frame (packet). When two bytes are spaced in less

time than the time configured in this register, they are part of the same

packet. When this time is exceeded, the frame is considered to be

finished.

In this register the Interframe Modbus for USB is configured. When

configured with 1749, it automatically takes on the values according to the

Baud Rate in compliance with the Modbus protocol. If the network master

connected to the USB interface has a high rate of errors, it is possible that

it is not following the Modbus rule. In this case, increasing the value of the

identifies the device on the network. As a standard, since it is a gateway

and to not conflict with other network devices, all of the AirGate-Modbus

leave the factory with the address 248.

When in configuration mode, as explained in the Configuration Mode

chapter, the device always answers for the Modbus 246 address using

the USB interface.

When operating in Multi-Master mode, as explained in the MULT-

MASTER chapter, the gateway uses the Multiplexar function that needs

a time-out to release the interface in case the response does not return

to one of the masters.

The Time-out is configured in this register. This is the maximum amount

of wait time for a response from a slave

LQI RX Father Register

Lists the LQI RX Father, i.e., the quality of the reception link to the

network father. The LQI Rx is a power measurement of the last packet

received by the father. This amount is measured in dBm and varies

between -100dBm (worst reception quality) to -15 dBm (best reception

quality). This register has a value of 0 when the device is in configuration

mode or is the network coordinator (that does not have a father).

ADDR_FILHO register.

This register is used to request the AirGate-Modbus information about

its children.

This register should include the Modbus address of the child that

requires the information contained in the registers 39 to 48.

The information will only be filled out is the Modbus address

corresponds to a device that is in a branch below the one the father

belongs to.

If the Modbus address does not belong to a direct child, the information

will correspond to the child en route to the destination.
