Device Access Network

This chapter describes how to configure the network for collecting data from terminal devices.

Configure LoRaWAN^® Network

The LoRaWAN^® Network is preloaded by default and cannot be deleted.

Steps:

Click

to select the channel plan. Other parameters can retain their default values or be customized as needed.


Parameter	Description
Channel Plan	Select the channel plan of the network. The options vary by model: -868M: EU868, IN865, RU864 -915M: AU915, US915, KR920, AS923-1/2/3/4 -470M: CN470
Channel	Allow end devices to communicate via specific frequency channels by entering the channel indexes. Examples: 1,40: Enable Channel 1 and 40 1-40: Enable Channel 1-40 1-40, 60: Enable Channel 1-40 and 60 Null: Enable all channels
Additional Channels	Click Add to add channels not defined by the LoRaWAN^® Regional Parameters. This feature only works with channel plans other than US915/AU915/CN470.
Advanced
NetID	The unique identifier used by end devices to identify the network server.
Join Delay	Define the interval during which the end device waits for the Join Accept message after sending the Join Request.
RX1 Delay	Define the delay time after which the end device waits for the first receive window (RX1) to open.
Log Level	Select the level for recording logs.

The device supports adding various types of network.

Steps:

Click +Add to add a new network and configure the basic parameters.


Parameter	Description
Name	Define a unique name for the network.
Protocol Type	Select the protocol type based on the terminal devices: BACnet/IP, BACnet MS/TP, Modbus RTU, Modbus TCP, Modbus RTU over TCP, KNX/TP.

Configure the network parameters according to the protocol type.

BACnet/IP


Parameter	Description
Network Interface	Select network interface for communicating with other BACnet/IP terminal devices.
Advanced
Device Instance Nr	Define the unique identifier of the gateway in the BACnet/IP network.
UDP Port	Set the communication port.
Timeout	Define the time to wait for terminal devices to respond after sending commands each time.
Retry times	Define the number of retries for send commands to terminal devices if there is no response.
Keep Alive Interval	Define the interval for sending heartbeat packets to terminal devices to check their online/offline status. If there is no response after 3 attempts, the terminal device will be considered Offline.

BACnet MS/TP


Parameter	Description
Physical Interface	Select the RS485 interface for connecting to BACnet MS/TP terminal devices.
Baud Rate	Select the serial data transmission rate.
Data Bits	The number of data bits for each character. It is fixed at 8.
Stop Bits	Indicates the end of each data frame, enabling the receiver to determine if a frame is complete. Options: 1, 2
Parity	This is used to detect errors during transmission. Options: None, Odd, Even.
DIP	Enable or disable to add a 120Ω termination resistor across terminals A and B, eliminating signal reflections from the cable ends.
Advanced
Device Instance Nr	Define the unique identifier of the gateway within the BACnet MS/TP network.
MAC Address	Define the unique MAC address of the gateway within the BACnet MS/TP network. Range: 0-127
Max Master	Define the highest MAC address that a device will search for when looking for other masters on the network.
Max Info Frames	Define the maximum number of data frames a device can send before passing the token another device on the network.
Timeout	Define the time to wait for terminal devices to respond after sending commands each time.
Retry times	Define the number of retries for send commands to terminal devices if there is no response.
Keep Alive Interval	Define the interval for sending heartbeat packets to terminal devices to check their online/offline status. If there is no response after 3 attempts, the terminal device will be considered Offline.

Modbus TCP or Modbus RTU over TCP


Parameter	Description
Timeout	Define the time to wait for terminal devices to respond after sending commands each time.
Retry times	Define the number of retries for send commands to terminal devices if there is no response.
Keep Alive Interval	Define the interval for sending heartbeat packets to terminal devices to check their online/offline status. If there is no response after 3 attempts, the terminal device will be considered Offline.

Modbus RTU


Parameter	Description
Physical Interface	Select the RS485 interface for connecting to Modbus server (slave) devices.
Baud Rate	Select the serial data transmission rate.
Data Bits	The number of data bits for each character. It is fixed at 8.
Stop Bits	Indicates the end of each data frame, enabling the receiver to determine if a frame is complete. Options: 1, 2
Parity	This is used to detect errors during transmission. Options: None, Odd, Even.
DIP	Enable or disable to add a 120Ω termination resistor across terminals A and B, eliminating signal reflections from the cable ends.
Advanced
Timeout	Define the time to wait for terminal devices to respond after sending commands each time.
Retry times	Define the number of retries for send commands to terminal devices if there is no response.
Keep Alive Interval	Define the interval for sending heartbeat packets to terminal devices to check their online/offline status. If there is no response after 3 attempts, the terminal device will be considered Offline.
Interframe Delay	Define the delay time between two consecutive Modbus RTU commands.

KNX/TP


Parameter	Description
Physical Address	Define the unique physical address of the gateway within the KNX bus network.
Advanced
Timeout	Define the time to wait for terminal devices to respond after sending commands each time.
Retry times	Define the number of retries for send commands to terminal devices if there is no response.
Keep Alive Interval	Define the interval for sending heartbeat packets to terminal devices to check their online/offline status. If there is no response after 3 attempts, the terminal device will be considered Offline.
