Message sent to LoRaWAN Port number 1 in every connection to LoRaWAN Server
4 Bytes: HUR Device Id
1 Byte: Frame Type (Lower 4 bits) and Package Number (Upper 4 bits). If Package Number is 1 or more that means the package splitted.
0x00 : means status package for device status and package is the first package
1 Byte: Number of I/O Slots available in HUR device
1 Byte for each Slot (4 bytes for 4 Slots): Slot Types available in HUR device
Available Options: 'HUR_8_DIGITAL_IN', 'HUR_8_DIGITAL_OUT', 'HUR_8_ANALOG_IN', 'HUR_5_ANALOG_OUT'
1 Byte: LoRaWAN target port for I/O data
4 Bytes: RTC Time
3 Bytes: HUR Device firmware version
N Bytes (maximum 22): LKM Device name configured by userI/O Data Message
Message sent to LoRaWAN configured port and minimum send interval can be configured by user
4 Bytes: HUR Device Id
1 Byte: Frame Type (Lower 4 bits) and Package Number (Upper 4 bits). If Package Number is 1 or more that means the package splitted.

MODBUS DETAILS - OUTPUT MODELS
Protocol
Modbus TCP
Modbus Address
Default value is 0x01

Data Format
There are 2 predefined formats
Parsed Data As Objects: Sends I/O values in ASCII readable fromat
Parsed Data as Modbus Frame: Send just like the response of Modbus query as hex data (smaller data size)
I/O LOGIC FUNCTIONS
All versions of HUR Series Modbus TCP Remote Input/Output (I/O) Devices support I/O Logic Functions which can be used to make field automation by using HUR Series itself in the field. As an example, device can be programmed to Turn ON Output or send status of input values to MQTT server or LoRaWAN Server when an input dedected. There are many combinations available.
I/O Logic Commands
16 commands available in Multi Slot Models
8 commands available in Single Slot Models
Condition Slot and I/O
HUR can check programmed input or output of selected slot. This can be any of the available slot (Analog Input, Digital Input, Analog Output or Digital Output)
Condition Command
For Analog Input and Analog Output: HUR can check if the selected I/O value is Higher or Lower than user specified value
For Digital Input and Digital Output: HUR can check if the selected I/O value is ON, OFF or its State Changed (from ON to OFF or OFF to ON)
Condition Duration
HUR can check the command for user defined duration and function is only triggered when command is true for specified duration
Result Slot and I/O
This is the affected input or output number of slot for triggered command. This can be any of the available slot (Analog Input, Digital Input, Analog Output or Digital Output)
Result Command
For Digital Output and Analog Output: HUR can set output to specific value. It can be On, Off or State Change for Digital Output model and can be user defined value for Analog Output Model
For All Slot Models: HUR can send MQTT message or LoRaWAN message for specified slot when command is triggered
Wait Before Next Check
Once the command is triggered, HUR can wait for next check of command based on user defined duration
Examples
Examples applies to models with the mentioned hardware
HUR can send MQTT message for selected slot if an Analog Input Value is Higher than 10mA.
HUR can send LoRaWAN message for selected slot if an Analog Input Value is Lower than 10mA.
HUR can set Output On for selected Digital Output slot if a Digital Input value is OFF
