4 COMMUNICATION PROTOCOL 

This part describes the SI-11 communication protocol with LoRaWAN

®

 network.  

 

In fields consisting of several bytes, the little endian byte order is used 

VEGA SI-11 PULSE COUNTER TRANSMITS THE FOLLOWING TYPES OF PACKETS 

1.

 

Packet with current readings 

Sent regularly on LoRaWAN port 2. 

Size in bytes 

Field description 

Data type 

1 byte 

Packet type, this packet == 1 

uint8 

1 byte 

Battery charge, % 

uint8 

1 byte 

Values of basic settings (bit field) 

uint8 

4 bytes 

Reading time for values in this packet (unixtime UTC) 

uint32 

1 byte 

Temperature, 

°

С 

int8 

4 bytes 

 

Input 1 reading (depending on the type – number of pulses or 
status: 0 – open, 1 - closed) 

uint32 

4 bytes 

Input 2 reading (depending on the type – number of pulses or 
status: 0 – open, 1 - closed) 

uint32 

4 bytes 

Input 3 reading (depending on the type – number of pulses or 
status: 0 – open, 1 - closed) 

uint32 

4 bytes 

Input 4 reading (depending on the type – number of pulses or 
status: 0 – open, 1 - closed) 

uint32 

The counter has internal clock and calendar; time and date are factory set. When sending 

a packet with the current readings, the device uses the data taken at the nearest time, which is 
multiple to the interval according to data collection period: 

 

1 hour period: the readings of the beginning of the current hour are sent; 

 

6 hours period: 00:00, 06:00, 12:00, 18:00 readings are sent; 

 

12 hours period: 00:00, 12:00 readings are sent; 

 

24 hours period: the readings of 00:00 of the current day are sent.
