4 COMMUNICATION PROTOCOL

This part describes the SI-11 communication protocol with LoRaWAN
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
1 byte Packet type, this packet == 1
1 byte Battery charge, %
1 byte Values of basic settings (bit field)
4 bytes Reading time for values in this packet (unixtime UTC)
Temperature, °С
1 byte
4 bytes Input 1 reading (depending on the type – number of pulses or
status: 0 – open, 1 - closed)
4 bytes Input 2 reading (depending on the type – number of pulses or
status: 0 – open, 1 - closed)
4 bytes Input 3 reading (depending on the type – number of pulses or
status: 0 – open, 1 - closed)
4 bytes Input 4 reading (depending on the type – number of pulses or
status: 0 – open, 1 - closed)
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.
