Vega TP-11 / User Manual
4 COMMUNICATION PROTOCOL – version 2.0
This part describes the TP-11 data exchange protocol with LoRaWAN
In fields consisting of several bytes, the little-endian byte order is used

CONVERTER TP-11 TRANSMITS THE FOLLOWING TYPES OF PACKETS

1. Packet with current readings

From connected heat meter, sent regularly or by the request or by the one of "Reason
of sending message" field events.
Size in bytes Field description
1 byte Packet type, this packet == 1
1 byte Battery level, %
Over limits («0» – there is no, «1» - there is)
1 byte
Time of current readings in that packet (unixtime UTC)
4 byte
1 byte Current device temperature
2 bytes Current low threshold (mА*100)
2 bytes Current high threshold (mА*100)
1 byte Reason of sending message
1 byte TP-11 inputs/outputs state
2 bytes Measurement current of connected sensor (mA*100)
"Reason of sending message" field codes
Code
0x00
0x01
0x02
0x03
0x04
0x05
"Inputs/outputs state" bit field decoding
Bits Field description
0 bit Power (0 – battery, 1 – external)
1 bit Security input 1 (0 - unclosed, 1 – closed)
2 bit Security input 2 (0 - unclosed, 1 – closed)
3 bit Output 1 (0 – off, 1 – on)
4 bit Output 2 (0 – off, 1 – on)
5 bit reserve (always 0)
Revision 12 of 12 October 2021
Value
Sending packet by the time
By the security input 1 triggering
By the security input 2 triggering
External power state was change
Measurement is out of the specified limits
Transmitting by the request
network.
