Registers

Minimal P1 Modbus Dongle firmware version for using with the Teltonika TeltoCharge = 1.2.1

update instruction : update

Default settings

The default settings are:

Modbus device id: 43

RS485 : 8E1 38k4 bps (8 bits, even, 1 stop, 38400 baud)

P1: 115200 8N1 = SMR v4 and v5 (EU) smart meters. Older smart meters (in the Netherlands v2/v3) use a additional power supply for the modbus dongle and FC06 register 6 should be true (1).

Registers

The Dongle supports FC03 and FC06 registers.

FC03 - P1 data

All registers are :

• uint32 (4321) values

• N/A = 0xFFFFFFFF

Registers 10, 12 and higher are implemented in firmware version 1.2.0+. Registers 38 - 48 are available from version 1.2.1.

register	desciption	unit/value
0	energy meter sample timestamp	epoch UTC
2	energy_delivered_tariff1	Wh
4	energy_delivered_tariff2	Wh
6	energy_returned_tariff1	Wh
8	energy_returned_tariff2	Wh
10	energy_delivered_total ( used in eg SE)	Wh
12	energy_returned_total ( used in eg SE)	Wh
14	power_delivered	W
16	power_returned	W
18	U1	mV
20	U2	mV
22	U3	mV
24	I1	mA
26	I2	mA
28	I3	mA
30	Gas Timestamp	epoch UTC
32	Gas delivered	Liter ( = 1/1000 m3)
34	Water Timestamp	epoch UTC
36	Water delivered	Liter ( = 1/1000 m3)
38	power_delivered_l1	Watt
40	power_delivered_l2	Watt
42	power_delivered_l3	Watt
44	power_returned_l1	Watt
46	power_returned_l2	Watt
48	power_returned_l3	Watt

FC03 - Device information

The registers below are available from firmware version 1.2.0.

100	Device ID (see FC06 #0)
102	serial config (see FC06 #2)
104	baudrate (see FC06 #4)
106	Pre4 meter ( see FC06 #6)	only usefull in the Netherlands
108	firmware version	MMmmpp MM = Major mm = minor pp = patch eg. 1.2.0 = 66048 (dec) = 010200 (hex)
110	Static Dongle name, so its clear that this is the P1 Modbus dongle	P1M<hw> hw = hardware. On this moment 3. ascii formatted. So it will be : P1M3 = 1345408307 (dec) = 50 31 4D 33 (hex)

FC06

Implemented in version 1.1.0+.

register	description	value	default
0	device id	0 - 255	43
2	serial config	see below
4	baudrate	0 - 4 = { 9600, 19200, 38400, 57600, 115200 }	38400
6	Pre4 meter	true / false ( 0 / 1 )	0
