13. Modbus settings
Supported functions:
1. Read holding registers (0x03)
2. Write single register (0x06)
3. Write multiple registers (0x16)
1. Read holding register start addresses:
from 0 to 195:
0 – Valve output riser
(1=output closed - valve is open, 0=output open, valve
is closed)
1 – Valve output pwm riser
(valve open in percentage: 0% .. 100%, unsigned decimal)
2 – Temperature value
(valve open in percentage: 0% .. 100%, unsigned decimal)
3 – Set temperature
(temperature in °C with one decimal place precision,
unsigned decimal --> example: 529 = 52.9°C)
4 – Status(alert)*
- 0
- OK
- 1
- temp too low/high
- 4
- sensor closed (short circuit)
- 5
- sensor open (sensor not connected etc...)
Example: To get riser 6 temperature
Formula: (6(Riser) - 1) × 5 + 2 (Temp Value) = 27
2. Write single register – data can be written into start addresses:
from 300 to 331
- from 400 to 435
3. Write multiple register – data can be written into start addresses:
- from 300 to 331
- from 400 to 435
