Runtime Data
6.1
Resolution and data format
All temperature related data are given in °C for Modbus. Only in the user interface values can be shown in °F.
Data without multiplier have resolution 1. Data with multiplier 10 have resolution 0.1.
For example, the default value of Comfort temperature set point (P300) is 20.0°C and the value read via Modbus is 200
(because of multiplier 10 used for P300).
Data with values below 0 (zero) are given as signed integer values.
6.2
Modbus access
The controller supports the following Modbus function cods:
Modbus function code
Data
Read multiple register (0x03)
Read n registers (n x 2 bytes) starting from requested address.
Write register (0x06)
Write 1 register (2 bytes) at requested address.
Write multiple registers (0x16)
Write n register (n x 2 bytes) starting from sent address.
Note: The read/write capability of each data element
is defined in column “R/W”. Most
data can be read and written
defined as “R/W”. Read only
data
are defined as “R”.
