5.1 Parameter usage
5.1.1 Parameter number, resolution and data format
Parameter number and Modbus data address are the same. They are listed in column “Par/Addr” as decimal number.
E.g. P001 is parameter 001 and has Modbus data address 1.
All temperature related parameters are given in °C for Modbus. Only in the user interface values can be shown in °F.
Parameters without multiplier have a resolution of 1. Parameters with multiplier 10 have a resolution of 0.1.
For example, the default value of the Comfort temperature set point (P300) is 20.0°C and the value read via Modbus is
200 (because multiplier 10 is used for P300).
The multiplier is only used for Modbus data access. On the user interface, the values are displayed in normal resolution.
Parameter with values below 0 (zero) are given as signed integer values.
5.1.2 Modbus access (TRA-F121-A only)
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 parameter is defined in column “R/W”. Most parameters can be read and written
defined as “R/W”. Read only parameters are defined as “R”.
