Hello
I have been trying to get some tags from a nibe F1145http://www.nibe.eu/Products/Ground-source-heat-pumps/NIBE-F1145/
I use a modbus 40 connected to the heatpump.
http://www.nibe.eu/Products/Accessories/NIBE-MODBUS-40/

Here I have found out that I need to use -1 to the the rigth regestery. And that eks.
BT1 Outdoor temp is a WORD type under the <modbus master="" configurator="">
I wounder if it is any webpage og tabel that gives me informasjon about what kinde of datatype is rigth when I have the informasjon like thise.</modbus>

Title            ID      -1      Unit   Size   Factor   Min   Max   Default   Mode
BT1 Outdoor temp   40004   40003   °C   s16   10      0   0   0      R
EB100-BE3 Current   40079   40078   A   s32   10      0   0   0      R
Software version      43001   43000      u16   1      0   0   0      R
Freeze Protection      43013   43012      u8   1      0   0   0      R
Accumulated energy   43230   43229   kWh   u32   10      0   9999999   0   R
EB108 Version      43580   43579      u16   1      0   0   0      R
Heat curve S1      47007   47006      s8   1      0   15   9      R/W

Codesys <modbus master="" configurator=""> gives me these to pick from BOOL, BYTE, WORD, DWORD, SINT, INT, DINT, USINT, UINT, UDINT, REAL and STRING.</modbus>
