BAcNet to KNX Data types - AlexLV - 14.10.2024
Hi,
How to select correctly KNX group data type when reading BacNet info and writing to groups for these value's types:
analog input
analog output
analog value
binary input
binary output
binary value
command
device
multi-state input
multi-state output
multi-state value
accumulator
pulse converter
integer value
large analog value
positive integer value
Some additional questions regarding BacNet Scripting:
1. how to check BacNet device status like it is done for ModBus (Device Satus Object) if communication is lost?
2. I need read info from recuperation unit (max 50 parameters), Can I do it every minute with resident script, from communication point of view (connection over IP)?
BR,
Alex

I'm guessing you are referring to bacnet client.
It is up to you what group address type is selected, check what value is received and if necessary do a conversion.
1. Every command has result and error, you can monitor error for issues. In modbus we just check if we receive valid result few times in a row, if not device offline is set.
2. It should be fine, use direct connection mode (last example)
