LM5 Modbus TCP

[OysteinEl]

How do i get the LM5 to act as an modbus tcp master ?

another question i get data from the Node-Red system now but the knx will not react to it:



I see that the 'Current Value' changes and works fine when:
- Operating the light switch  KNX->LM5 
- 'Set value' function LM5->KNX

but this one does not send from LM5->KNX
- Sending true or false commandos from Node-red  Node-red->LM5->KNX

this does not send to the knx bus, the statusline above was changed from Node-red but the knx bus does not turn on or off the light.
 any ideas, no filters are applied.
