ETS6 wiser LSS100100

[jdsilvapereira]

HI, 

It's possible to add LSS100100 as device of ETS6 project ? 

I have some MODBUS devices mapped in my LSS100100 (Virtual or Physical map) 

How I can add the value of 2/2/4 (virtual or physical modbus temperature) to my ETS project and use as value to send for my KNX display 1/1/6 ? 

It's possible ?

Hi!
there is no application program for the LSS100100 and therefore, you cannot add it to your ETS project.
If you have a simple KNX topology (1 line) what you have to do is manually create that group address and assign it to your display.
If you have a complex topology (multiple lines with line couplers) what you have to do is add in your project a virtual device called "Dummy" in the phisical position where your LSS100100 is installed.
Then, as before, manually create that 2/4/4 group address and assign it to both devices, your display and the dummy.
Doing like that, ETS will automatically create the necessary filter tables in the several line couplers.
Last action, download the modified configuration into the display an d line couplers

Hi, 
Now the problem is Other.
I receive the value on the KNX BUS but :
1- if the value is inserted by hand (on modbus tcp value) on LSS100100 .. the devices actuate!
2- if the values came from modbus line automaticaly, the devices dont react.

Any Idea ?

What do you mean by "values came from modbus line automaticaly" ?

Modbus is not sending automatically, it's a polling protocol between master and slaves, the master is always initiate the communication, so i guess you want the controller to act as a slave instead as master.

We have scripts to set the controller as Modbus slave (as default it's a master device), but how do you connect the device? RTU or TCP?

When using the controller on RTU you can only be master OR slave on the RTU line otherwise you have a port conflict.

Over TCP you can set the controller as Modbus slave and master, you will need to create a script with the mapping between the KNX objects and the "virtual" Modbus registers that can be read/write to from another Modbus master in your network.

Hi Erwin, 

I’m using LSS100100 as modbus tcp sniffer , that pick the values from modbus tcp devices and write the valise on the knx bus line . But if I set manualy the value the knx devices actuate , if the lss100100 publish de values , they are correct on the bus but devices ignore the value

How are things setup? Do you have a template that reads your Modbus TCP devices / registers and those are mapped to the KNX objects in the profile? Or do you use script? And you want the value to be written to Modbus when a KNX value mapped to the register is changing?

After connecting to Joao we saw that mapping the profile directly to real adreses made repeats on phisical bus.

If profile is mapped to a virtual address and then written to a phisical using a script only 2 repeats apears.

The problem is just when writting values to modbus, not for reading... Is like exists some incompatibility while writing to knx bus and modbus at same time.

Problem is parcially solved, but it would be interesting to repeat writing with other modbus devices.

Can you share the profile?
