Is there a way to add the Modbus add the addresses to my Modbus device using the sys.device.addDevice? I successfully added a Modbus device using the module, but now I want to add the device addresses to the device. I don’t see a way to do that.

Did you figure how to add the addresses to your modbus device ?

I’m also interested in creating and defining new devices by scripts.

You don’t actually need to do that to access the data in the device. Just use the [addTag](https://support.inductiveautomation.com/usermanuals/ignition/system_tag_addtag.htm) scripting function with the appropriate address. If you look at the Address Mapping section [here](https://support.inductiveautomation.com/usermanuals/ignition/addressing.htm), you can see that adding the mappings for OPC browsing is a convenience, not a requirement.

Please, give us an example.  
I need to access the Modbus devices datas (bits 0, 1, 2, 3, 4, 5, 6, 7, 8). I can’t.

You’ll have to be more specific. See the addressing guide [here](https://docs.inductiveautomation.com/display/DOC79/Modbus+Addressing). Note that the modbus protocol doesn’t have any functions for accessing individual bits of 16-bit registers. You’ll have to read the entire register and extract the bits you want with boolean operations or the [getBit() expression function](https://docs.inductiveautomation.com/display/DOC79/getBit), and merge booleans into integers to write back. See [binEnc()](https://docs.inductiveautomation.com/display/DOC79/binEnc) for that.
