7 years ago As stated in the README.md the output node takes an offset to write the content of the buffer to, if it is bigger than one register/coil it will continue to the next one.
No idea about the first bit, there is no where near enough information to work out what's wrong

7 years ago I solved the value type, as it appears it needs to have a property like in the example above
I am trying to use the write serial Modbus, however I am having some difficulties. Tried the binary module mentioned in the readme text and have configured it as l32f (little endian 32 bit float) so when I try to inject a number of 140000 it brings back an error saying that error: invalid input.
Also there is only the option to write to one register, however if I use the buffer from above it will need to use two, is this done automatically when using the right buffer size?
