Hi All,  
I Manage ot get my modbus application working and all is well.  
I keep on having a look at the settings on the Modbus-Flex-Server node and I realised that I don't have a clue what they actually properly mean. I had a look at documentation but found no explanation.  
Apart from bind address and port we have:

Coils - I presume number of coils, but this is coils and contacts?

same with registers, are these inputs and holding registers?

then we have min address which is fine, but what is the split-address?

Thank you.

Kind Regards  
Enginebeat
