I am trying to write some RTU code in readiness to connect to a CerboGX when I get to site. (which will have a Solar regulator and a SMART shunt attached ).
From the TCP register, on sheet 1 where all the modbus addresses are shown the address isnt a ‘full’ traditional modbus address. am I correct in thinking that signed and unsigned integers are simply given a 30,000 prefix? for example adress 771 (solar charger Battery voltage becomes 30771? if so are these the same for writable addresses as traditionally they would be 40000. for example 774 solar charger on/off. 40774?
Sorry if this is long winded, just trying to be prepared so I can set this up before I go to site
