Hi Paf, In the mentioned thread there is one example, also when installed the master modbus software there are some examples. In the handbook that is also installed the function codes are mentioned and described There you can see also the lengths of the data. Normally you use a send to write registers or coils to the slave(s) and also a send to read some registers or coils from a slave. The information is coming back with the receive. |
