4. Multi Drop Serial Link Parameters
The different parameters available on ModBus network are listed in table.
The description of different columns as below:
Sr. No. – It shows the modbus register address corresponding to the variable. All read and write
queries are made using parameter number.
Parameter Name – It shows the name of parameter corresponding to register address. It gives an
idea about use of the parameter in application.
R/W – It gives information of accessing the parameter. R means the parameter is read only. W means
the parameter is writing only. If R/W is written then the corresponding parameter has full access for
read and write.
R Read Only
W Write Only
R/W Read and Write
Unit – It shows the corresponding unit for the parameter. If the unit is not listed then the parameter
may be gain or constant.
Default – It shows the default value of parameter.
Min – It shows the minimum value of the parameter. Any attempt to write the value less then minimum
value is not allowed. Blank cell means minimum value of parameter is 0.
Max – It shows the maximum value of the parameter. Any attempt to write the value more then
maximum value is not allowed. Blank cell means maximum value of parameter is 65535.
Resolution – It gives the information about the resolution for the corresponding parameter. For
example any parameter has resolution 1 digit after decimal point then if user want to write 2.5 then
first multiply it by 10 and then send it as 25. Similarly 25 received as read then divide it by 10 so the
last result is 2.5.
Please consider following points Regarding Resolution:
decimal Point
1 Received Value/10 Send Value * 10
2 Received Value/100 Send Value * 100
3 Received Value/1000 Send Value * 1000
4 Received Value/10000 Send Value * 10000
Please treat negative values in 2’s complement form.
