Addressing of communications function code parameter group and index number within the
group
The communication function code address of the frequency converter is in
strict correspondence with the function code. It consists of parameter group
and index number of parameters within the group. Reading and writing func‐
tion codes are possible through reading and writing contents of function code
address of PROFIBUS communication.
According to the data format defined in 'Request data frame in PKW area'
and 'Response data frame in PKW area', a complete communication function
code address consists of two parts: parameter group and index number of
function code within the group.
The parameter group is defined as in the table below:
Parameter group b0 b1 S0 S1 S2 S3 E0
Mapping address 00H 01H 02H 03H 04H 05H 06H
Parameter group E1 E2 E3 E4 E5 H0 –
Mapping address 07H 08H 09H 0AH 0BH 0CH –
Tab. 12-47: Addressing range of parameter group
The index number of the function code within the parameter group is defined
as in the table below:
Function code index number within the parameter group xx.00 xx.01 ... xx.99
Mapping address 00H 01H ... 63H
Tab. 12-48: Addressing range of function code index number within the parameter
group
xx means a certain parameter group among b0, b1, S0, S1, S2, S3, E0, E1,
E2, E3, E4, E5, and H0.
The function code index number within a parameter group is from 00...99
which is corresponding to the function code in the parameter list.
Use the respective mapping addresses of 'Parameter group' and
'Function code index number within the parameter group' to set a
communication function code in PROFIBUS communication.
