Addressing of Communications Function Code Parameter Group Number 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 function code
group No. and index of parameters within the group. Reading and writing
function codes are possible through reading and writing contents of function
code address of PROFIBUS communication. Reading and writing property as
well as value taking range for the function code should follow the User Man‐
ual for the frequency converter.
A complete communication function code address of frequency converter
consists of 19 bits, where high 11 bit is communication function code group
No., and low 18 bit is index of parameters within the group. Index of parame‐
ters within the group for a certain function code refers to sexadecimal expres‐
sion group No. of such function code. For example, if it is function code [E03]
(programmable skip frequency range), it is numbered as 3 in Group E. So its
index of parameters within the group is 0×03. As high 3 bit of 11 bit function
code (bit10-8 of ID) must be 000B, in order to describe it in sexadecimal sys‐
tem, function code group No. stated in this manual only refers to its low 8bit
(i.e., bit7-10 of ID). For example, if it is function code [E03] (programmable
skip frequency range), its function code group No. is 0×01. The function code
group No. mentioned above is the same as this number. Addressing the
range for PROFIBUS adapter communication function code group No. and in‐
dex of parameter within the group is shown in fig. 12-55 "Addressing range of
funciton code group and index serial No. withing the group" on page 207 .
