DSR Message and Response
The following description provides information on how to set DSR messages and what
details are returned as responses. Each DSR message or response is divided into 8-bit
blocks. Therefore, data must be set in 8-bit blocks for communications.
7-3-1 Data Read (Function Code: 03 Hex)
H
Settings and Responses
•
To read data (such as control I/O status data, monitor item data, or parameter set value data) from the
Inverter, issue the following DSR message.
•
Data read is a maximum of 16 words in length (i.e., data of 32 bytes from 16 registers) per DSR mes-
sage.
•
A register number is allocated to each function item, such as control I/O, monitor item, and parameter
functions. The register number of each parameter is indicated wherever the parameter is explained in
this manual and in
Section 10 List of Parameters
. For register numbers other than those of parame-
ters, refer to
7-6 Register Number Allocations in Detail
.
Note 1.
A parameter corresponds to one register (one word), so the “number of registers of read data”
indicates the number of parameters to be read (i.e., the number of consecutive registers be-
ginning with the first register number).
Note 2.
The “number of bytes of attached data” indicates the number of bytes of data read from the
registers attached from that point onwards. The number of registers must equal the number of
bytes divided by two.
