3.2.2. Acyclic data exchange
The database also offers the option of exchanging data acyclically, with one
request at a time. Drive parameters can be read and written separately and inde-
pendently of any IDB/ODB cyclical data exchange using the SDO functions. These
are typically configuration data, not process data: management in real time is not
guaranteed.
Example of how to access a read parameter:
Supposing parameters 250 "Output current" and 270 "DC link voltage" are read.
The SDO input must be set as follows:
The response contains the value of the parameter divided into 4 bytes with 32-bit
IEEE754 float, since this is a float parameter (see the drive manual for information
about the format of individual parameters).
