ABB FPBA-01 PROFIBUS DP - Example 4: Writing a Profidrive Parameter (Word)

Communication protocol 147
Example 4: Writing a PROFIdrive parameter (word)
In this example, current parameter settings are saved to the
FLASH memory of the drive. This is done by setting the value of
PROFIdrive parameter 971 (3CBh) to 1.
Note that the drive always observes the Control word (CW)
and reference (REF) bytes. The values shown below are
examples.
