MSAC1_Write Service
The PROFIBUS DP-V1 MSAC1_Write service allows a PROFIBUS DP-V1 Master Unit to write (param-
eter) data acyclically to a PROFIBUS DP-V1 slave device, which is allocated to that Master unit.
The figures below show the command and response message formats.

 Response Format
Upon normal completion of the MSAC1_Write command service two types of response frames can
be returned:
• A normal data response frame, signalling successful completion of both the command and
the PROFIBUS service.
• A normal response frame containing PROFIBUS error codes, indicating that the PROFIBUS
service was not completed correctly, although the message was completed normally.
Both response frames are shown below.
