Message frame structure
The configuration of the PROFIBUS message frame for a DP s lave S120 must
observe the following framework conditions:
S The process data of the axes or drive objects: ”Drives” must be available
before the process data of all other drive objects (Control Unit, infeed, etc.).
Note
Currently, no message frames must be configured for the Control Unit and
infeed of a drive unit. Error acknowledgement and release are performed in the
STARTER by means of free message frame configuration with BICO.
S The s tructure of the process data for the PROFIBUS message frame config-
ured in HW Config (object sequence and message frame type) must be
identical to the structure configured in STARTER.
