Overview
The short docu on hand describes the blocks which can be used for connecting a
PROFINET/PROFIBUS of a SINAMICS G120 to a failsafe SIMATIC S7300/400F in
STEP 7 V5. This short docu does not give any explanations and only shows the
most important points for integrating the blocks into your own projects.
The following functions can be realized with this:

Explanation
The FB performs the communication
between the PLC and the Control Unit drive
object of the S120. Its digital inputs/outputs
are read/controlled, errors and alarms are
transmitted and errors acknowledged.
The FB uses the system functions SFC14
and SFC15 and uses the SIEMENS frame
390 with frame expansion (alarm, error) for
data transmission.
The FB performs the communication
between the PLC and the line module drive
object of the S120. The module is switched
on/off with FB12, the mode is read out,
errors and alarms are transmitted and
errors are acknowledged. The FB uses the
system functions SFC14 and SFC15 uses
the SIEMENS frame 370 with frame
expansion (alarm, error) for data
transmission.
The FB performs the communication
between the PLC and the "Drive" drive
object of the S120. With FB12 status and
control word are exchanged and speed
setpoint and actual value are transmitted.
Errors and alarms are furthermore
transmitted and errors are acknowledged.
The FB used the system functions SFC14
and SFC15, and uses the default frame 1
for the data transmission with frame
expansion (alarm, error).
FB is only used as jump table for FB11,
FB12 and FB13. In addition it provides the
information for WinCC flexible whether the
created drive object (Line Module and Drive
1-6) has been configured.
With this FB the PLC can have read and
write access to selected parameters in one
of the drive objects.
The two parameters of each of the
configured drive object are given read and
write access with the job DB of the
application example and the fault memory is
read out.
