Explanation of the Blocks
2.1
FB11 "CtrlUnit_FB"
The FB coordinates the cyclic process data transfer between the PLC and the
Control Unit (CU_S) of the SINAMICS S120 on the basis of the extended
SIEMENS frame 390. This requires the drive (STARTER) as well as the controller
(STEP 7, HW Config) to be configured with the SIEMENS frame 390 that was
extended by the alarm and error code.
With the extended SIEMENS frame 390 the following data is exchanged:

Details on the frame contents can be found in the SINAMICS S120/S150 list
manual in chap. 2.3 (/7/).
The FB11 uses the system functions SFC14 and SFC15.
With regard to the control unit you can do the following with FB11 ...
acknowledge errors
detect pending alarms and errors,
signal group alarms and group errors,
read/write access to DO/DI of the CU.
You can therefore use the FB 11 as interface to SINAMICS G120 in your own
applications. You should call it cyclically in OB1.
