2.2 FB12 "LineModule_FB"
The FB coordinates the cyclic process data transfer between the PLC and the Line
Module (A_INF) of the SINAMICS S120 on the basis of the extended SIEMENS
frame 370. This requires the drive (STARTER) as well as the controller (STEP 7,
HW Config) to be configured with the SIEMENS frame 370 that was extended by
the alarm and error code.
With the extended SIEMENS frame 370 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 FB12 uses the system functions SFC14 and SFC15.
With regard to the line module you can do the following with FB12 ...
switch it on and off,
request the status (ready for switch-on, in operation, PLC control requested),
acknowledge errors
detect pending alarms and errors.
