Figure 5-16 Overview Of The Driver Blocks With Fef Functionality - Siemens Add 7 AddFEM Manual

AddFEM
5.5.2 Additional Interfaces of the Driver Blocks for
Front End Functions (FEF)
No additional driver blocks are required for the use of the AddFEM with FEF. The
existing drivers can be changed over to the FEF functionality by means of configu-
ration. Only two data blocks for the input and output data have to be created for
the additional data exchange. The additional data blocks are used to exchange
FEF–specific input and output data which cannot be exchanged via the input and
output bars.
