Function Block Fb51 (Schematic Diagrams) 6 - 7 - Siemens SIMATIC S5 Manual

To be able to read a data record from the positioning module, the following parameters must be
specified for the function block:
Mode (BA), source (Q-DB) and destination parameters (Z-DB, ZANF)
Parameters not required are assigned KF+O.
Example:
Parameter assignment to read machine data (I P247->PC):
- Mode BA:
- Source DB Q-DB:
- Source start QANF :
- Dest, DB Z-DB:
- Dest. start ZANF:
The machine data DB (DB1 O) on the positioning module IP247 is stored as machine data DB

The function block FB51 shows the use of the function block FB165 with direct parameter assign-
ment via the block parameters. FBI 65 must be called once for all required modes.
DB167 from DWOtoDW14 is used as the axis data block.
