Block identification
Before you can integrate the safety-relevant function block
"F_DRIVE" into the existing program structures, you may have
to change the block number resp. the symbolic name.
In order to unambiguously identify the blocks, the block
header and the block version of the relevant function block
have been designed as an input block.
This input block is always the second input block (after "EN").
The input name is composed as follows:
• "_Header_FB-NAME_FB-Version"
Input name of the function block "F_DRIVE"
Block identification
The input block used for identifying the block has no functional
significance and is therefore connected to VKE0.

Information on the formal operands
The names used for the individual formal operands of block
"F_DRIVE" are derived from English terms. In order to achieve
a better understanding, the related English term is added in
square brackets when using a formal operand for the first time
(refer to the Chapter Description of functions).
Example:

The operands are described in detail in the FBD / LADDER editor
using a hint.
