SIMATIC VPU200/565 Programming Manual
The language used for subroutines and programs is the same. This language
is highly specific—as opposed to a more general language such as BASIC or
FORTRAN. Each line of a program or subroutine is composed of the
following elements:
A line number (which is automatically assigned by the system)
A command
Variables and operators
These items are discussed in the following paragraphs in terms of VPU200
entry. For a more detailed discussion, please see the SIMATIC 565
Programming Instructions Manual.
The Special Function commands give instructions for certain operations to
be performed. The following table lists the commands in alphabetic order
