Function Block Diagram
All instructions are implemented using blocks, which are connected with one another with hori
-
zontal and vertical connecting elements. There are no power bars.
In addition to the normal input and output parameters, some blocks also have a Boolean input
(EN = ENable) and output (ENO = ENable Out). The status of the input always corresponds to
the output status.
