What is a port block?
A port block is a signal interface to a fieldbus. Input/output ports represent the input and
output process data of the fieldbus.
Port blocks LP_CanIn/LP_CanOut: Signal interface to the CAN bus
Port blocks LP_MciIn/LP_MciOut: Signal interface to a plugged fieldbus module
If, for instance, the controller is to be controlled via CAN bus or a fieldbus module, the
input/output ports are connected to the application block (device-internal signal
processing) in the I/O level of the FB Editor.
[15-4] Example: Input port "LP_CanIn1" and output port "LP_CanOut1"

What is an application block?
The application/technology function set in
C00005
is shown as application block in the I/O
level of the FB Editor.
The application block comprises the signal flow processing generated via function block
interconnection for the selected application in each case (e.g. "actuating drive speed" or
"switch-off positioning"). The function block interconnection is shown in detail on the
application level.
Tip!
Every application block features so-called "free inputs and outputs" which you can
use to transfer signals from the I/O level to the application level and vice versa.
• In the Lenze setting, these connectors are hidden in the function block editor.
• These connections can be shown via the
Connector visibilities
command in the
Context menu
of the application block.
