INTERNAL DATA SPACE MAPPING
When the module is operating as a ControlNet Target, the data from the originator device
(e.g. Logix Controller) can be mapped to the Ethernet interface using the Internal Map. The
Internal Map configuration window is opened by either double clicking on the module in the
tree or right-clicking the module and selecting
Configuration
and selecting the
Internal Map
tab.

CONTROLNET TARGET SOURCE
When copying data from a connection originator (e.g. the output assembly from the Logix
Controller) to the Ethernet interface, the source type needs to be CNet Target.

ControlNet Target Source Type
The source instance will be the connection number, which in this case is always
Connection 0
.
The Source Offset is the offset in the
Mapped Data
section of the ControlNet output assembly
from where the data must be copied. The Count is the number of
bytes
that will be copied.
The
Mapped Data
section will be available when using the provided UDT for the Output
Assembly.

CONTROLNET TARGET DESTINATION
When copying data from the Ethernet interface to the ControlNet Target input assembly, the
destination type needs to be CNet Target.
