OUTPUT ASSEMBLY (CONTROLNET)
The following parameters are used in the output assembly of the module.
Parameter
Datatype Description
General Control
DINT
Bit 0 - Inhibit Routing
MappedData
SINT[]
The data that is mapped to PLC5 file N9 and F10 when operating
as a PCCC Client or by the Internal Mapping. Can be up to 400
bytes.

CONTROLNET ORIGINATOR
The ControlNet Router module can operate as a ControlNet originator. In this mode the
module can exchange data from the Ethernet network with ControlNet devices using either
the input and output assemblies of the Scheduled ControlNet connection to the device or
using an explicit (unscheduled UCMM) ControlNet message to read or write data.

ONNECTIONS
In the example below, the ControlNet Router is owned by a Logix controller over EtherNet/IP
while the ControlNet Router is owning some ControlNet IO. The data from the Logix controller
is exchanged with the ControlNet IO.
Once the ControlNet Scheduled connections are setup and established then any Internal Map
copying to a ControlNet IO device will be written to the output assembly of selected
ControlNet device (Originator to Target). In the Internal Map the user will specify which device
instance is the target and at what offset the data must be written in the output assembly.
