By clicking on ETHERNET-MODULE MW100 within the Controller Organizer tree, the
connection can be fully configured. Of note is the IP Address which should point to a
MW100, Comm Format which defines what data types to use (MW100 supports only
DINT type), and Connection Parameters which will layout the inputs and outputs of the
MW100. In this case the connection is configured to communicate using double precision
integers to an MW100 at IP address 10.0.232.126 with inputs at Assembly Instance
130 (corresponding to Communication Channel C001-C010; 10 Channels due to Size),
and outputs at Assembly Instance 131 (corresponding to Communication Channel
C101-C110; 10 Channels due to Size). The Size of the Input and Output Assembly
Instance can range from 1 to 100 to encompass 100 Communication or MATH channels
in a block and 60 for I/O Channels. When using I/O Messaging, there is a limit of 100
inputs and 100 outputs per MW100 (Explicit Messaging must be used to reach more
MW100 channels). Note, a limit of 125 32-bit points per instance is the maximum data
size that EIP allows for I/O Messaging.

The following diagram depicts the available Instance IDs, Sizes, and Data Types that can
be configured within a connection.
