About the Linking Device

8 (70)

Each of the two network interfaces exchanges data on its network through two buffers. The
linking device forwards the data internally between these buffers as shown below.

Process Data I/O Buffer

Both the incoming and outgoing buffers on the EtherNet/IP side and the incoming and the
outgoing buffers on the Modbus TCP side holds a maximum of 4096 bytes of data.

The buffers in the EtherNet/IP interface are represented by up to 10 separate class 1 connections
with a maximum of 500/496 bytes assemblies.

There is one assembly in each direction per connection in this linking device.
