Internal Mapping from ControlNet to IDS
The ControlNet Router then uses the data from the ControlNet Output assembly (which was
copied to IDS offset 4080) to execute a Set Single Attribute to a target EtherNet/IP device
using explicit messaging.

Set Function from IDS to EtherNet/IP device
In the next example below, the ControlNet Router is receiving data from an EtherNet/IP
device using a Get Explicit EtherNet/IP message and saving the data at IDS offset 4040.

Get Function from EtherNet/IP device to IDS
The ControlNet Router will then map the received data at IDS offset 4040 to the ControlNet
