Using Peer-to-Peer
Communications To have your adapter receive data from or transmit data to another
2100-GK61, 1203-GU6, or 1336-GM6 on the DeviceNet network,
you must configure it for peer-to-peer communications. Peer-to-peer
communications are best used in the following instances:
• A PLC sends data to a drive. That drive re-transmits the data to
other drives on the network.
• A drive is configured on a network. It sends data to other drives
on the network.
Important: After setting up peer-to-peer communications, you must
make sure the configuration that you set up works as you intend it to
work.
