I/O Messaging
The BridgeWay allows an EtherNet/IP scanner access to the I/O data of
DeviceNet slaves. The data produced by the DeviceNet slaves is collected in the
Input Table (IN) of the BridgeWay and becomes the EtherNet/IP Input I/O to the
EtherNet/IP scanner. EtherNet/IP Output data from the scanner is stored in the
BridgeWay’s Output Table (OUT) and sent to the DeviceNet slaves which con-
sumes it.
