4. Next add a New Module under the Generic EtherNet Bridge and add a
CIP-Connection. Here the parameters for the I/O connection are
specified. The input and output sizes need to match the input and output
sizes configured in PCB. The Address field value represents the
connection number in PCB. By default all of the connections have 248
Input words, 248 Output words, and 0 Configuration words. The Comm
format should be set to Data type INT, and the Assembly instances
should be "1" for input, "2" for output, and "4" for configuration.
5. A CIP Connection will need to be added and configured for each I/O
connection.
Configuring EIP Class 1 Connections in PCB
There are four configurable parameters for each I/O connection in PCB.
