Notes About Using ControlLogix I/O Connections

When configuring I/O connections between a Rockwell Automation Control-

Logix EtherNet/IP scanner and the BridgeWay, the Generic EtherNet/IP device

type should be used.

The Run/Idle register is automatically inserted at the front of the output data and

the application has no control over its use. The System Run Mode bit is set

according to the Run/Program mode of the controller.

The connection output size should be set to the configured DeviceNet slave output

data size plus 4 bytes for the command register (up to a maximum of 496 bytes

inclusive). The Run/Idle header is automatically added by the controller and does

not come into play in the size. The connection input size should be set to the con-

figured DeviceNet slave input data size plus 4 bytes for the input status register

(up to a maximum of 500 bytes inclusive).

The status assembly may also be monitored by configuring the generic device

using a “with status” comm format.

The BridgeWay does not support a configuration assembly. The configuration

instance in the device configuration may be set to any number since it will be

ignored. Set the configuration assembly size to 0.
