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 ControlLogix applica-

tion sees byte 4 as the beginning of the output assembly.

The output size must be set to 4 bytes less than the actual assembly size to account

for the Run/Idle header that is automatically added by the controller.

The maximum connection size that ControlLogix allows is 500 bytes. Hence the

total 508 bytes of the input and output areas cannot be accessed when using Con-

trolLogix.
