EtherNet/IP 6-6

Output Assembly

The output assembly contains a 32-bit command register followed by the

DeviceNet slave output data.

The DeviceNet slave output data format and content is determined by the

DeviceNet scanner configuration. The DeviceNet slave data appears in the table

as it is mapped to the DeviceNet output connections. The DeviceNet slave output

data in the assembly is 492 bytes long; however, only the size configured for the

output data will be used, the remaining space will be ignored.

Note: EtherNet/IP I/O connections append a 32-bit Run/Idle register at the front

of the output data. The actual output data transferred in the I/O connection

includes this extra 4 bytes at the front of the output assembly described above.

The Command register is a bit string with the following bit definitions.

Bit Description

0 Local Run Mode. Used in conjunction with the Sys-

tem Run Mode bit in the Run/Idle register to deter-

mine the run mode of the BridgeWay. Both bits must

be set for the BridgeWay to be in Run mode; other-

wise the module will be in Idle mode.

1 Fault. Sets a fault condition in the BridgeWay.

2 Disable DeviceNet network.

3 Not used.

4 Reset the BridgeWay module.
