Ethernet-to-DeviceNet Linking Device 37

Rockwell Automation Publication 1788-IN055C-EN-P - September 2011

Output Assembly

The output assembly contains a 32-bit command register followed by the data in
the linking device’s output data table.

The output data format and content is determined by the DeviceNet scanner
configuration. The data appears in the table as it is mapped to the DeviceNet
output connections. The output data in the assembly is 123 DINT long;
however, only the size of the output data table will be used. The remaining space
will be ignored.

Status Assembly

The status assembly is a collection of status and diagnostic information for the
linking device’s DeviceNet network interface. The information in the assembly is
updated once a second.

All information in the status assembly is stored in little endian format. The
least significant byte of multi-byte values is stored first.
