ControlNet Diagnostics File Layout
When you specify a Control Diagnostic File in RSNetWorx for the
ControlNet network, the PLC-520C, -5/40C, -5/46C or -5/80C
processor copies the 40 words of diagnostic counters into the
specified integer file.
Twenty-three additional diagnostic counters are available in the
ControlNet diagnostic file. To access these counters, you must first
use RSLogix5 to increase the size of the ControlNet diagnostic
integer file to 63 words.
The layout of the ControlNet diagnostic file is described in the
following table. The processor updates this file once every second.
