ControlNet Diagnostics File Layout
When you specify a Control Diagnostic File in RSNetWorx for the ControlNet network, the PLC-520C, -5/40C or -5/80CC 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.
