You can use 56AmxnMon to display the active drop list and the
diagnostic counters for both DCS and RIO network communication, and
diagnostic counters for the backplane communication with the
ControlLogix processor.
To troubleshoot problems with DCS data, you can use 56AmxnMon to
view the raw DCS data coming in to the module from the network for
being sent to the network.
Reading Diagnostic Counters into the ControlLogix Program
For DCS Master or Slave operation, you can map diagnostic counters
into an input data tag. Refer to page 17 for details on how to do this.
You can also use a MSG instruction to read the AutoMax diagnostic
counters into your ControlLogix program.
Use an instance level get attribute single to read data from instance 1,
attribute 0 of the DCS Data object. Refer to page 41 for information on
how to do this.
Using RSLogix 5000 to Diagnose Problems
You display the Module Properties dialog by right clicking on the
module while online with RSLogix 5000. This may help diagnosing
some problems, especially connection errors.
The following information is based on version 12.00 of RSLogix 5000.
General Tab
The Type should be 56AMXN DCSNet Interface.
The Vendor should be Allen-Bradley.
The Name is whatever you set when you configured the module.
The description is whatever you set when you configured the module.
Comm Format and Slot should match what you set when you configured
the module.
Connection Tab
The Inhibit Module checkbox inhibits the module. It should not be
checked for normal operation.
The Major Fault on Controller if Connection Fails While in Run Mode
checkbox causes the module to fault the processor if the connection
between the ControlLogix processor and the module fails.
If there are any problems connecting to the 56AMXN module, there will
be an error message in the module fault area. For example, if the
