• Checking Indicators
• Checking the I/O Unit Interface Status
Example:
The following allocations will be used for status when the default alloca-
tions are used for a Communications Unit with node number 01 connected
to a C200HX/HG/HE(-Z) DeviceNet Master Unit with unit address 0.

• The first two words of the input area is automatically allocated for the
I/O Unit interface status information. This allocation cannot be
changed.
• Words are allocated for the input/output data for each I/O Unit in the
order that the I/O Units are connected (I/O Unit interface addresses 0
to 3) in the input area (input) and the output area (output).
• The input/output areas are allocated in the words corresponding to
node numbers 01 to 11.
With normal operations, all indicators should be lit green.
