Analog Diagnostics
Analog inputs use a 20 bit A/D converter, just like the HPAD. In the Input section, you
can see
•
The counts, directly from the A/D converter. For a 4-20 mA or 2-10V input, the value
should stay between approximately 200,000 and 1,000,000.
•
The percentage of full scale of the analog input.
•
The calculated engineering value based on the scaling.
Digital Diagnostics
The screen offers two views of all digital input and outputs. The mapping view displays
mapping, qualifiers and status of all physical outputs and all logical inputs. The List View
displays either all logical I/O points or all physical I/O points. For more information see
Digital I/O Mapping on page 34.
Mapping view
Physical Outputs and Logical Inputs, Mapping View
The button between the up and down arrows toggles between Outputs and Inputs. Use
the up and down arrow buttons to page the digital I/O points. This screen displays the
current mapping, properties and status for the logical inputs and physical outputs.
NOTE
:
You can only see used (mapped) logical outputs and physical inputs in this view. To see
all logical outputs and physical inputs, push the
Display List
button. This will take you to
the List View.
There are seven columns in the mapping view:
ST
(Status)
Current state of I/O point. - OFF - ON
Physical
Name of physical I/O point
Logical
Name of logical I/O point
IV
(Inversion)
1 - Physical I/O point is inverted.
FW
(Qualifiers)
F – Logical I/O point generates a Fault when on. W – Logical I/O point
generates a Warning when on.
FC
(Forcing)
0 – Physical I/O point Forced Off. 1 – Physical I/O point Forced On.
