The specified formatted data output group receives the current value of
the Output Data expression as a 16-bit binary or 7-digit BCD value along
with a decimal point position and sign bit. The Allen-Bradley PanelView
Intelligent Operator Panel automatically handles these formats for
displaying values.
The Numeric Format menu combination selections are explained below.
Auto Binary Numeric Format
Select Auto from the first numeric format menu and Binary from the
second menu to write the 16-bit binary value (magnitude only, not 2s
complement) of the output data expression to the lower numbered I/O
group defined for the selected formatted data output group.
The number of digits to the right of the decimal point (automatically
determined by the motion controller to maintain the maximum number of
significant digits in the displayed value) and the sign of the value are
written to the four highest bits in the next higher numbered I/O group.
The actual number of decimal digits changes from update to update as the
value of the output data expression changes.
To continuously send the actual position of Axis 0 to a PLC-5 using a
previously defined formatted data output group (Axis_0_Position), enter
Actual_Position_AXIS0 in the Output Data field and select
Axis_0_Position from the RIO Formatted Output List.
