Rockwell Automation 2711E-ND1 PanelBuilder 1400E Reference Manual - Manual (Page 83)

76 Numerics
Publication 2711E-820 – January 1998
The control you assign must use an analog tag with a Floating
Point data type. If you use Device tags (for ControlNet or DH+),
the tag must specify a floating-point address in the programmable
controller. If you use RIO, the tag must be configured with a
Block Transfer File address. For more information see Chapter 6,
Defining Tags, in the PanelBuilder 1400e Configuration Software
for Windows User Manual.
Note: If you use the Implicit option, the application will be
compatible only with PanelView Version 2 or later. The
application will not be compatible with earlier versions.

Fixed Position specifies that a decimal point always appears in a
fixed position, and a fixed number of digits is always displayed
after the decimal point. You can specify the number of digits to
follow the decimal point.
The number of digits after the decimal determines the minimum
number of digits in the value to be sent to the control. For
example, if the setting was for three digits after the decimal, an
operator’s entry would appear as follows:

Note: Although you can configure up to 15 digits after the
decimal point, 10 or more digits may generate a Mistake message
on the PanelView terminal. PanelView converts the decimal
number into a signed long value, with a range of –2,147,483,648
to 2,147,483,647. If the converted number is outside this range,
the Mistake message appears.
If the setting was for 15 digits after the decimal, an operator’s
entry would appear as follows:

PLC Controlled allows the PLC to set the number of digits to be
displayed after the decimal point.
