the particular object selected, when changed during programming. This option
has no effect on operation of the button during online or simulation.
O- Task(s): this option is for button-type objects (i.e. Multi-Task Single-State button) that
can be configured for more than one task. If the Task is grayed out, this means that the
object can do only that one defined task.
A task is some action(s) that the button is programmed to do (see Chapter 6 – Task
Management for more information). Click to locate display the Touch Screen Task
List dialog box to add/modify the tasks.
P- Value or Data Properties: this section configures how the selected object interprets (i.e.
signed/unsigned, leading zeroes, ranges, etc.) the number it is to display or write.
a. Value Data Type: options vary according to the tag address selected (bit, 1 byte,
2 bytes, or 4 bytes). Options are unsigned, signed, hexadecimal, BCD, binary,
Float, ASCII, or ASCII Numeric.
i. Unsigned  represents number in target address as an unsigned decimal
number.
ii. Signed  represents a signed decimal number. Range is  -
2,147,483,648 to 2,147,483,647 for 4-byte registers, -32768 to 32767
for 2-byte, and -128 to 127 for 1-byte.
iii. Hexadecimal  represents a hexadecimal (base 16) number. Range is 
0 to FFFFFFFF for 4-byte registers, 0 to FFFF for 2-byte, and 0 to FF for 1-
byte.
iv. BCD  represents as a BCD (binary coded decimal) number. Range is  0
to 99999999 for 4-byte registers, 0 to 9999 for 2-byte, and 0 to 99 for 1-
byte.
v. Binary  represents as a binary (base 2) number. Range is limited to 16
bits (LSW) for 4-byte registers, 16 bits for 2-byte, and 8 bits for 1-byte.
vi. Float  represents a floating-point number using the IEEE 754 single
precision format. Any number with no more than nine digits can be
displayed. If necessary, the number is rounded. Only supported with a
4-byte register tag address.
vii. ASCII  represents the data in a 16 bit number as two ASCII printable
characters. Hex values 0-9 display as numbers 0-9, 0A-1F is displayed as
small case decimal numbers, 20-FF is shown as printable ASCII
characters. The HMC reads consecutive registers according to the
Length field (ex: if Length=10, then HMC will read five consecutive
registers, starting with the designated Tag Address.
viii. ASCII Numbers - same as ASCII (see above) except that all non-printable
values display as zeroes.
b. Display Leading Zeroes: when enabled, data is presented with leading zeroes to
the left of the value, if required to fill in the number of digits specified.

is for security password entry.
d. Keypad (for data entry objects): enable or disable popup keypad input. Note: if
popup keypad input is disabled, entry is still available if a static keypad is placed
onto the same screen as this object or on a popup screen. For more information
on how to do this, see On Screen Keypads later in this chapter.
i. Screen Name: determines which popup keypad is used.
