variables can perform the same math functions as floats and integers.
Strings can be combined or used to combine strings and numbers. Refer
to the %m macro command for full details about the various string
functions.
The only configuration for string variables is defining the maximum number
of characters at P689. Although you can allocate up to 63 characters for a
single string, it is best to limit the maximum size to conserve memory,
especially when using a string as a column in a database.

NTERING TRING
To manually enter a value, access the desired variable as described in the
Accessing Variables section on page 7-5, key in the desired value and
press [ENTER]. Numeric characters can be entered through the numeric
keys on the front keypad. Alpha characters and other ASCII symbols can
be entered via the cursor (arrow) keys on the front panel as described in
the Key In Value Parameters section. Press [CLR] to clear all characters
in the string.
In applications where alphanumeric entries will be common, the alpha
keyboard option or the alphanumeric serial keyboard converter kit should
be installed to simplify the entry process.

ISPLAYING TRING
When displaying string variables, the 2X5 character section of the VFD is
used to identify both the variable number and its value while the 7-
segment section remains blank. The top five character positions represent
the first five characters of the stored value. The bottom five characters
are used to display the variable name. If a string contains more than 5
characters, you can use the right and left cursor (arrow) keys to scroll
forward and backward through all characters of the string.

current mode of operation. In most cases, the entire 2X5 character
section of the VFD can be used to display a variable's name. Exceptions
to this are names for scale specific floats and strings where only the first
five characters of the name will be displayed. Time/date type integers will
not display a given name since the 2X5 character section is reserved for
displaying the time value. Integers configured as time-only or date-only
Time
values will keep the
section and display the given name on the lower 5 character section if the
name is 5 characters or less. If the name exceeds 5 character, the name
will occupy the entire 2X5 character section.
Regardless of how many characters can be displayed, all characters of a
variable's name will be transmitted when included in a custom transmit
table. When naming variables, keep in mind how the name will appear on
the display. Abbreviate names to 5 characters or less and include spaces
where necessary to center text or to wrap text to the next line.
