NOTE:
A PREACT setting of "LEARN"
functions only when the setpoint is a
batch step.

Capital letters are preferred.
NOTE:
Setpoint names must be established
using commands entered through
the EDP port.
FRONT PANEL PREACT VALUE ACCESS
Values for the setpoint parameter PREACT can be viewed on the front
panel, while in the normal operating mode if the PREACT parameter has
been turned ON . The SET POINT key function allows you to access the
PREACT value if the ACCESS parameter is set to ON and PREACT is not
OFF.
After pressing SET POINT, you will see the "SP x" prompt where "x" is
the setpoint number. The display then shows the setpoint target value. While
viewing the "SP x" prompt or the target value, you can press the SET
POINT key again to view the preact value. The display will read
"P xxxxxx", where "xxxxxx" is the PREACT value.
The PREACT value can be up to 6 digits long and the preact value decimal
places will be truncated to fit on the indicator display.
While viewing the PREACT value you can change the value if the ACCESS
parameter is set to ON. When viewing the value, you can enter a new value
from the keypad and press the ENTER key. To clear the PREACT value,
press the 0 key and the ENTER key.
SETPOINT MNEMONICS
The setpoint mnemonics feature allows you to customize the prompts given
to the operator when the SET POINT key is used. The default prompt is
"SP x", where "x" is the setpoint number. You can define up to 10 unique
names, with up to 7 characters each. A setpoint can be assigned one of the
defined names that will appear as the display prompt when the SET POINT
key is used to access the setpoint. This assigned name can be printed on a
setpoint print ticket initiated by this setpoint.
Defining setpoint names
There are 10 user-definable names, with up to 7 characters each. You define
the names via the EDP port using the following command:
SPNAME#x=AAAAAAA
where x is the name number 0, 1, 2, 3, ... or 9 and AAAAAAA is the
assigned name. Uppercase letters are recommended for the setpoint names
because many of the lowercase letters are not legible on the 14-segment
display. Table 7-2 shows default command names for numbers 0 – 9.
