The
DREADI1
command allows continual numeric or function key data entry from the RP240 (when used
in conjunction with the
DREAD
and/or
DREADF
commands). In this immediate mode, program execution is
not paused (waiting for data entry) when a
DREAD
or
DREADF
command is encountered.
NOTES
•
While in the Data Read Immediate Mode (
DREADI1
), data is read into
VAR
and
VARI
variables only
(e.g.,
A(DREAD)
or
V(DREAD)
substitutions are not valid).
•
This feature is not designed to be used in conjunction with the RP240's standard menus (see
Programmer's Guide for menu structure); the RUN and JOG menus will disable the
DREADI
mode.
•
After the RP240’s ENTER key is pressed (to enter numeric data), the value is displayed on the
RP240 display at the 1,30 location (showing 10 significant digits).
•
Do not assign the same variable to read numeric data and function key data—pick only one.
Simple Numeric Data Entry (example):
VAR1=25000 ; Initialize variable #1
DCLEAR0 ; Clear entire RP240 display
DWRITE"ENTER VALUE > " ; Send message to RP240 display starting at location 1,0
DREADI1 ; Enable RP240 data read immediate mode
VAR1=DREAD ; Set variable #1 (VAR1) to receive data entered on the RP240.
; Current VAR1 data will be displayed at cursor location 1,30
; (fixed). New data will be displayed at current cursor location
; as defined by the previous DCLEAR, DWRITE and DPCUR commands—
; this is the home cursor location for subsequent data entries.
L77 ; Start loop of 77 repetitions
D(VAR1) ; Set distance equal to the current (last entered) RP240 data
GO1 ; Initiate move
LN ; End loop
DREADI0 ; Exit RP240 data read immediate mode
; As the loop is running, the user may enter in a new distance value
; (which must be terminated with the ENTER key) via the RP240 numeric keypad.
; The numeric keystrokes cause the digits to be displayed on the RP240
; starting at the home cursor location (see VAR1=DREAD description in the
; example above). When the ENTER key is pressed, the variable is updated;
; the most significant 10 digits (total, including sign & decimal point
; if appropriate) of this variable are displayed at cursor location 1,30;
; and then the data entry field (starting at home) is cleared.
; The Gem6K drive is ready to accept new data.
Numeric Data & Function Key Entry (example):
VAR1=25000 ; Initialize variable #1
VAR2=1 ; Initialize variable #2
DCLEAR0 ; Clear the RP240 display
DPCUR2,0 ; Place RP240 cursor on line 2, column 0 (bottom left corner of
; display)
DWRITE" SLOW FAST" ; Send message to RP240 display starting at location 2,0
DPCUR1,0 ; Place RP240 cursor on line 1, column 0 (top left corner)
DWRITE"ENTER VALUE > " ; Send message to RP240 display starting at location 1,0
DREADI1 ; Enable RP240 data read immediate mode
VAR1=DREAD ; Set variable #1 (VAR1) to receive numeric data entered on the
; RP240's keypad
VAR2=DREADF ; Set VAR2 to receive RP240 function key input
L ; Begin loop
