Basic Characteristics RAPID

Program execution
Example
[\MaxTime] Data type: num
The maximum amount of time [s] that program execution waits. If no function key
is depressed within this time, the program continues to execute in the error handler
unless the BreakFlag is used (see below). The constant ERR_TP_MAXTIME can
be used to test whether or not the maximum time has elapsed.
[\DIBreak] (Digital Input Break) Data type: signaldi
The digital signal that may interrupt the operator dialog. If no function key is
depressed when the signal is set to 1 (or is already 1), the program continues to
execute in the error handler, unless the BreakFlag is used (see below). The constant
ERR_TP_DIBREAK can be used to test whether or not this has occurred.
[\BreakFlag] Data type: errnum
A variable that will hold the error code if maxtime or dibreak is used. If this
optional variable is omitted, the error handler will be executed. The constants
ERR_TP_MAXTIME and ERR_TP_ DIBREAK can be used to select the reason.
The information text is always written on a new line. If the display is full of text, this
body of text is moved up one line first. Strings longer than the width of the teach pendant
(40 characters) are split into two lines.
Prompts are written above the appropriate function keys. Keys without prompts are
deactivated.
Program execution waits until one of the activated function keys is depressed.
VAR errnum errvar;
...
TPReadFK reg1, "Go to service position?", "", "", "", "Yes", "No" \MaxTime:= 600
\DIBreak:= di5\BreakFlag:= errvar;
IF reg1 = 4 or OR errvar = ERR_TP_DIBREAK THEN
MoveL service, v500, fine, tool1;
Stop;
END IF
IF errvar = ERR_TP_MAXTIME EXIT;
The robot is moved to the service position if the forth function key ("Yes") is
pressed, or if the input 5 is activated. If no answer is given within 10 minutes, the
execution is terminated.
