Running a Program
Chapter 7
7-12
When using the N search, O search, or STRING search features, first
key in the N number, O number, or character string to search for.
After it has been keyed in, press the
[TRANSMIT] key to start the
search.
If you want to: Press this softkey:
search for the entered value in the forward or reverse
direction {FORWRD} or
{REVRSE}
return to the top of the program (the beginning of the first
block) {TOP OF PRGRAM}
indicate that the desired block is found {EXIT}
The selected block is the next block for automatic execution.
If no number is keyed in for an N or O search, the control simply
searches for the next N or O word in the program.
When you press the {NEXT PRGRAM} softkey, the control first
searches for a valid program end code (see setting communications,
page 9-1). After it finds the program end code, it advances to the
program start code of the next program. If the current program is the
last program on the tape, the message “SERIAL
COMMUNICATION ERROR #5” appears on the screen indicating a
time-out error.
Important: If performing a STRING search, program execution begins at
the beginning of the block that contains the desired character string. This
is not necessarily the location of the string in the program block.
ATTENTION: It may be necessary to position the grinding
wheel at a location that allows this block to execute without
damaging the workpiece or grinding wheel. This can be done
through a manual operation or through MDI.
