Sequence of operation

PAGE DOWN

DELETE LIST

If more than 20 programs have to be entered, you use "PAGE DOWN" to switch over to the second page of the screen form.

"PAGE UP" is used to switch back to the first page.

The list can comprise up to 40 main program numbers (= file numbers). The "CURRENT NO" (=current number) column on the left signifies the sequence of processing in OPS. OPS always begins with the program at the current number 1.

OPS uses the program number 0000 as end criterion. As soon as this number is reached during processing the program sequence list, OPS ends automatically.

When the program number ffff is entered, this line in the list is skipped in OPS.

Application: Creating space lines in order to subsequently enter a pro- gram or subsequently delete a program number entered already.

You use the "DELETE LIST" softkey to delete all 40 program numbers (not the actual programs!) and unit numbers entered by overwriting with zeros

Program sequencing (=OPS)

OPS requires:

1)The files on the diskette which are used for the OPS must be given (e.g. by using the remote operation functions) the following structure:

-One file contains exactly one main program at the beginning of the file

-The numbers of the main program and the file, each consisting of four digits, are equal.

-The main program at the beginning of the file may be followed by an unlimited number of subroutines.

Important: A file should contain all subroutines which are called in the main program of this file.

Exception: Subroutines required by a great number of main programs, which would consequently have to be stored in a great number of files.

Suggestion: Store these programs in a protected range of numbers of the part program memory which is not deleted during OPS.

Explanation: If during OPS the next program file is retroloaded after the end of a program, the NC memory is prior to this cleared except for a reserved range of program numbers (the limits of this range can be set at the disk drive unit).
