TNC 416/TNC 406/TNC 306 Commands 3/2000
Example of the use of the SUBM command:
Dependent on Input I10 the subprogram with the Label LBL 300 is handed over to the NC for
processing. In addition, the execution of the subprogram is checked in the main program with the
RPLY command and canceled with the CAN command in conjunction with Input I11.
Line Instruction Program Comments:
1 L I10 ;Interrogate state of Input I10
2 JPF 100 ;Dependent on Input I10 skip
;Call Module
3 RPLY B 128 ;Interrogate status of the Submit program
4 <> K+0 ;Submit program already transferred to
;the NC for processing ?
5 JPT 100 ;If program already transferred to the NC,
;renewed program call skipped
6 SUBM 300 ;Call up Submit program
7 = B 128 ;Store Identifier in Byte 128
8 LBL 100 ;Jump address
9 L I 11 ;Interrogate state of Input I11
10 JPF 110 ;Dependent on Input I11, skip the deletion
;of the Submit program
11 CAN B 128 ;Interrupt execution of the Submit program
;or remove program from the queue
12 LBL 110 ;Jump address

XX EM ;End main program
XX LBL 300 ;Begin Submit program (is added as with Modules
XX • ;at the end of the main program)
XX • ;
XX • ;
XX EM ;End Submit program
In this case, the contents of the Submit program could, for example, be a display in the PLC
window, which can be done via a fixed PLC Module.
