Arithmetic Parameters and Program Jumps

10.2 Unconditional program jumps

Axis U: Pallet storage, transporting the pallet to the working area

Axis V: Transfer line to a measuring station, where sampling controls are carried out:

N20 GOTOF LABEL_0

N40 LABEL_1: R1=R2+R3

N60 LABEL_0:

N80 GOTOB LABEL_1

Jump destinations with user-defined names can be programmed in a routine. The command

GOTOF or GOTOB can be used to branch to a jump destination from any other point within

the same program. The program then resumes execution at the instruction immediately

following the jump destination.

Destination not found

If the destination is not found, program execution is terminated with Alarm 14080

"Destination not found". Command GOTOC suppresses this alarm. Program execution is

resumed at the line following the GOTOC command.

Destination backward

Jump with label

Label_1: ;destination

GOTOB Label_1

Jump forward

Jump with block number

N100 ;destination

;Jump forward to LABEL_0

;Branch destination LABEL_1

;Branch destination LABEL_0

;Jump backwards to LABEL_1
