On the XRC due to age, there is not an easy way to do this. The time amount would be over 60 seconds. How much over depends on where the cursor is at the 60 second mark. The robot job is sequential, do this, then this, then this. If the cursor was 1 line above the cursor at the 60 second mark then the JUMP would be false and bail out at 60 seconds and a hundredth or so. If the cursor was at the *LABEL then at the time would be 60 seconds plus how ever long the instructions took to execute down to the JUMP.
Probably the only true way to make this work repeatably very close to 60 seconds is with the INTERRUPT job option and possibly the CONCURRENT job option.
The way you have it written is close. The PULSE would need to be above the *LABEL. The JUMP would be IF OT#( )=OFF.
