The move (MOV) instruction is a placeholder to advance the stop sequence to the next step by incrementing the
StopSEQ[0] tag. Each step in the stop sequence requires a unique value be assigned in ascending order. The steps
typically increase by multiples of five or ten. By default, the stop sequence-template steps 1…10…20…30 …999.
Before moving to the next step, a predetermined condition must normally be met to make sure the current step is
complete.
By default, the stop sequence ends when the StopSEQ[0] tag value reaches 999. The StopSEQ[0] tag is then
monitored in the R02_Monitor routine of the application module for a value of 999 and then sets the
ApplicationName.Stopped tag. The machine module monitors the ApplicationName.Stopped tag to determine
when the application was properly stopped.
Figure 13 - First Stop Sequential Step Example
This CNC Work Cell first stop step example includes a latch (L) instructions, and a MOV instruction, which
indexes to the next sequence step (for example, value 10 into the StopSEQ[0] tag).
