Differences from default loop

Number of loop passes

Default loops usually have a fixed number of loop passes. Real-time loops are endless running loops that are terminated by the variable V.RTG.LOOP.ENABLED. They have no fixed number of loop passes.

Motion stop

With default loops with synchronous variables (e.g. V.E. variable) as loop condition, there is always a motion stop at the loop transition since the current value of the variable must first be determined in the channel. Real-time loops do not have a motion stop at the loop transition, although the condition is evaluated in real time.

Number of loop passes backward direction

A default loop can only be move backward as many times as it previously moved forward. A real-time loop can move backward immediately any number of times until the loop is terminated by the variable V.RTG.LOOP.ENABLED.
