(c) Process after completion of comparison at end point
1) When repeatedly comparing from the 1st point
Set the following after setting all continuous comparison point settings for the
17th point and later.
• Continuous comparison No.1 point n setting (Un\G54 to 85) of
(Continuous comparison No.1 point monitor during comparison (Un\G86)
-1) = Continuous comparison point setting of the 1st point and later
Figure 5.7 is the example when comparing with 19 points.

2) When stopping the continuous comparison
Turn from ON to OFF the continuous comparison No.1 execution command
(Y09) under the following condition.
• (Continuous comparison No.1 point monitor during comparison (Un\G86)
-1) = Comparison end point
Figure 5.8 is the example when comparing with 19 points.

*1 When the present value may coincide with the comparison point of the
(comparison end point + 1) before stopping the continuous comparison, store
a value which does not perform a coincidence output (for example: -1) to the
(comparison end point + 1) before completing the coincidence detection at
the comparison end point.
*2 In the case of the comparison end point is 16, turn from ON to OFF the
execution command when the point monitor changes to 1.
