POINT
1 . If a step between the AND/OR blocks is specified as a monitor condition,
monitor data is sampled when the status previous to execution of the
specified step is specified by the LD instruction. The monitor timing depends
on the step specified as a monitor condition. The following shows examples of
monitoring when the Step 2 is ON (Step No. [ 2] = <ON>).
• When the Step 2 is connected by the AND instruction:
In Figure 6.29, the monitor execution condition is established when both
"X0" and "X1" are ON.
• When the step 2 is connected in the middle of the AND/OR block
The monitor execution condition is established when "X1" turns ON in
Figure 6.30. (The ON/OFF status of "X0" does not affect the
establishment of the monitor execution condition.)
• If the beginning of a ladder block not at Step 0 is specified in Step No. as
a detailed condition, monitor data is collected when the execution status
of the instruction immediately before execution becomes the specified
status. If (Step No. [ 2] = <ON>) is specified in the following ladder,
monitor data is collected when OUT Y10 turns ON.
2 . Be sure to set the condition of the step set as step No.0 to "Always".
