8. DEBUGGING FUNCTION
POINT
(1) Assume that "Step # [ 2] = <ON>" is designated as the detailed condition in
the case of the ladders shown below; In this case the monitor execution differs
for the two ladders. For (a) it is "X0 and X1 both ON" and for (b) it is "X1 ON
(regardless of ON/OFF status of X0)".
If a step part way through an AND/OR block is designated for a monitor
condition, the monitor data collection timing is such that data is collected when
the status immediately before execution of the step designated from the LD
instruction in the block becomes the designated status.
(2) If the ladder block head other than 0 step is specified to the step number as
detailed conditions, the monitor data is collected when the instruction
execution status immediately before execution is the specified status.
When "Step # [ 2] = <ON>" is specified in the ladder below, the monitor data is
collected for OUT Y10 ON.
