(b) When only a device is specified
Either word device or bit device can be specified.
• When a word device is specified
Monitor data is collected when the current value of the specified word device becomes the specified value.
Enter the current value (in decimal or hexadecimal).
• When a bit device is specified
Monitor data is collected when the execution status of the specified bit device becomes the specified
status. Select the execution condition (on the rising edge or falling edge).
(c) When a step number and device are specified
Monitor data is collected when the status previous to execution of the specified status or the status (current
value) of the specified bit device (word device) becomes the specified value.
● When "Step No.[100]=<>, Word device [D1]=[K5]" is specified as an execution condition, a monitor execution condition
is established on the rising edge of the step 100 and also D1=5.
X0
The monitor interval of a programming tool depends on the processing speed of the programming tool. For the monitor
execution conditions established at the interval shorter than the monitor interval of the programming tool, monitor is
executed only when the monitor execution condition is established at the monitor timing of the programming tool.
Step No.

● With the High-speed Universal model QCPU and Universal model Process CPU, only the first data which satisfies the
specified conditions is collected if the step between the FOR and NEXT instructions is specified.
