NX-series Position Interface Units User’s Manual (W524)
Time stamping allows you to perform I/O controls based on time stamps when the Unit is used in com-
bination with the motion control instructions in the NJ/NX-series CPU Unit. You can estimate positions
according to workpiece travel times to achieve time-based controls that are not dependent on the task
periods in the CPU Unit.
For example, if you use sensors to detect workpieces moving on a conveyor, you can use time stamps
to estimate the positions of the workpieces based on elapsed times.
The following instructions are examples of the motion instructions that use time stamping.
• MC_DigitalCamSwitch
• MC_TimeStampToPos
Refer to the NJ/NX-series Motion Control Instructions Reference Manual (Cat. No. W508) for details on
the instructions.
