5 - 26 NX-series Digital I/O Unit User’s Manual (W521)
Additional Information
With the NX_DOutTimeStamp instruction, if you set a previous DC time unintentionally, a Previ-
ous Time Specified event will not occur and you can refresh the output immediately.
Refer to the
NJ-series Instructions Reference Manual (Cat. No. W502-E1-08 or later) for details
on the NX_DOutTimeStamp instruction.
