Table6.21 Trace point setup item
Item
Description
Each scan
Collects trace data during END processing of each scan.
Interval
Collects trace data at specified time intervals.
Detail
A trace point (device and/or step number) needs to be set.
The following devices can be set as a trace point.
• Bit device: X(DX), Y(DY), M, L, F, SM, V, B, SB, T(contact), ST(contact), C(contact),
FX, FY, J \X, J \Y, J \B, J \SB, BL \S
• Word device: T(current value), ST(current value), C(current value), D, SD, W, SW, R, Z, ZR, FD, U \G,
J \W, J \SW
The following modifications are available for the above devices.
• Digit specification of bit device
• Bit specification of word device
• Indirect specification of word device
• Index modification
When the set conditions are met, data collection is performed. The following shows the conditions of setting
items.
The collection timing for trace data when "Step No." is selected is the same as when setting the monitor
conditions. (
