Sampling Start Bit
A508.15
When a data trace is started by turning this bit ON from
the CX-Programmer, the PLC will begin storing data in
Trace Memory by one of the three following methods:
Data is sampled at regular intervals (10 to 2,550 ms).
Data is sampled when TRSM(045) is executed in the
program.
Data is sampled at the end of every cycle.
Read/write
Trace Start Bit
A508.14
Turn this bit ON to establish the trigger condition. The off-
set indicated by the delay value (positive or negative)
determines which data samples are valid.
Read/write
Trace Busy Flag
A508.13
ON when the Sampling Start Bit (A508.15) is turned ON.
OFF when the trace is completed.
Read/write
Trace Completed Flag
A508.12
ON when sampling of a region of trace memory has
been completed during execution of a trace.
Read/write
Trace Trigger Monitor Flag
A508.11
ON when a trigger condition is established by the Trace
Start Bit (A508.14). OFF when the next data trace is
started by the Sampling Start Bit (A508.15).
