Sampling Start Bit A508.15 Use the CX-Programmer to turn ON this bit to start sampling. This bit must be
turned ON from the CX-Programmer. Do not turn this bit ON and OFF from the
user program.
Note: The bit will be turned OFF when the Data Trace has been completed.
Trace Start Bit A508.14 When this bit is turned ON, the trace trigger will be monitored and sampled data
will be stored in Trace Memory when the trigger condition is met. The following
traces are enabled with this bit.
1) Scheduled trace (trace at fixed intervals of 10 to 2,550 ms)
2) TRSM(045) instruction trace (trace when the TRSM(045) is executed)
3) One-cycle trace (trace at the end of execution of all cyclic tasks)
Trace Trigger Monitor Flag A508.11 This flag turns ON when the trace trigger condition has been met after the Trace
Start Bit has turned ON. This flag will turn OFF when the sampling is started.
Trace Busy Flag A508.13 This flag turns ON when sampling is started and turns OFF when the trace has
been completed.
Trace Completed Flag A508.12 This flag turns ON when Trace Memory becomes full after the trace trigger con-
dition has been met during a trace operation and turns OFF when the next sam-
pling operation is started.
