ing execution of differentiation moni-
toring.

A508.11 Trace Trig-
ger Monitor
Flag
ON when a trigger condition is estab-
lished by the Trace Start Bit
(A508.14). OFF when the next Data
Trace is started by the Sampling
Start bit (A508.15).
ON: Trigger

A508.12 Trace Com-
pleted Flag
ON when sampling of a region of
trace memory has been completed
during execution of a Trace.
OFF when the next time the Sam-
pling Start Bit (A508.15) is turned
ON.

completed
OFF: Not trac-
ing or trace in
progress

A508.13 Trace Busy
Flag
ON when the Sampling Start Bit
(A508.15) is turned ON. OFF when
the trace is completed.
ON: Trace in
progress
OFF: Not trac-
ing (not sam-
pling)

A508.14 Trace Start
Bit
Turn this bit ON to establish the trig-
ger condition. The offset indicated by
the delay value (positive or negative)
determines which data samples are
valid.

ger condition
established
OFF: Not
established

A508.15 Sampling
Start Bit
When a data trace is started by turn-
ing this bit ON from the CX-Program-
mer, the PLC will begin storing data
in Trace Memory by one of the three
following methods:
1) Data is sampled at regular inter-
vals (10 to 2,550 ms).
2) Data is sampled when TRSM(045)
is executed in the program.
3) Data is sampled at the end of
every cycle.
The operation of A508.15 can be
controlled only from the CX-Pro-
grammer.
OFF to ON:
Starts data

pling)
Turned ON

ming Device.
