Function
ON when the differentiate monitor
condition has been established dur-
ing execution of differentiation moni-
toring.
(This flag will be cleared to 0 when
differentiation monitoring starts.)
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 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.
ON when the Sampling Start Bit
(A508.15) is turned ON. OFF when
the trace is completed.
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.
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.
