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.

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:

pling)

ming Device.
