Name
Trace ON when sampling of a region of
Completed trace memory has been com-
Flag pleted during execution of a
Trace.
OFF when the next time the
Sampling Start Bit (A50815) is
turned from OFF to ON.
Trace Busy ON when the Sampling Start Bit
Flag (A50815) is turned from OFF to
ON. OFF when the trace is com-
pleted.
Trace Start Turn this bit from OFF to ON to
Bit establish the trigger condition.
The offset indicated by the delay
value (positive or negative) de-
termines which data samples are
valid.
Sampling When a data trace is started by
Start Bit turning this bit from OFF to ON
from a Programming Device, the
PLC will begin storing data Trace
Memory by one of the three fol-
lowing methods:
1) Data is sampled at regular
intervals (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.
SYSMAC Turn this bit ON to refresh the
BUS Slave error information in A425 (unit
Number number of Slave where error
Refresh Bit occurred after startup).
Start-up These words contain the time at
Time which the power was turned ON.
The contents are updated every
time that the power is turned ON.
The data is stored in BCD.
