Function
Turn these bits ON to restart (initialize)
the Special I/O Unit with the corre-
sponding unit number. Bits A50200 to
A50715 correspond to unit numbers 0
to 95.
When a restart bit is turned ON, the
corresponding Special I/O Unit Initializ-
ing Flag (A33000 to A33515) will be
turned ON. Both the restart bit and ini-
tializing flag will be turned OFF auto-
matically when initialization is
completed. Do not turn the bit OFF
from a Programming Device or the lad-
der program.
ON when the differentiate monitor con-
dition has been established during exe-
cution of differentiation monitoring.
(This flag will be cleared to 0 when dif-
ferentiation monitoring starts.)
ON when a trigger condition is estab-
lished by the Trace Start Bit (A50814).
OFF when the next Data Trace is
started by the Sampling Start bit
(A50815).
ON when sampling of a region of trace
memory has been completed during
execution of a Trace.
OFF when the next time the Sampling
Start Bit (A50815) is turned from OFF
to ON.
ON when the Sampling Start Bit
(A50815) is turned from OFF to ON.
OFF when the trace is completed.
Turn this bit from OFF to ON to estab-
lish the trigger condition. The offset
indicated by the delay value (positive or
negative) determines which data sam-
ples are valid.
When a data trace is started by turning
this bit from OFF to ON from a Pro-
gramming Device, the PLC will begin
storing data in Trace Memory by one of
the three following 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.
The operation of A50815 can be con-
trolled only from a Programming
Device.
These words contain the time at which
the power was turned ON. The con-
tents are updated every time that the
power is turned ON. The data is stored
in BCD.
