Function
This flag indicates whether the
high-speed counter is currently being
incremented or decremented. The
counter PV for the current cycle is com-
pared with the PV in last cycle to deter-
mine the direction.
OFF: Decrementing
ON: Incrementing
These words contain the maximum
value of the differentiation flag num-
bers being used by differentiation
instructions.
These words contain the CPU Unit's
internal clock data in BCD. The clock
can be set from the CX-Programmer,
with the DATE instruction, or with a
FINS command (CLOCK WRITE,
0702).

Note 1 The data will be unstable if the
capacitor becomes dis-
charged. Write the ladder pro-
gram and design the overall
system to handle any prob-
lems that might occur if this
data becomes unstable.
2 In an E-type CPU Uint, or if the
clock data is not set for an
N/NA-type CPU Unit, the data
will be for 1:01.01 on Sunday
January 1, 2001.
The flag corresponding to the specified
FAL number will be turned ON when
FAL is executed. Bits A360.01 to
A391.15 correspond to FAL numbers
001 to 511.
Note The flag will be turned OFF when
the error is cleared.
