The area allocated as the operating memory area is contained in the Special I/O
Unit Area within the CPU Unit's CIO Area. The beginning word of the operating
memory area is determined according to the unit number set for the PCU
according to the following equation.
Beginning word of operating memory area, n = 2000 + 100 × unit number
The operating memory area is divided into outputs and inputs. Commands
related to operations are allocated to the output memory area, and the com-
mands are output to the Position Control Unit (PCU) when their respective bits
are turned ON, or at the rising edge (↑) when the bits are turned ON. The PCU's
status and the status of external I/O are input from the PCU to the operating
memory area.
The memory allocation of the operating memory area is shown in the following
table. For details such as operation timing, refer to the section for the relevant
function.

Operation p
In memory operation, this setting
specifies whether the sequence
number designated in the operating
data area is enabled or disabled for
beginning operation.
At the rising edge (↑) when this bit
turns ON, memory operation starts.
At the rising edge (↑) when this bit
turns ON, memory operation starts.
The completion code is treated as
"terminating," except for when it is set
to "bank end."
At the rising edge (↑) when this bit
turns ON, direct operation is started
with the position designated in the
operating data area treated as an
absolute position.
At the rising edge (↑) when this bit
turns ON, direct operation is started
with the position designated in the
operating data area treated as a
relative position.
At the rising edge (↑) when this bit
turns ON, interrupt feeding begins for
direct operation.
At the rising edge (↑) when this bit
turns ON, an origin search is executed.
At the rising edge (↑) when this bit
turns ON, positioning returns to the
origin.
At the rising edge (↑) when this bit
turns ON, the present position is
forcibly changed to the position set in
the operating data area, and then this
position is established as the origin.
