Operating Memory Area
Section 4-5

Operating Memory Area
The operating memory area is the area in the CIO Area allocated to the out-
puts used for sending commands to the PCU and the inputs used for monitor-
ing PCU status.
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 oper-
ating 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 + 10
×
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 follow-
ing table. For details such as operation timing, refer to the section for the rele-
vant function.

Operation
01
START
At the rising edge (
↑
) when this bit turns
ON, memory operation starts.
02
INDEPEN-
DENT START
At the rising edge (
↑
) when this bit turns
ON, memory operation starts. The com-
pletion code is treated as “terminating,”
except for when it is set to “bank end.”
03
Direct opera-
tion com-
mands
ABSOLUTE
MOVEMENT
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.
SECTION 7
Direct Opera-
tion
04
RELATIVE
MOVEMENT
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.
05
INTERRUPT
FEEDING
At the rising edge (
↑
) when this bit turns
ON, interrupt feeding begins for direct
operation.

07
ORIGIN
RETURN
At the rising edge (
↑
) when this bit turns
ON, positioning returns to the origin.
08
PRESENT
POSITION
PRESET
At the rising edge (
↑
) when this bit turns
ON, the present position is forcibly
changed to the position set in the operat-
ing data area, and then the origin is estab-
lished based on the changed present
position.
