5-5 Operating Memory Area
CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
Outline of Operating Memory Area
The Operating Memory area is where the output bits that issue operation commands to the
PCU and the input bits used for indicating the PCU status are allocated.
The Operating area contains PCU control bits, Manual Operation Command Memory areas,
Direct Operation Command Memory areas, Axis Status Memory areas, Memory Operation
Command Memory areas and Memory Operation Status Memory areas.
The table below lists the memory areas which you use in each operation.
2 types of Operating Memory areas are available: one which is allocated as the PLC Special
I/O Unit area and the other set by common parameters.
The Operating Memory area is divided into outputs and inputs.
Commands that relate to operation are allocated to the Output Memory area, where you send
a command to the PCU while each bit is ON or the moment the bit turns ON for each bit.
Command data is also set.
Allocated in the Input area are internal PCU status and external I/O status, where applicable
data is input from the PCU.
If you use a CJ1W-NC414/NC434 4-axis PCU and set axes 1 and 2 as Physical Axes with the
remaining 2 axes set as unused axes, for example, each memory area occupies 2 axes only.
If you set different 2 axes, namely axes 1 and 3 as Physical Axes with the remaining 2 axes
set as unused axes, each area occupies 3 axes.
