1 Overview and Features
When a device variable name for CJ-series Unit is assigned with method 2 or 3, the variable input by
Sysmac Studio is automatically registered in the variable table.
The following is the configuration of variable names created with method 3.
Device variable (name) for CJ-series Unit
*_ Ch1_L_PVAlmSta
In the explanations from here on, the device name automatically created is used as the device variable
for CJ-series Unit, for example *_Ch1_L_PVAlmSta.
For details on creation of device variables for CJ-series Unit, refer to the Sysmac Studio Version 1
Operation Manual (Cat. No. W504).
User-defined Variables
User-defined variables are necessary to access Expansion Operation Data and Expansion Setting
Parameters data.
With the CJ1W-PDC15/-PH41U, structure data types for Expansion Operation Data and Expansion
Setting Parameters are pre-defined. To use one of these data types, register the structure data type
specified for each unit on the CPU/Expansion Racks screen in Configurations and Setup.
Create user-defined variables by using the above structures so that the user program can access
Expansion Operation Data and Expansion Setting Parameters.
The user program uses user-defined variables to control the Analog I/O Unit.

How to create user-defined variables for Expansion Setting Parameters and
Expansion Operation Data
1
Register the Analog I/O Units in the Unit Configuration.
Then, register the structure data type specified for each unit on the CPU/Expansion Racks
screen in Configurations and Setup. With the unit selected, right click Register Data Types for
Units. The data type is registered and becomes usable.
2
With Special Unit Setup Editing in Sysmac Studio, set addresses of memory used for CJ-
series Unit for Expansion Setting Parameters and Expansion Operation Data. Transfer the set-
tings to the CPU Unit, and then restart the Unit to enable the settings.
At this time, make sure that the allocated areas do not exceed the available ranges in the CPU
memory so that the addresses already in use are not duplicated.
1-28
This is an I/O port name. The name indicates the unit function,
status and parameter.
This is the device name when this Unit is registered in the unit
configuration. (By default, a device name is assigned from "J01"
in the order of registration in the unit configuration.) This
identifies the individual unit.
