FQ2-S4 User’s Manual
Accessing Communications Areas Using Variables with NJ-series Controllers
With an NJ-series Controller, only variables can be used to access from the user program the I/O memory
addresses that are assigned to the communications areas.
Use the following settings.
●
Using Network Variables for Access
Create user-defined variables that match the structures of the communications areas of the Sensor.
Use the Sysmac Studio to define the variables.
Refer to the
Sysmac Studio Version 1 Operation Manual
(Cat. No. W504) for Sysmac Studio operating
procedures.

Defining the Data Types of the Variables
Define data types for variables that match the structures of the communications areas.
(1)
Defining a Data Type for Signal Access
First, define a BOOL array data type to access the control signals and status signals.
Here, a data type called “U_EIPFlag” is defined.
Name of data type: U_EIPFlag
Type of derivative data type: Union
(2)
Defining Data Types for Communications Area Access
Data types are defined to access the communications areas, with one data type for the command area
and another data type for the response and output areas.
Here, data types called “S_EIPOutput” and “S_EIPInput” are defined.
• Data Type to Access the Command Area
Name of data type: S_EIPOutput
Type of derivative data type: Structure
U_EIPFlag
