This data is used to restore in the CPU Unit the actual position of a Servo Drive
with an absolute encoder. The offset is the difference between the command po-
sition after homing and the absolute data that is read from the absolute encoder.
A unit version to be set for the project. It is set for the project in the Select Device
Area of the Project Properties Dialog Box on the Sysmac Studio.
An error for which all NJ/NX-series Controller control operations stop. The CPU
Unit immediately stops user program execution and turns OFF the loads for all
slaves and Units (including remote I/O).
To transfer data from the Sysmac Studio to the Controller with the synchroniza-
tion operation of the Sysmac Studio.
An attribute that defines when a program is executed.
The interval at which the primary periodic task or a periodic task is executed.
The generic name of an interface unit for remote I/O communications on a net-
work between NX Units and a host network master. For example, an EtherCAT
Coupler Unit is a Communications Coupler Unit for an EtherCAT network.
A tasks for which user program execution and I/O refreshing are performed each
period.
A general term for any Unit or slave that is refreshed by the I/O refreshing that is
performed by the CPU Unit. Specifically, it refers to EtherCAT slaves, NX Units
on the CPU Unit, built-in I/O, Option Boards, and CJ-series Units.
An output for any Unit or slave that is refreshed by the I/O refreshing that is per-
formed by the CPU Unit.
A variable that is used to access a specific device through an I/O port.
A function that automatically compares the information in the NJ/NX-series Con-
troller with the information in the Sysmac Studio, displays any differences and lo-
cations in a hierarchical form, and can be used to synchronize the information.
A system that is used to group and nest the names of functions, function block
definitions, and data types.
One of the attributes of a variable.
This attribute allows you to use CIP message communications or tag data links
to read/write variables from another Controller or from a host computer.
One of the variable specifications. An array variable contains multiple elements
of the same data type. The elements in the array are specified by serial numbers
called subscripts that start from the beginning of the array.
A data type that is defined by the user. Structures, unions, and enumerations are
derivative data types.
One of the variable specifications. You can specify a range for a variable in ad-
vance. The variable can take only values that are in the specified range.
Any of the EtherCAT slaves that cannot be assigned to an axis.
A POU that is used to create an object that determines a unique output for the
same input, such as for data processing.
A POU that is used to create an object that can have a different output for the
same input, such as for a timer or counter.
An error for which all of the control operations for one of the function modules in
the NJ/NX-series Controller stop.
An NJ/NX-series CPU Unit continues operation even after a partial fault level
Controller error.
The task with the highest priority.
Along with functions and function blocks, one of the three types of POUs.
Programs are assigned to tasks to execute them.
