One of the attributes of a variable.
This attribute allows the user to specify what is assigned to a variable. An I/O
port or an address in memory used for CJ-series Units can be specified.
Any of the CJ-series Units that can be used with an NJ-series Controller.
One type of I/O memory that contains addresses to which variables can be as-
signed, for example, when accessing a CJ-series Unit or CJ-series network. It
can be accessed only with variables with an AT attribute.
The Unit that serves as the center of control for a Machine Automation Control-
ler. The CPU Unit executes tasks, refreshes I/O for other Units and slaves, etc.
The NJ/NX-series CPU Units include the NX701-££££, NX102-££££,
NX1P2-££££, NJ501-££££.
One of the function modules. This function module controls the EtherCAT slaves
as the EtherCAT master.
One of the function modules. This function module controls the built-in
EtherNet/IP port.
An acronym for "function block."
An abbreviation for "function."
A logical interface that is used by the CPU Unit to exchange data with an exter-
nal device (slave or Unit).
Settings that assign variables to I/O ports. Assignment information between I/O
ports and variables.
Cyclic data exchange with external devices that is performed with predetermined
memory addresses.
A function to check motor operation and wiring from the Sysmac Studio.
An internal bus of the NX-series Controller.
Any of the NX-series Units that perform I/O processing with connected external
devices. The Communications Coupler Units are not included with the NX Units.
An abbreviation for process data communications. Data is exchanged between
the master and slaves on a process data communications cycle. (The process
data communications cycle is the same as the task period of the primary periodic
task.)
One of the function modules. This function module executes the user program,
sends commands to the Motion Control Function Module, and provides an inter-
face to the USB and SD Memory Card.
An acronym for "program organization unit". A POU is a unit in a program execu-
tion model that is defined in IEC 61131-3.
A POU contains an algorithm and a local variable table and forms the basic unit
used to build a user program.
There are three types of POUs: programs, functions, and function blocks.
One type of EtherCAT communications in which service data objects (SDOs) are
used to transmit information whenever required.
A computer software application for setting, programming, debugging, and trou-
bleshooting NJ/NX-series Controllers. It also provides operations for motion con-
trol and a Simulator.
To transfer data from the Controller to the Sysmac Studio with the synchroniza-
tion operation of the Sysmac Studio.
