NX-series NX102 CPU Unit Hardware User's Manual (W593)
One of the event levels for Controller events or user-defined events. These are
not errors, but appear in the event log to notify the user of specific information.
Settings that define user-defined errors and user-defined information.
A task that executes a user program only once when the task execution condi-
tions are met.
A function that recognizes and records errors and other events.
ST programming that is included within a ladder diagram.
One of the attributes of a variable.
This attribute makes a BOOL variable pass TRUE to a function block when the
variable changes from FALSE to TRUE or when it changes from TRUE to
FALSE.
A variable that represents the cam data as a structure array.
A cam data variable is an array structure that consists of phases and displace-
ments.
One of the event levels for Controller events or user-defined events.
These are minor errors that do not affect control operations, but appear in the
event log to notify the user of specific information.
One of the functional units of the software configuration of the CPU Unit.
Any of the data types that are defined by IEC 61131-3.
They include Boolean, bit string, integer, real, duration, date, time of day, date
and time, and text string data types.
"Basic data type" is used as opposed to derivative data types, which are defined
by the user.
Forcing the refreshing of an input from an external device or an output to an ex-
ternal device, e.g., when the user debugs a program.
Addresses that are subject to forced refreshing can still be overwritten from the
user program.
One of the derivative data types. It allows you to handle the same data as differ-
ent data types.
A variable that can be read or written from all POUs (programs, functions, and
function blocks).
An error for which some 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 minor fault level
Controller error occurs.
A generic term for the settings for a Special Unit, including the settings in allocat-
ed DM Area words.
One of the derivative data types. It consists of multiple data types placed togeth-
er into a layered structure.
One of the attributes of a variable.
If you specify the Constant attribute for a variable, the value of the variable can-
not be written by any instructions, ST operators, or CIP message communica-
tions.
The range of devices that are directly controlled by the CPU Unit.
In the NX-series System, the Controller includes the CPU Rack and EtherCAT
slaves (including general-purpose slaves and Servo Drives).
In the NJ-series System, the Controller includes the CPU Rack, Expansion
Racks, and EtherCAT slaves (including general-purpose slaves and Servo
Drives).
