Description
The assignment information of the tag data assigned to the file register. The device information of the CPU module is
stored.
The abbreviation for the MELSEC iQ-R series CPU module
The product name of the software package for the MELSEC programmable controllers
Gauge window on which an indicator such as a controller is displayed in image format Monitoring the tag data and
changing the current value can be performed.
The VAR_PUBLIC or VAR_PUBLIC_RETAIN class label among the local labels defined in FB. For the tag FB, the tag
data member is included in the tag FB member.
Setting the initial value for the FB property or changing the current value during a program execution changes the
function block operation.
The abbreviation for the function block diagram/ladder diagram
An FBD/LD program with the extended function for the process control
A label that represents a device in a given character string
Extending the functions of the engineering tool for the instrumentation engineering
In the engineering tool project of the Process CPU and the SIL2 Process CPU, the function block supplied by the
manufacturer that can be used in the FBD/LD program with the process control extension enabled.
The process control instruction corresponding to the Process CPU and the SIL2 Process CPU is executed in the
function block.
A generic term for the R08PCPU, R16PCPU, R32PCPU, and R120PCPU
A generic term for the R08PSFCPU, R16PSFCPU, R32PSFCPU, and R120PSFCPU.
This module is used with a SIL2 function module as a pair, and performs both standard control and safety control. This
module is also used with a redundant function module as a pair and configures a redundant system.
The process control function block that can be used only in the user-defined tag FB.
Accessing the tag data of the user-defined tag FB executes the processing.
The data where the process conditions and process status data associated with the tag FB are arranged. The
engineering tool creates the tag data as a structure.
A function block with the process control function which works as a controller or an indicator.
The tag data defined as the global label is used.
Classification of the process control function which works as a controller or an indicator. The tag type determines the
structure type of the tag data and the faceplate type.
The function block that can customize the process control processing of the manufacturer-defined tag FB.
The tag data can be referred from the FB program created by combining the function, function block, and process
control function block.
