Description
A tool used for setting up programmable controllers, programming, debugging, and maintenance
A label that is valid for all the program data when multiple program data are created in the project.
The global label has two types: a module specific label (module label), which is generated automatically by GX Works3,
and an optional label, which can be created for any specified device.
A label that represents one of memory areas (I/O signals and buffer memory areas) specific to each module in a given
character string.
For the module used, GX Works3 automatically generates this label, which can be used as a global label.
Description
A generic term for devices that have control of the GP-IB communications system. Only one device can serve as the
controller in the system.
A generic term for data relevant to device functions and specific to each device. The data are communicated as device
dependent messages.
A generic term for functions specific to each device, such as a measurement function of voltage or frequency
An abbreviation for the MELSEC iQ-R series GP-IB interface module
A generic term for messages used by the controller to control the other devices.
The messages sent using one signal line are called a uniline message, and the commands communicated using
multiple signal lines are called a multiline messages.
