Description
A memory in an intelligent function module, where data (such as setting values and monitoring values)
exchanged with a CPU module are stored
The abbreviation for the configuration tool for flexible high-speed I/O control modules
Another term for GX Works3
The memory in a flexible high-speed I/O control module where the hardware logic is written
Wiring between a flexible high-speed I/O control module and external devices
A non-volatile memory to which the hardware logic can be written. Although the number of writes to a flash
ROM is limited, the written hardware logic is not deleted even after the power off and automatically read at the
power-on.
The abbreviation for the MELSEC iQ-R series flexible high-speed I/O control module
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.
The product name of the software package for the MELSEC programmable controllers
A control logic that users create graphically combining inputs, outputs, logical operation circuits, and counters
with the configuration tool
Connecting blocks or terminals on the configuration tool
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.
An error that occurs if the internal processing of the flexible high-speed I/O control module is abnormal.
Watchdog timer enables the module to monitor its own internal processing.
