Description
Memory in an intelligent function module for storing data such as setting values and monitored values.
When integrated into the CPU module, this memory refers to a memory for storing data such as setting values and
monitored values of the Ethernet function, and data used for data communication of the multiple CPU system function.
A generic term for the MELSEC iQ-R series CPU modules
A device (X, Y, M, D, or others) in a CPU module
A generic term for DP-Master (Class 1) and DP-Master (Class 2).
A device that exchanges I/O data with DP-Slaves. (Such as QJ71PB92D)
A device that communicates with DP-Slaves to check the FDL address setting and the operating status.
This device can perform start-up, maintenance, and diagnosis of the network as the DP-Master for the network control.
A device that exchanges I/O data with DP-Master.
Another name for the software package for the MELSEC programmable controllers This manual indicates GX Works3.
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 label that is automatically created by GX Works3 and a label that can be arbitrarily created
for a specified device.
A module that has functions other than input and output, such as an A/D converter module and D/A converter module
A label that represents a device in a given character string
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.
