TERMS
Unless otherwise specified, this manual uses the following terms.
Term Description
Buffer memory The intelligent function module's memory where the data (such as setting values and monitored values) transferred
from/to the CPU module is stored
Control method The generic term of two-position control, P control, PI control, PD control, and PID control
Control mode The generic term of standard control, heating-cooling control (normal mode), heating-cooling control (expanded mode),
mix control (normal mode), mix control (expanded mode), position proportional control (normal mode), and position
proportional control (expanded mode)
CPU module The generic term of MELSEC iQ-R series CPU modules
Engineering tool The product name of the MELSEC programmable controller software package
Fixed value action The operating status of when a constant set value (SV) is kept
Global label When multiple program data sets are created in a project, this label is valid for all the data sets. Global labels are
classified into two types: Module-specific labels (module labels) that are automatically created by GX Works3 and labels
that can be created for a specified device.
Module label The memory areas that are defined by each module (I/O signals or buffer memory area) and expressed with character
strings. GX Works3 automatically creates module labels from the module to be used. These labels can be used as
global labels.
PID constants The generic term of the proportional band (P), integral time (I), and derivative time (D)
Q compatible mode The buffer memory map is converted into the one for the MELSEC-Q series to operate the module.
R mode In this mode, the module operates with the buffer memory map that has been newly assigned for the MELSEC iQ-R
series.
Ramp action The operating status of when a set value (SV) always changes
Temperature sensor The generic term of thermocouples and platinum resistance thermometers
