(2) Other generic terms and abbreviations
This manual uses the following generic terms and abbreviations to explain the
data-communication devices for the serial communication module. The
names/model names are provided when it is necessary to explicitly identify the
model being discussed.
Generic term/abbreviation Description of generic term/abbreviation
Buffer memory
Generic term for memory of the intelligent function modules/special function modules used for
storing data sent to or received from the PLC CPU (setting values, monitor values, etc.)
Computer
Generic term for one of the external devices with which data can be sent/received using the MC
protocol or the bidirectional protocol.
Data communication functions Generic term for MC protocol, non procedure protocol, and bidirectional protocol.
GX Configurator-SC
Abbreviation for GX Configurator-SC (SW0D5C-QSCU-E or later).
• Initial settings for the module, monitoring and testing can be performed without using a sequence
program and without considering I/O signals or buffer memory. (Intelligent function utility)
• Converting sequence programs necessary for data communication processing into FB can
shorten program production man-hours.
In addition, the monitoring and analysis of the transmitted/received data by the communication
network can shorten the system start-up time. (Protocol FB support function)
GX Developer Abbreviation for GX Developer (SWnD5C-GPPW-E). (n in the model should be 4 or greater)
I/F Abbreviation for interface
Intelligent function module devices
Generic term for buffer memory of the intelligent function modules used for storing data sent to or
received from the PLC CPU (setting values, monitor values, etc.)
Intelligent function modules
Generic term for the Q series PLC modules that are operated by commands from the PLC CPU
(equivalent to the A series PLC special function modules).
Examples:
• CC-Link interface module
• A/D and D/A conversion modules
• Ethernet interface module
• Serial communication module
MELSECNET/10 Abbreviation for MELSECNET/10 network system.
MELSECNET/H Abbreviation for MELSECNET/H network system.
MX Component Abbreviation for MX Component (SW0D5C-ACT-E or later).
Operating Manual
(Protocol FB support function)
GX Configurator-SC Version 2 Operating Manual (Protocol FB support function)
Opposite devices
(external devices)
Generic term for computers, indicators, measuring instruments, ID modules, bar code readers,
regulators, other serial communication modules, UC24, etc. that are connected to this serial
communication module for data communication.

RS-232 (interface) Abbreviation for interface conforming to RS-232.
RS-422/485 (interface) Abbreviation for interface conforming to RS-422 and RS-485.
Special function modules
Generic term for the A/QnA series PLC modules that are operated by commands from the PLC
CPU (equivalent to the Q series PLC intelligent function modules).
Examples:
• CC-Link interface module
• A/D and D/A conversion modules
• High-speed counter module
• Ethernet interface module
• Computer link module and serial communication module
Switch setting Generic term for intelligent function module switch setting
