(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.

 

 

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)

GX Configurator-SC

 

• 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.)

 

 

 

 

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:

Intelligent function modules

 

• 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

 

GX Configurator-SC Version 2 Operating Manual (Protocol FB support function)

(Protocol FB support function)

 

 

 

Opposite 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

(external devices)

 

 

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.

 

 

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:

Special function modules

 

• 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
