Generic term for GX Works2 and GX Developer.
One of the message formats for the serial communication modules used to communicate ASCII code
data through the MC protocol.
This is the same message format as the frames for communication through the dedicated protocol of
QnA series serial communication modules.
• QnA compatible 2C frame (formats 1 to 4): QnA simplified frame (formats 1 to 4)
One of the message formats for the serial communication modules used to communicate ASCII code
data through the MC protocol.
This is the same message format as the frame for communication through the dedicated protocol of
QnA series serial communication modules.
• QnA compatible 3C frame (formats 1 to 4): QnA frame (formats 1 to 4)
• QnA compatible 4C frame (formats 1 to 4): QnA extension frame (formats 1 to 4)
One of the message formats for the Ethernet interface modules used to communicate ASCII or binary
code data through the MC protocol.
This is the same message format as when reading/writing data from/to the programmable controller
CPU of a QnA series Ethernet interface module.
One of the message formats for the serial communication modules used to communicate binary code
data through the MC protocol.
This is the same message format as the frame for communication through the dedicated protocol of a
QnA series serial communication module.
• QnA compatible 4C frame (format 5): QnA extension frame (format 5)
Secure Digital Memory Card, which is a flash memory device.
The L1MEM-2GBSD and L1MEM-4GBSD are available.
A MELSEC-A/QnA series module that has other than input or output, such as A/D converter module
and D/A converter module.
Devices used to directly accesses the buffer memory of the special function module from the CPU
module.
In a redundant system, the Redundant CPU on the standby side prepared for control system failure.
In a redundant system, the Redundant CPU on the side to which the system A connector of the tracking
cable is connected.
In a redundant system, the Redundant CPU on the side to which the system B connector of the tracking
cable is connected.
Data name used when registering the fixed format section of a message to be communicated between
the serial communication module and an external device using the functions listed below, in order to use
it for data transmission and reception. (The contents of data in a user frame should be consistent with
the specifications of the external device.)
Used for registering the sequence of data of each of the head and ending sections in a communication
message (transmission control code, C24 station number, sum check, fixed data, etc.) to the serial
communication module.
• The on-demand function of the MC protocol
• Data transmission and reception functions through the non-procedure protocol.
One of the message formats for the Ethernet interface modules, in which ASCII or binary code data are
transferred with the MC protocol.
Any given number (serial No.) for message identification is added to the QnA compatible 3E frame.
By the serial No. which is added by the external device for message identification, the correspondence
between command and response messages can be checked.
