TableApp.86 Specifications Comparison between Built-in Ethernet port QCPU and Ethernet module
Item Description
Availability
QnUDE(H)CPU QJ71E71-100
Communication
using MC
protocol
4E frame
Reads/writes data in the CPU module from/to an external
device.
A frame format that can receive multiple request messages
at a time.
QnA-
compatible
3E frame
Reading/
Writing data
in device
memory
Reads/writes data (device) in the CPU module from/to an
external device.
*1
Other
Reads/writes data (file) in the CPU module from/to an
external device.
A-compatible 1E frame
• Reads/writes data in the CPU module from/to an external
device.
• A frame format that is compatible with A series E71.
Communication
using fixed
buffer
With procedure
("Procedure exist")
Sends/receives arbitrary data between the CPU module and
an external device using the fixed buffer of the Ethernet
module.
Without procedure ("No
procedure")
Communication using random access
buffer
Reads/writes data from in the random access buffer of the
Ethernet module from/to multiple external devices.
Data communication (sending/receiving)
by e-mail
Sends/receives data by e-mail.
• Sending/receiving e-mail by the CPU module
• Sending/receiving e-mail using the CPU module
monitoring function (the automatic notification function) of
the Ethernet module
Communication using data link
instructions
Reads/writes data in the CPU module on another station via
Ethernet using data link instructions.
File transfer (FTP server function)
Reads/writes data in the CPU module in file units from/to an
external device using FTP commands.
*2
Communication using Web function
Accesses the CPU module from a personal computer in
remote locations via the Internet using a commercially
available Web browser.
CC-Link IE controller network,
MELSECNET/H, MELSECNET/10 relay
communication
Communicates data in the Ethernet, regarding the system as
equivalent to CC-Link IE controller network, MELSECNET/H
or MELSECNET/10.
Router relay communication (Router
relay function)
Communicates data via a router or gateway. (The router
relay function is not a function by which the Ethernet module
works as a router.)
*3
Send frame
setting
Ethernet (V2.0)
Sends data using the frame format selected for the Ethernet
header of the data link layer.
