Mitsubishi Electronics A1SJ71QE71N-B5T Function, Performance Specifications, Other functions

[Function]

(1) Data communication function (TCP/IP Communication and UDP/IP Communication)

Communication Function		Description	QnA series	A series
Using read/write data in the PLC CPU		Reads/writes PLC CPU data from/to an external device.	!	!
Using fixed	Procedure exist	Reads/writes any data between PLC CPU and an external device	!	!
buffers	No Procedure	using fixed buffer of the Ethernet modules.
Using random access buffers		Exchanges data with multiple external devices, using the Ethernet	!	!
		random access buffers. (no need to specify external device)
Using data link instructions		Reads/writes PLC CPU data of other stations via the Ethernet	!	N/A
		using data link instructions.
File transfer (FTP Server Function)		Reads/writes files in the local station using the FTP server	!	N/A
		function, from an external device.

(2) Other functions

Function	Description	QnA series	A series
	Data communication is enabled over a network system where		N/A
MELSECNET/10 relay communication	Ethernet and MELSECNET/10 or multiple Ethernet networks are	!
	present.
Router relay communication (Router	Communicates data via routers and gateways. (Ethernet module	!	!
relay function)	does not function as a router.)
External device existence confirmation	Checks whether or not the external device operates normally after	!	!
	communication has been established (open processing).
Paring open communication	Receiving connection and transmitting connection are opened as a	!	!
	single pair. (For fixed buffer communication.)
Communication using automatic open	Communication is enabled automatically after initial processing is	!	N/A
UDP port	completed of local station Ethernet module. (Opening and closing
	by a sequence program is unnecessary.)
	Data is broadcasted simultaneously to all stations on the same
Simultaneous broadcast	Ethernet network where the Ethernet module is located. (Using	!	!
	UDP/IP)
Access PLC CPU from GX Developer	using Ethernet connection.	!	!
Please refer to the new module's User's Manual for the function versions and serial numbers of the products		!: Applicable
