[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.
!
!
Procedure exist Using fixed
buffers
No Procedure
Reads/writes any data between PLC CPU and an external device
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
using data link instructions.
! N/A
File transfer (FTP Server Function)
Reads/writes files in the local station using the FTP server
function, from an external device.
! N/A
(2) Other functions
Function Description QnA series A series
MELSECNET/10 relay communication
Data communication is enabled over a network system where
Ethernet and MELSECNET/10 or multiple Ethernet networks are
present.
!
N/A
Router relay communication (Router
relay function)
Communicates data via routers and gateways. (Ethernet module
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
UDP port
Communication is enabled automatically after initial processing is
completed of local station Ethernet module. (Opening and closing
by a sequence program is unnecessary.)
!
N/A
Simultaneous broadcast
Data is broadcasted simultaneously to all stations on the same
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
(CPU module and GX Developer) related to the above functions.
