An E71 can be connected with MELSOFT products, such as a programming tool and
MX Component, and a GOT.
CPU module data can be read/written from/to connected devices. Access to files can
be also performed.
The connected device can read/write data from/to the buffer memory or device of an
SLMP supporting device connected to the shared network with the E71. In addition,
the connected device can read/write data from/to the device of the CPU module
where an E71 is mounted.
Data can be sent/received with protocols appropriate to each connected device.
The connected device side protocol can be easily selected, or created/edited from
the Predefined Protocol Library of GX Works2.
Any data is sent/received between a CPU module and connected devices using the
fixed buffer of an E71.
Paring receiving/sending connections enables data communications with two
connections by performing the open process for one port.
Broadcast communications are enabled with all E71-mounted stations in the same
Ethernet network that is connected to the E71 when "No Procedure"
communications using a fixed buffer are performed using UDP/IP.
Data is read/written from multiple connected devices to the random access buffer of
an E71.
Data communications are performed through a router and a gateway. This function
is not the function where an E71 operates as a router.
Communications are enabled without the open/close processes after an E71-
mounted station is started up.
The IP address of the connected device to be allowed or denied access is set in the
buffer memory, and access from connected devices is restricted.
Unauthorized remote access to a CPU module is prevented.
The current connection status and transmission speed of an E71 and a hub and the
number of times that the E71 detected disconnection can be checked.
If different stations in the same network use the same IP address, the address in use
can be detected.
A network can be configured in a redundant system.
Whether a connected device is normally operating after a connection is established
(open process) can be checked.
