2. Ethernet Interfaces
2-1. Overview of Ethernet Interfaces
Th e MG41 main unit supports two interfaces with the Ethernet. Connection to the command interface
must be made without fail.
Type of interface Protocol Purpose
Command transmission/
reception Data acquisition
Command
interface telnet Possible Th e ASCII data is successively acquired
using the data acquisition command.
Data interface TCP or UDP Not possible Binary data is continuously transferred.
Use the interfaces corresponding to the specifi cations of the soft ware to be created.
When only the
command interface is
used

Th e connections are straightforward.

A simple system can be confi gured because the data and commands use the
ASCII format.

Th e data transfer rate is slower than when the command interface is used together
with the data interface.
When both the
command interface and
data interface are used

Th e application must manage two interfaces and ensure that each is best used
according to the prevailing conditions and functions used.

Binary data must be interpreted and computed.

Higher data transfer rates can be expected.
For an example of a case where only the command interface is used, refer to “2-4. Setting Examples” ; for
an example of a case where both the command interface and data interface are used, refer to “2-5. When
Both the Command Interface and Data Interface Are Used” .
A protocol of the application layer of its own is stipulated for the data interface. Th is means that if the
interface is to be connected to an existing network, it may be necessary to apply to the network administrator
for the connection and/or change the network equipment settings and/or computer security settings.
