Features

The features specific to the Built-in Ethernet port QCPU are described below.
(1) Connection of programming tools and GOTs (
• The Find CPU function makes it possible to find the Built-in Ethernet port QCPU connected to the same hub
as programming tool and displays a list.
• Access is available via routers on a network such as a corporate LAN.
• GOT on Ethernet can be accessed from the programming tool via the built-in Ethernet port of a CPU module.
(2) Direct connection to a programming tool (simple connection) (
CHAPTER 4)
The CPU module can be directly connected to a programming tool with a single Ethernet cable only, without
using a hub (simple connection). In direct connections, communications can be performed simply by the transfer
setup, without setting IP addresses.
(3) MC protocol communication (
From an external device such as a personal computer or HMI, device data of the CPU module can be read or
written using MC protocol commands.
In addition, MC protocol messages (QnA-compatible 3E frame and 4E frame) can be sent from the CPU module
to external devices connected on the Ethernet network.
(4) Data communications using the predefined protocol (
6)
The predefined protocol function sends and receives packets predefined by using GX Works2, enabling easy
communications with external devices (such as measuring instruments and bar code readers). Protocol can be
either selected from the prepared predefined protocol library, or created and edited by users.
(5) Socket communication function (
By using instructions dedicated to socket communication, any data can be transferred from and to the external
devices connected through Ethernet using TCP or UDP.
(6) Time setting function (SNTP client) (
• Automatic time setting of the CPU module can reduce the maintenance cost for time setting.
• By sharing the same clock data among CPU modules connected to Ethernet via their built-in Ethernet ports,
the order of errors between processes can be traced, facilitating problem solving.
• Since the automatic time setting is enabled upon power-on of the CPU module, operations can be started
based on accurate clock data.
