Connection with MELSOFT Product and GOT

Programming and monitoring of the programmable controller with the engineering tool, and monitoring and testing of the
programmable controller from the GOT can be performed via Ethernet. This function enables remote operations using
Ethernet's long-distance connection and high-speed communication.
The section describes the methods of connecting the Ethernet-equipped module, MELSOFT product (such as engineering
tool and MX Component), and GOT.

Setting procedure

■Setting in the Ethernet-equipped module side

Set the IP address of the Ethernet-equipped module in "Own Node Settings" under "Basic Settings". ( Page 242 Own
Node Settings)
When connecting by specifying the network number and station number, set the network number and station number in "Own
Node Settings" under "Basic Settings".
Even if "External Device Configuration" is not set under "Basic Settings", the Ethernet-equipped module can be connected to
the MELSOFT product and GOT using the system dedicated connection.
*1 When using a TCP/IP connection with the system dedicated connection, up to ((maximum number of connected modules in "External
Device Configuration") - (set number) + 1) modules can be connected.
When using a UDP/IP connection, up to the maximum number of connectable modules can be connected.
