6. Introduction of Functions
6.1 Functions List
This section shows a list of Ethernet adapter functions.
6.2 Details of functions
6.2.1 MELSOFT connections
This function allows communication with a MELSOFT product (such as GX Work2) in the LAN (such as
company LAN).
This function is equivalent to the communication function supported on the RS-422 port in the PLC main unit,
and provides the following:
• Reading, writing (including writing during RUN) and verification of programs
• Reading and test of devices in the PLC main unit (including buffer memories in special function blocks)
This function is activated when the open method of the connection No. used for the open setting is set to
"MELSOFT connections".
For operation of GX Works2, refer to Section 8.2.
6.2.2 Communication Using MC Protocol
For details of MC Protocol, refer to Chapter 7.
Functions Description Reference section
MELSOFT connections
This function allows communication with a MELSOFT product (such as GX Work2)
on a LAN (such as company LAN).
Subsection 6.2.1
Communication Using MC
Protocol This function reads/writes the PLC data from/to an external device, and supports
subsets of the A-compatible 1E frame.
Chapter 7
MELSOFT Direct Connection
(Simple Connection)
This function connects the Ethernet adapter attached to the main unit to a MELSOFT
product (such as GX Works2) with one Ethernet cable without using a hub, and
enables communication when only the connection destination is specified. It is not
necessary to set the IP address.
Subsection 6.2.3
Find CPU function
This function searches (PLC CPUs connected to) Ethernet adapters connected to
the same hub as the personal computer using GX Works2, and enables selection of
a desired CPU from the list of found CPUs and acquisition of the IP address.
Subsection 6.2.4
Time setting function
This function accesses the time information server (SNTP server) connected to the
LAN, collects the time information, and automatically sets the time to the main unit.
Subsection 6.2.5
Parameter setting function
This function sets parameters of the Ethernet adapter from GX Works2 via the main
unit.
Subsection 6.2.6
Diagnostics function from
MELSOFT This function diagnoses the Ethernet adapter from GX Works2 via the main unit.
