Network Settings
This section describes the settings for using Ethernet port 1 or the HMI-Ethernet port to connect the FC6A Series MicroSmart to a
network.
Description
In order for the FC6A Series MicroSmart to connect to an Ethernet network, the FC6A Series MicroSmart network settings (FC6A
Series MicroSmart IP address, subnet mask, default gateway, and DNS server addresses) must be acquired or configured
according to the specification method.
IP Settings
The specification method for the FC6A Series MicroSmart IP address, subnet mask, and default gateway can be selected as the
following three types.
Notes:
•
The default FC6A Series MicroSmart settings are: IP address 192.168.1.5, subnet mask 255.255.255.0, default gateway 0.0.0.0.
•
The FC6A Series MicroSmart IP address, subnet mask, and default gateway can be changed using the HMI module. For details, see Chapter
7 "HMI Function" in the "FC6A Series MicroSmart All-in-One Type User’s Manual".
DNS Settings
The specification method for the DNS server addresses can be selected as the following three types.
Notes:
•
When an IP address cannot be obtained from the preferred DNS server, the alternate DNS server is accessed.
•
The DNS server addresses can be changed using the HMI module. For details, see Chapter 7 "HMI Function" in the "FC6A Series MicroSmart
All-in-One Type User’s Manual".
Specification Method
Description
Obtain an IP Address
Automatically (DHCP)
The FC6A Series MicroSmart will automatically acquire the IP address, subnet mask, and default gateway from
the DHCP server when the user program download has finished and when the FC6A Series MicroSmart power
is turned on. However, a DHCP server must be present on the network where the FC6A Series MicroSmart is
located.
Use Special Data Register
to Configure the
IP Address
Specify the IP address, subnet mask, and default gateway in special data registers D8304 to D8315. These
values are set on the FC6A Series MicroSmart when the FC6A Series MicroSmart power is turned on and when
special internal relay M8190 (CPU module network settings changed trigger) is turned on.
Use the Following
IP Address
Specify a fixed IP address, subnet mask, and default gateway. The values specified here are reflected in the
FC6A Series MicroSmart when the user program download has finished.
Specification Method
Description
Obtain DNS Server
Address Automatically
(DHCP)
The FC6A Series MicroSmart will automatically acquire the DNS server addresses from the DHCP server when
the user program download has finished and when the FC6A Series MicroSmart power is turned on. However,
a DHCP server must be present on the network where the FC6A Series MicroSmart is located.
Use Special Data Registers
to Configure the DNS
Server Addresses
Specify the preferred DNS server address and the alternate DNS server address in special data registers
D8316 to D8323. These values are set on the FC6A Series MicroSmart when the FC6A Series MicroSmart
power is turned on and when special internal relay M8190 (CPU module network settings changed trigger) is
turned on.
Use the Following DNS
Server Addresses
Specify a fixed preferred DNS server address and alternate DNS server address. The values specified here are
reflected in the FC6A Series MicroSmart when the user program download has finished.
