Ethernet PLC Parameters

Ethernet

• The Ethernet parameter is used for 802.3 network communication with the PLC.
• The Ethernet PLC parameter contains the following sections:
  • IP Setting
  • DDNS Setting
  • Option
  • Loader Relay Use

IMPORTANT: The subnet mask and gateway must match the network of the computer to communicate with the PLC.

IP Setting

• IP Address:
  • This is PLC's unique address on the network.
    • Default: 100.100.100.100
• Subnet Mask:
  • This is the range of IP addresses within a network.
    • Default: 255.255.0.0
• Gateway:
  • This specifies the address of the network's gateway (router or central device) that provides access to other networks.
    • Default: 100.100.100.1

DDNS Setting

• Dynamic Domain Name System, DDNS, maps a domain name to a dynamic IP address.
• DDNS 1 Address:
  • Primary DDNS server IP address.
    • Default: 0.0.0.0
• DDNS 1 Port:
  • Specifies the port for the primary DDNS server.
    • Default: 20266
    • Range: 0 ~ 65,535
• DDNS 2 Address:
  • Secondary DDNS server IP address.
    • Default: 0.0.0.0
• DDNS 2 Port:
  • Specifies the port for the secondary DDNS server.
    • Default: 20266
    • Range: 0 ~ 65,535
• Site Name:
  • A unique website identifier associated with this device.
    • Maximum 17 characters
• DDNS Retry:
  • Retry interval, in seconds, if the device fails to connect to the DDNS server.
    • Default: 60 seconds
    • Range: 0s ~ 255s

Option

• Use DHCP:
  • If checked, the PLC will use the dynamic host control protocol, DHCP, to assign an IP address.

Loader Relay Use

• Ch1. (RS232C):
  • If checked, channel 1 is enabled for RS-232(C) relay.
• Ch2. (RS485 Relay):
  • If checked, channel 2 is enabled for RS-422/RS-485 relay.

Wiring

• This interface is satisfied with the IEEE802.3 standard for 10BaseT/100BaseTX.
• The cable and allocation pin number of RJ45 as shown below:

RJ45 Connection
RJ45 Connector	RJ45 Jack

Straight-through Cable (Host ↔ Switch)

• The PLC must be connected to an Ethernet switch/hub if using a standard straight-through Ethernet cable.

Cable	Number	Color	Color	Number	Cable
	1	Orange/White	Orange/White	1
	2	Orange	Orange	2

	4	Blue	Blue	4
	5	Blue/White	Blue/White	5
	6	Green	Green	6
	7	Brown/White	Brown/White	7
	8	Brown	Brown	8

Crossover Cable (Host ↔ Host)

• If the PLC is directly connected to another PLC or HMI, a crossover Ethernet cable must be used.
