1 INTRODUCTION
This application provides information regarding the access and use of the Webpage of the PLC500. To that
end, first it is necessary to establish communication between the PLC500 and the Computer. To conduct this
communication, the correct settings of the network and devices involved is essential. Please follow the steps
below:
1.1 STEP 1: CONNECTING VIA ETHERNET OR USB
The PLC500 can be connected to the Computer through Ethernet ports (ETH1 and ETH2) or mini USB port
(USB2). Figure 1.1 shows the PLC500 and the three possible connections to the Computer.
Figure 1.1: Connections from the PLC500 to the Computer: ETH1, ETH2 or USB2
Connect the PLC500 to the computer using one of the Ethernet ports or the USB2 port. For more details on
these connections, refer to the specific documentation for each one.
1.2 STEP 2: SETTING UP THE COMPUTER
The Computer must be set with a static IP within the same network used by the PLC500 connection. The default
IP addresses for these communication ports are shown in Table 1.1.
Connection Endereço de IP padrão
ETH1 192.168.1.10
ETH2 192.168.2.10
USB2 192.168.234.234
Table 1.1: Default IP addresses
✓NOTE!
The IP addresses of the ETH1 and ETH2 ports can be changed via the Codesys Development
System or in the Settings menu from the PLC500 Web Page. Therefore, the IP to access the
Web Page may be different from the default values. USB2 IP is fixed and cannot be changed.
Go to Network and Internet Settings and choose the desired interface.
Open the connection Properties and double-click on IP Protocol Version 4 (TCP/IPv4).
Select Use the following IP address. Set the Computer IP address to 192.168.1.X (ETH1), 192.168.2.X
(ETH2), or 192.168.234.Y (USB2), where X is any integer value from 1 to 255, except 10, and Y is any integer
value from 1 to 255, except 234. Leave the Subnet Mask at its default value (255.255.255.0).
Thus, the PLC500 will be ready to be accessed through the Web Page. Figure 1.2 shows the screens for the
Computer network settings.
