The PLC with Ethernet port integrates the CP243 Ethernet module, but it does not require configuration settings. After configuring the IP address, it can be used directly. It is simpler and more reliable than the CP243 module. Ethernet supports two protocols: S7 Ethernet protocol and Modbus TCP protocol. The upload, download and monitoring of the program can be realized through the network cable, and the download speed is super fast. It can also communicate with the touch screen and directly connect with WINCC. If multiple PLC hosts are connected to a switch, they can also communicate with each other.
IP address view and modification
Connect the PLC with a network cable. The factory default IP address of this machine is 192.168.1.218. The PLC can be directly connected to the computer, or it can be connected to a router or switch, and the PLC can be accessed through the router settings. To access the PLC from the computer, it is required that the computer and the PLC are in the same LAN segment, and the wired network card (note that it is not a wireless network card) IP address is in the network segment 192.168.1.XXX
After filling in the computer’s IP address, test whether the computer and the PLC are physically connected properly. Open the “Command Line Prompt” on the computer, and ping 192.168.1.218. If the PLC returns the data within 1ms, the physical link is normal.

Take the PLC network cable connected to the computer as an example, click Set PG/PC interface in the viewing window and choose according to your computer network card (the picture below is the demo machine network card, the user needs to choose according to your computer network card, the name of your computer network card can be viewed in the “device manager”, if the driver list There is no network card in the computer, this is a S7 software compatibility problem, it is recommended to apply a 64-bit system patch), click Diagnose to test.
OK means that the SR protocol test is successful, but it does not mean that the PLC connection is successful, because even if the PLC is not connected, if the SR protocol is okay, the test will be OK; if it fails, please refer to the “SR Protocol Diagnosis Failure Solution”. Click the communication button on the viewing interface
Click OK, double-click to refresh the list, the PLC model is identified in the host column, indicating that the connection is successful
Be sure to click the searched device, and then click Confirm.

PLC as server, computer (touch screen) as client example
The PLC is the server and the touch screen is the client is the most commonly used connection method. It is also the easiest way to program on the PLC. You only need to write a command. Modbus tcp serves as the server, and the port is 502.

In the above example, only the Socket1 communication port is turned on, segment 1 accesses 192.168.1.205, segment 2 accesses 192.168.1.205, segment 3 accesses 192.168.1.210, segment 4 accesses 192.168.1.213, and the same communication port accesses the unreachable IP Address, this will reduce the efficiency of communication. It is recommended that the same socket only access the same IP address. If you want to access another IP address, open another socket for configuration.
FAQ
Ping fails. Answer: It means that the physical layer is not connected successfully. 1 Check whether the network cable is loose. 2 Check whether the computer IP and PLC’s IP are in the same network segment. 3Whether the computer gateway address, subnet mask and DNS address are filled in completely. 4Turn off the computer’s wireless network card and try. 5 Let the computer and the PLC connect directly with the network cable, and try to remove the intermediate router.
It can be pinged, but the web page cannot be opened. Answer: 1 Try changing the IE browser. 2 https is not allowed in the URL, but http should be used. 3 Try changing to another computer.
The S7 software settings PC/PG interface cannot find the network card driver. Answer: Download the 64-bit patch from the website and try it out.
Two CPU226-ETH devices are hung under the same switch, and one of them is not smooth. Answer: After the PLC leaves the factory, the MAC addresses are all the same. Check if the MAC addresses are the same, and just modify one of them.
The two PLCs can’t communicate directly with the network cable, but they can communicate when they are plugged into the switch. Answer: Try changing the crossover cable.
