How To Connect To S7 200 Via Ethernet

ETH-PPI Ethernet Module-Amsamotion

Ethernet to PPI module

AMX-ETH-PPI is a Siemens s7-200 ethernet module, it allows s7 200 ethernet communication, Ethernet to PPI module = CP243i+wincc direct connection function (ie PC ACCESS is not used). It allows you to connect to the S7-200 with the driver [TCP/IP(auto)] that comes with WinCC. It is simple, convenient, and practical to make the engineering application complex. Reduces communication instability caused by the use of OPC (ie PC ACCESS)! I, Q, M, DB1 (remember to be DB1) in WinCC correspond to I, Q, M, V in s7-200 It is very simple to use and can be used immediately after filling in the IP address. At the same time, the S7-200 programming software MicroWin 4.0 can also work. The s7-200 can be uploaded and downloaded through ETH-PPI, online debugging, and monitoring. The function is quite powerful. Siemens can’t do it at the same time! In addition, Siemens Prodave 6.0 It is not possible to connect to the S7-200, but with the ETH-PPI converter, the S7-300 TCP protocol is completely feasible! This is the best way to solve problems for customers who like programming, especially in data acquisition projects

Siemens S7-200 Ethernet Module used for

  • connect WinCC does not need to use OPC, you can directly connect, and enhance communication stability.
  • You can use Siemens Prodave 6.0 and VB to develop your own S7-200 with upper software.

Features

  • Indicator function description
  • Long light – the module is in search of PLC status
  • Connected to the PLC successfully – the indicator flashes 1 second in 1 second
  • In PPI communication – indicating fast
  • 1-second flash 3 times – PPI communication is abnormal (PPI line is not connected / PLC is not started)
  • 1-second flash 4 times – TCP exception

Web page settings and queries

Using Google Chrome, enter the IP address 192.168.1.15 (Note: the local computer must be set to the same network segment) Open the web page to join the function list, and then enter the login password (Note: The default login password is 123456).

Query system host parameters

Click the system parameter in the menu bar on the left to query the current MAC address and IP information of the host.

Query/Set System PPI Communication Parameters

You can configure the host’s current IP address and subnet by clicking Parameter Configuration in the menu bar on the left.

Mask, gateway;

Information such as the PLC station number of the PP1 communication, the module station number, and the baud rate of the communication selection.

change Password

Click the parameter configuration in the menu bar on the left to modify the login password. After the password is forgotten, you can use the debugging tool to restore the factory settings through the RS232 port of the module.

Automatic synchronization baud rate

Automatically synchronize the baud rate of the device at power-on. After the device is powered on, the baud rate is automatically synchronized. After success, the indicator flashes once every 1 second.

The web page automatically synchronizes the device end baud rate

Using Google Chrome, enter the IP address 192.168.1.15 (Note: This computer must be set

Set to the same network segment) Open the web page to enter the function list, as shown in the figure:

Hardware connection method:

Line style:

That is, a PLC (s7-200 and a host computer (computer), directly use the cross line (RJ45 network cable)

Connected.

Star mode:

That is, one PLC (s7-200) and two upper computers (computers) or multiple PLCs (S7-200) and one upper computer (computer) or multiple PLCs (s7-200) and two upper computers (computers ), an Ethernet switch is required in the middle, and the switch is connected to each device by a direct connection (RJ45 network cable).

Note:

Use a good network cable communication distance of up to 100 meters, too long a distance will add a pair of fiber optic transceivers and fiber optic cable, and the distance can reach up to 4 kilometers, within 200 meters can add a switch in the middle, play a relay role.

PC settings:

Go to the computer’s “network connection”

siemens s7 200 ethernet module

Go to “Local Area Connection Properties” and select “Internet Protocol Version 4 (TCP/IP4)”, and then

Select “Properties” and click “OK”;

Setting IP

  • Select “Use the following IP” and mark the red part;
  • Then set the IP to 192.168.1.XXX (XXX indicates the value set by the user,
  • It is preferably a value between 10 and 254)
  • Finally, set the subnet mask and gateway to the same value as the picture.
  • Click “OK”.

Once MicroWin is set up, you can program the Siemens S7-200 with MicroWin!

WINCC connection settings:

ETH-PPI=CP243i+wincc Direct connection function [ie PC ACCESS is not used]. It enables you to connect to the S7-200 with the WinCC’s driver [TCP/IP(auto)], making it simple, convenient, and practical in engineering applications. Reduced communication instability caused by the use of OPC [PC ACCESS]!

1. Open WinCC and select the driver, see the following figure: WinCC driver TCP/IP – [mouse right] – system parameters – unit – TCP / IP (Auto)
