Siemens 200ppi to Ethernet to achieve Ethernet communication and ModbusTCP configuration method through CHNet-S7200PD

Product Introduction

CHNet-S7200 is used for Ethernet data acquisition of Siemens S7-200/SMART S7-200 PLC, which is very convenient for building production management system.

CHNet-S7200 does not occupy the PLC programming port, that is, while the programming software/host computer software monitors and collects PLC data through Ethernet, the touch screen can communicate with the PLC through the extended RS485 port.

CHNet-S7200 supports most SCADA software in the industrial control field, and supports Siemens S7TCP Ethernet protocol and ModbusTCP protocol.

CHNet-S7200PD straight-through type: CHNet's extended DSUB9-pin female port can connect to Siemens and Proface touch screens, multi-master cables, and communication boards;

CHNet-S7200PB bridge type: CHNet's extended DSUB 9-pin female port can be connected to non-Siemens touch screens, such as Kunlun Tongtai, Weilun, Delta, and Buke.

CHNet-S7200 Features:

1. Support multi-master station communication, the expansion port can be connected to the touch screen or other master stations.

2. Parameters of the device can be set and operation diagnosis can be performed through the WEB server or the configuration diagnostic tool NetDevice.

3. Baud rate 9.6Kbps~187.5Kbps adaptive.

4. Directly installed on the PPI communication port of PLC or the communication port of EM277, no external power supply is required.

5. Support Siemens S7 Ethernet communication driver, including MicroWIN, and support WinCC to connect directly to S7-200 via TCP/IP.

6. Users can use high-level programming languages ​​(such as VB, VC, C#, etc.) according to the CHNetS7 protocol to achieve data communication with S7-200, which is convenient for developing production management systems.

7. Provide CHNetS7 OPC server free of charge, support OPC channel SCADA to communicate with PLC in OPC mode.

8. Integrated ModbusTCP server, Modbus data area can be automatically or edited and mapped to S7-200 registers.

9. It can realize S7TCP connection and ModbusTCP communication at the same time, and supports the connection of up to 32 host computers.

Driver Installation

Before installing the programming driver, the computer must first have Siemens MicroWIN software, STEP7 software or TIA Portal software installed. There should be a "Set PG/PC Interface" icon in the control panel, as shown below:

If the computer's operating system is 32-bit, please install the 32-bit programming driver; if the computer's operating system is 64-bit, please install

64-bit programming driver. When installing, please right-click the driver and install it as [Run as Administrator]. After the installation is complete, please restart the computer.

【NetS7PD1801_setup_x86】 is a 32-bit programming driver;

【NetS7PD1802_setup_x64】 is a 64-bit programming driver.

After restarting the computer, enter the control panel and open [Set PG/PC Interface], where you can see the newly added communication interface:

MicroWIN programming and debugging

There are two ways to program and debug the module with MicroWIN: through CHNet programming driver, or through Siemens Ethernet driver.

5.1.1 Driven by CHNet programming

1. Open MicroWIN software and click the [Set PG/PC Interface] icon in the left navigation bar;

1. Select NetS7PD.PPI.1 in [Assign parameters to the interface used] and make sure [Application access point] is Micro/WIN

—>NetS7PD.PPI.1, click the [Properties] button;

2. If you know the IP address of the module, directly enter the IP address in [Module IP address or domain name] and click the [OK] button;

3. If you don't know the IP address of the module, you can click [Find local module], select the module to connect, and click the [Select device] button.

4. Click the [Communication] icon in the left navigation bar

5. Double-click the [Double-click to refresh] icon, select the PLC to be refreshed, and click the [Confirm] button.

Via Siemens Ethernet driver

1. Open MicroWIN software and click the [Set PG/PC Interface] icon in the left navigation bar;

2. Select the computer's network card in [Assign parameters to the interface used] and make sure [Application access point] is Micro/WIN—>Computer

Network card, click the [OK] button;

Note: Please select the computer network card with the suffix TCPIP

3. Click [Communication] in the left navigation bar;

4. Click the icon below to open the IP address browser;

5. Click the [New Address] button, enter the module's IP address in [IP Address], click the [Save] button, and double-click the saved IP address;

6. Double-click the [Double-click to refresh] icon, select the PLC to be refreshed, and click the [Confirm] button.
