Communicating between the KingView configuration software and S7-200 SMART PLC via Ethernet can be a bit challenging for beginners who are unsure about the configuration and communication process. Let’s go through the steps together.
01 Download Driver
Step 1: (Download the TCP driver file from the official KingView website)
Download link: http://www.kingview.com/down_info.php?id=S7_TCP.dll
Step 2: (Once downloaded, it should look like the image below)
Compressed file
02 Configure TCP Driver File
Step 1: (Extract the TCP driver file)
Step 2: (Double-click to open the kvS7200.ini file with Notepad)
Step 3: (Keep and modify the section within the red box shown in the image below, delete everything else)
Original format:
[192.168.31.51:0]
/SMART
LocalTSAP=0101
RemoteTSAP=0101
TpduTSAP=000A
SourceTSAP=0000
Modified format:
[192.168.0.145:0] (PLC IP address)
/SMART
LocalTSAP=0200
RemoteTSAP=0200
TpduTSAP=000A
SourceTSAP=0009
Here, “192.168.0.145” is the CPU’s IP address. If there are multiple PLCs, list their IP addresses, for example:
[192.168.0.146:0]
[192.168.0.147:0]
Step 4: (After modification, it should look like the image below, and save it)
Step 5: (Start menu bar – KingView – Open Install New Driver)
Step 6: (Click the three dots in the red box and select TCP driver)
Step 7: (Select the extracted and modified TCP driver folder, choose S7_TCP.dll)
Step 8: (Click Install Driver)
03 KingView Connection Configuration
Step 1: (Create a project, enter a name, and click yes)
Step 2: (Click device and select S7-200 TCP driver)
Step 3: (Enter logical name)
Step 4: (Select any serial port or default)
Step 5: (Set the 200 SMART PLC IP address)
Step 6: (Default is fine)
Step 7: (Creation completed)
04 PLC Program Writing
Step 1: (Write a start-stop program)
Step 2: (Download the program to the PLC and monitor)
05 Design Screen
Step 1: (Data dictionary – define variables)
Variable name: Start
Variable type: IO discrete
Connected device: Created driver name
Register: M0.0
Data type: BIT
Read/Write property: Read/Write
Variable name: Indicator light
Variable type: IO discrete
Connected device: Created driver name
Register: Q0.0
Data type: BIT
Read/Write property: Read/Write
Step 2: (Creation completed)
Step 3: (Screen – create a new screen)
Step 4: (Use button to create a button in the screen)
Step 5: (Check discrete input)
Step 6: (Click the question mark to associate the start variable)
Step 7: (Use an ellipse to create an indicator light)
Step 8: (Check discrete input)
Step 9: (Click the question mark to associate the indicator light variable)
06 Demonstration Effect
Step 1: (File – Save All)
Step 2: (Click to switch to View)
Step 3: (Enter running state)
Step 4: (Click the button to communicate)
