1. STEP 7 - Micro / WIN
Configure the CP243-1 as a server
Open STEP 7 - Micro / WIN and configure the CP243-1 in "Tools> Ethernet-Assistant".
Create a program on the server CPU
Open the PG / PC interface and set it to PC internal (local)
2. Configure the PC station
Open SIMATIC NCM PC Manager or STEP 7 (depending on the installation program), create a new project and insert a PC station.
Insert an OPC server in slot 1.
Insert an IE_CP in slot 2.
Double-click IE_CP and open the properties.
Now type the IP address and subnet mask and confirm with "OK".
3. Establish a connection to the OPC server
Open NETPRO and insert a new connection.
Double-click the new connection, type "unspecified" as the connection partner, "S7 connection" as the connection and confirm with "Apply". .
In the next window "Properties S7 connection", type the partner IP address (CP243-1) and click address details. The company is located in:
Enter the connection resource "10" for the partner and confirm with "OK".
4. Set up the configuration console on the PC station
Go to "Start> Simatic> SIMATIC NET> Settings> Set PC Station" and select this menu.
In the next dialog "Modules" choose Ethernet card.
Select "General" and select "Configured Operation" with "Index 2" in "Operation Mode of Module". Please confirm with "Apply".
Open the Component Configurator and select "Add".
In "Type" and "Index" 1 and "Name", enter OPC-Server and confirm with OK. & amp; amp; lt;>
5. Transfer the configuration
Return to NETPRO and click PC Station
In the menu bar, select "Save and Transfer" and load the configuration with the "Loading the selected station" button.
6. Start OPC Scout
Start OPC Scout via "Start> Simatic> SIMATIC NET> Industrial Ethernet> SOFTNET Industrial Ethernet> OPC Scout".
Double-click OPC.Simatic NET, set a new group name (CP243-1) and confirm with "OK".
Double-click the new group and in "connections> S7> objects", select the appropriate project.
Click New Definition and select Data Type, Address and Number of Values and confirm with OK. The company is located in:
Click the button labeled "->" to select the entry and confirm with "OK". The company is located in:
The connection between the CPU and the OPC server is established.
7. Create a WinCC project and new tags
Open WinCC and create a new project.
By right-clicking the mouse, click Tag Management and select "Add new driver".
In the next window, select "Opc.chn" and confirm with "Open".
Go to Tag Management and select "System Parameter" in "OPC> OPC Groups" by right-clicking the mouse button.
