PLC Steps – Your Guide to Industrial Automation

This tutorial explains how to create a new WinCC 7.5 project and configure communication with an S7-1200 or S7-1500 PLC.

• Open WinCC 7.5
  • Launch WinCC 7.5 from your Siemens Start menu.
• Create a New Project
  • Once the WinCC Explorer opens, go to File -> New
• Select Project Type
  • A dialog window will appear. Choose Single User Project, unless you specifically need a Multi User Project or a Client Project.
• Enter Project Name
  • Type a name for your new project and confirm.
• Project Interface Opens
  • WinCC Explorer will reload and display the menu structure of the new project.
• Open Tag Management
  • Double-click Tag Management from the project tree.
• Add a Driver
  • When Tag Management expands, double-click it again and select:
  • Add New Driver → SIMATIC S7-1200, S7-1500 Channel (Choose a different driver if you are using another PLC type.)
• Create New Connection
  • A new subfolder named OMS+ will appear.
  • Right-click it and select New Connection.
• Configure the Connection
  • A new connection object will be created.
  • Right-click the connection and choose Connection Parameter.
• Set the PLC IP Address
  • Enter the IP address of the PLC CPU you want to connect to.
• Select the Access Point
  • Choose the correct access point, typically:
    • S7ONLINE (If using MPI or another interface, check the current setting in Set PG/PC Interface.)
• Select Product Family
  • Choose S7-1500 connection (If you use 1500 series)
• Check the Access point. Choose S7ONLINE (STEP7).
• Check Set PG/PC Interface and verify that the Interface assigned is correct.
  • For simulation purpose choose PLCSIM.TCP or Siemens PLCSIM Virtual Ethernet Aapter (TCP/IP single Adapter) or Your Computer’s Network Adapter (if you have physical CPU connected)
