To connect Ignition to a Siemen S7-1500, S7-1200, S7-400, or S7-300 device

  1. Go to the Configure section of the Gateway webpage.
     
  2. Scroll down and select OPC-UA > Devices.
     
  3. On the Devices page, find the orange arrow and click on Create new Device.
     
  4. On the Add Device Step 1: Choose Type page, select Siemens S7-1200, and click Next.

    There are four modules to choose from

    • Siemens S7-1500
      Which connects to Siemens S7-1500 PLCs over Ethernet.
    • Siemens S7-1200 
      Which connects to Siemens S7-1200 PLCs over Ethernet.
    • Siemens S7-300
      Which connects to Siemens S7-300 PLCs over Ethernet.
    • Siemens S7-400
       Which connects to Siemens S7-400 PLCs over Ethernet.
  5. On the New Device page, leave all the default values and type in the following fields:
    Name: S71200
    Hostname: type the IP address, for example 10.20.4.71

  6. You can check the box for Show advanced properties? to see the additional settings, but you can keep all the defaults.

  7. Click Create New Device.
    The Devices page is displayed showing the Siemens device is successfully created and added to Ignition. The Status will show as Disconnected and then Connected.

Unlike other PLCs, but just like Modbus, Siemens devices do not support browsing, therefore you can not browse the tags by going to the OPC Connections > Quick Client in the Configure section of the Gateway. To see and browse the tags, you need to create the tags manually as described in the About Siemens Addressing section.
