Procedure - Manual - SIMATIC S7 Connector - Industrial Edge - Industrial Edge App

To configure Optimized S7-Protocol (S7-1200/1500) controller data source, follow these steps:

1. Launch the SIMATIC S7 Connector application.
   The configurator home page is displayed.
2. Click Add Data Source in the upper-left corner.
   The Add dialog box is displayed as follows:
   
3. Select the Optimized S7-Protocol (S7-1200/1500) data source from the Data Source Type drop-down.
   The fields are displayed as follows:
   

4. Complete the following fields:
   

   Field Name	Definition
   Name	Defines the name of the data source. It must be unique.
   PLC Type	Specifies the PLC type.
   IP Address	Defines the IP address of the Optimized S7-Protocol (S7-1200/1500) controller with the desired data points.
   Use Legitimization	When selected, Access password is used to acquire the legitimization on server. Not selecting this option is equivalent to the access level Full Access (no protection).
   Access Password	Defines the access password. This field is enabled when you select Use Legitimization. The available access level which requires access password on the PLC are as follows: No Access (Complete Protection) HMI Access Read Access Use corresponding access level password configured on the PLC in this field.
   EndEntity Certificate	Device Certificate. Optimized S7 connection expects one end-entity certificate on HMI Connection-level configured by an ES. If this information is available, it is used when establishing connections to the PLC configured on the HMI Connection.
   Root Certificate	CA Certificate. CA Certificate are used to build a chain of trust for an end-entity certificate of a PLC. Those certificates are trusted by Optimized S7 connection, because they are provided by an ES (e.g. by TIA Portal's WinCC ES); the certificates are most likely generated by TIA Portal.

   * Indicates that all fields are mandatory.

5. Click Add.
   The data source is added and displayed in the Data Source table.

   NOTE

   If Use global security settings for certificate manager checkbox is enabled under Device Properties > Protection and Security > Certificate manager and PLC FW is 2.9, user has to ensure that TLS certificate is configured in the PLC in order to connect with the PLC using Optimized S7 connection.
