S7 in Enture

S7comm is the native Siemens protocol for S7-series PLCs (S7-300, S7-400, S7-1200, S7-1500). The Enture S7 connector communicates directly with the PLC over Siemens Industrial Ethernet (ISO-TCP, port 102) without requiring OPC UA to be enabled on the PLC.

How Enture uses S7

  • An S7 Device represents a single PLC, identified by its IP address, rack, and slot.
  • S7 Parameters map individual memory locations (data block, byte offset, and optional bit offset) on the PLC to trackable data points in Enture.

Once configured, the Enture edge device connected to your facility reads the mapped memory locations continuously and streams the values to the platform.

Note

This section covers connecting a general-purpose Siemens PLC as a Digital Twin device. If you are configuring a Siemens CNC machine for machine monitoring (OEE, live dashboard, alarms), use the CNC-specific workflow instead — see CNC Machines → Siemens S7 Setup.

Typical setup workflow

  1. Add an S7 Device — assign it to a workspace and set its IP address, rack, and slot — see Adding an S7 Device.
  2. Add S7 Parameters — for each memory location you want to monitor, add a parameter with its data block, offset, and value type — see Adding S7 Parameters.

Data flows automatically once the edge device picks up the configuration (within approximately 30 seconds).
