What You Need
Customer provides:
- TIA Portal project access
- PLC parameter access
- DB block documentation
Physical Connection
- 1
Locate PROFINET port
The S7-1500 has one or two PROFINET/Ethernet ports (X1, X2) on the CPU module front. Use the port configured for OPC UA or PUT/GET access.
- 2
Connect Ethernet cable
Cat6 from the PLC PROFINET port to the Flowstate edge node. If the PLC is on a separate network, connect through a managed switch.
- 3
Set PLC IP
In TIA Portal: Device Configuration > PROFINET Interface > Ethernet Addresses. Set a static IP in the 10.0.100.x range. Download to PLC.
Machine Configuration
- 1
Enable PUT/GET access
In TIA Portal: PLC Properties > Protection & Security > Connection Mechanisms > check 'Permit access with PUT/GET communication from remote partner'. Download to PLC.
PUT/GET is required for S7comm protocol access. For OPC UA (recommended), this step is not needed.
- 2
Enable OPC UA server
In TIA Portal: PLC Properties > OPC UA > check 'Activate OPC UA Server'. Set the server port (default 4840). Configure security policy (None for testing, Sign+Encrypt for production).
- 3
Expose DB blocks
For each Data Block to expose via OPC UA: DB Properties > Attributes > check 'Accessible from HMI/OPC UA'. Uncheck 'Optimized block access' if using S7comm. Download to PLC.
Verification
- 1
Browse OPC UA namespace
From the edge node, connect to opc.tcp://<plc-ip>:4840 using UaExpert. Browse to ServerInterfaces > project > DB blocks. Verify tag values match TIA Portal monitoring.
- 2
Dashboard check
PLC data blocks appear in Flowstate with live tag values, correct data types, and update rates matching the OPC UA publishing interval.
