TOP Server Siemens S7 Ethernet OPC Driver Details
High-Performance Ethernet Connectivity for S7 Family Controllers
The Siemens S7 Ethernet driver works in conjunction with TOP Server to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and Siemens S7 devices using the TCP/IP Ethernet protocol. TIA Portal import is supported for rapid configuration & integration.
This driver eliminates the need for additional software packages or libraries by supporting direct communication with the S7 PLC using a standard PC network interface card. When using CP243, CP343, and CP443 communications processors, block read and write optimizations work to increase the speed of several applications.
This driver also supports Hilscher NetLink adapters (not included) connected to the controller's serial MPI port.

TIA Portal Exporter Utility
The TIA Portal Exporter Utility enables export of the specific tags users need from Siemens S7-300, S7-400, S7-1200 or S7-1500 controllers programmed with Siemens TIA Portal for automatic generation in their TOP Server project. Provided as a standalone installation, it is compatible with TIA Portal V13 SP1, V13 SP2, V14, V14 SP1, V15, V16, V17, V18, and V19
Capabilities include:
- Select a specific controller within the Siemens TIA Portal project
- Select tags from all tag tables, data blocks, UDTs and function blocks
Search/filter on tag name, address or data type - Import the specific tags required in a TOP Server project
