TOP Server Siemens S7 Server Ethernet OPC Driver Details
High-Performance Unsolicited Connectivity for S7 Family Controllers
The Siemens S7 Server Ethernet driver makes the TOP Server look like an S7 controller. S7 PLCs can then connect to the TOP Server and exchange data, which the TOP Server then makes available to OPC UA, OPC DA, SuiteLink and DDE clients. Very creative solutions can be built using this methodology, such as making your HMI system look like it's an S7-PLC memory space.
This driver acts as a fully simulated Siemens S7-300 controller with up to 256 virtual devices supported. TOP Server eliminates the need for additional software packages or libraries by supporting direct communication with the S7 PLC using a standard PC network interface card
Siemens devices require specialized ladder programming to communicate with this driver as they think they are talking to an S7-300 memory space.
See Appendix: Configuring Connections Using the SIMATIC Manager in the Siemens S7 S Ethernet Help File.
