Customer Rating
The Siemens S7 Server Ethernet driver makes TOP Server® look like an S7 controller. S7 PLCs can connect to TOP Server and exchange data, which 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 an HMI system look like it's an S7-PLC memory space for data exchange between Siemens PLCs and non-Siemens clients, or between multiple Siemens PLCs without cross-programming.
This driver acts as a fully simulated Siemens S7-300 controller with up to 256 virtual devices supported - each with a unique rack and slot configuration. 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.
