The Siemens Unsolicited TCP/IP Ethernet Device Driver was designed specifically for use with KEPServerEX OPC Server.
This driver will act as a simulated Siemens PLC. It is intended for simulation of Siemens S7-300. Up to 256 virtual devices are supported. The mode of communications is S7 Messaging on Industrial Ethernet (ISO 8073 Class 0) over TCP/IP as defined in RFC1006. The driver requires no special libraries or hardware. A standard Ethernet card is all that is needed. Devices require specialized ladder programming to communicate with this driver (see Master Device Configuration).
The Siemens S7 Unsolicited Ethernet OPC Driver is also included in the Manufacturing Suite
