Kepware's Siemens S7-200/300/400/1200 Ethernet
device driver works in conjunction with our OPC Server KEPServerEX
, to provide data exchange between OPC Clients and Siemens S7-200, S7-300, S7-400 and S7-1200 PLCs using TCP/IP Ethernet protocol. The S7-200/300/400/1200 Ethernet driver talks directly to the S7 PLC using a standard PC network interface card, no additional software packages or libraries are required. KEPServerEX automatically optimizes your data acquisition based on client demand. Specialized block read and write optimizations automatically increase the speed of many applications by 3-4 times when using CP243, CP343, and CP443 communications processors.
The Siemens Ethernet device driver also supports the netLink adapter cable. The netLink adapter provides a low cost method of accessing either a Siemens S7-300 or S7-400 PLC via Ethernet without the need of the CP343 or CP443 communications card. netLink offers a considerable savings for budget conscience projects.
The Siemens S7-200/300/400/1200 Ethernet OPC Driver is also included in the Manufacturing Suite
