Product Overview

The Siemens S7 Plus Ethernet driver provides Symbolic access to S7-1200 and S7-1500 PLCs through the native S7 Comm Plus protocol. With online automatic tag generation there is no longer a need to manually transfer your tags from your TIA Portal Projects. The Siemens S7 Plus Ethernet driver supports optimized and non-optimized block access as well as symbolic reads and writes of time, elementary and array elements.
