The SP7 Toolkit for LabVIEW is a software add-on that you can use to read and write various data types and exchange the data with programmable logic controllers (PLCs) using TCP/IP communication. This add-on is compatible with Siemens SIMATIC S7 PLCs in the S7-200, S7-300, and S7-400 series that include an Ethernet interface and with Siemens SIMATIC S7-1200 and S7-1500 series. Additionally, the add-on can replace open platform communication (OPC) servers and supports cross-platform use, including real-time systems. The SP7 Toolkit for LabVIEW provides a single SP7 run-time license.
