Quick and convenient access for the entire SIMATIC S7 series: S7-200, S7-300, S7-400, S7-1200, S7-1500 PLCs, and small LOGO via Ethernet network. Marcom OPC Server UA S7.NET is an OPC Server for communicating with Siemens© PLCs. *S7-200*™, *S7-300*™, *S7-400*™, *S7-1200*™, *S7-1500*™ and *LOGO*™, SINVERT™ inverters over Ethernet network! A latest-generation OPC Server ideal for monitoring three-phase solar inverters model *Siemens Sinvert*™.. **Marcom OPC Server UA S7.NET** offers high performance and great ease of use. As a leader in OPC product supply, Marcom is proud to distribute the clearly best product on the market for OPC products for communication with the Siemens world: - Very high performance: communication over an Ethernet network allows for very high data exchange speeds - Simple and immediate configuration: guarantees very high commissioning speed - Extremely convenient: a sizing system to adapt to any need **Marcom OPC Server UA S7.NET** allows fast and comfortable access to process data in S7-200 (via CP-243), S7-300, S7-400, S7-1200, S7-1500 and LOGO controllers, using a single server. Variables are constantly addressed using the STEP7 semantics specific to Siemens development environments. With any client application that is compatible with OPC specifications, all input and output data, data blocks, and markers can be read and written. Simultaneous access to an unlimited number of controllers is possible. For communication with **Marcom OPC Server UA S7.NET**, no program modification is necessary. Access to the controllers can be done directly via Ethernet. An intelligent algorithm for managing read and write requests optimizes data *throughput* extremely efficiently: block reading allows for unparalleled data refresh. Configuration is done through a convenient graphical interface, in manual mode or thanks to a tool for importing symbolic names from STEP7 projects, from Excel files, or from .db files exported directly from TIA Portal. Existing configurations can, for example, be exported to Excel from visualization or process control systems to be conveniently loaded onto **Marcom OPC Server UA S7.NET**. The main features of the OPC Server are: | Connection/Connections | Access to process data of S7-300, S7-400, S7-1200, S7-1500 and LOGO PLCs via Ethernet. **Redundant access for S7-400H systems**. | |---|---| | Supported data types | BOOL, BYTE, WORD, INT, DWORD, DINT, REAL, TIME, TIMER, COUNTER, Array of Bytes, Array of Words, Array of Int, Array of Float/Real | | Dynamic Variable Support | **Yes, management of variable creation/deletion from OPC client with Siemens OPC Server syntax.
