Software gateway for conversion between Siemens S7 Protocol and Modbus Slave TCP or RTU, saving data to database. The **Marcom S7.Net to Modbus** software handles protocol conversion between Siemens S7 Protocol and Modbus RTU/TCP, also allowing S7 data to be saved to a database. The software allows, without the purchase of additional hardware, to simply and immediately convert the Modbus protocol, from TCP or RTU version to Siemens S7 protocol and vice versa. The product acts as a gateway and allows communication between devices with communication systems on different physical levels. **It also allows saving S7 data to a database (Access, MsSQL, MySQL, SQlite).** All without the need to purchase hardware, but by using any PC present on site. **Marcom S7.Net to Modbus** communicates with Siemens© PLCs. *S7-200*™, *S7-300*™, *S7-400*™, *S7-1200*™, *S7-1500*™ and *LOGO*™, SINVERT™ inverters over Ethernet! Latest generation software ideal for monitoring Siemens Sinvert™ three-phase solar inverters.. ****Marcom S7.Net to Modbus****offers high performance and great ease of use. - Very high performance: communication over an Ethernet network allows very high data exchange speeds - Simple and immediate configuration: guarantees very high commissioning speed - Extremely convenient: a system of sizes to adapt to any need **Marcom S7.Net to Modbus** 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 typical of Siemens development environments. It is possible to simultaneously access an unlimited number of controllers. For communication with **Marcom S7.Net to Modbus**, it is not necessary to modify the program. Access to the controllers can be done directly via Ethernet. An intelligent algorithm for managing read and write requests allows to optimize data *throughput* extremely efficiently: block reading allows unparalleled data refreshing. Configuration takes place 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 S7.Net to Modbus**. The main features of the software 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 | | Configuration | - Intelligent configurator with automatic address syntax error detection - **Equipped with a very advanced tool for integration with Siemens Step7 development software**: allows the selection of DBs and variables to be automatically imported into the configuration, **DIRECTLY FROM STEP7 PROJECT!** - Possibility to directly import .db files exported from TIA Portal | | Supported operating systems | Windows 7/8/10/11 (32-bit and 64-bit) + .NET Framework 4.6.2. | | Multilingual support | Italian and English with online HELP | MPI-Ethernet gateway available that also allows use with PLCs equipped with only an MPI port. Works transparently on the MPI port using gateways: NL50MPI Hilscher, NETLink PRO from Helmholz, NETLink PRO from Softing. --- Source: https://shop.marcomweb.it/en/software-gateway/s7net-to-modbus MARCOM S.r.l. — a trusted supplier for industrial automation and building automation.
