PROLINK®S7D 7.0x Siemens SIMATIC S7-Protocol Driver User Manual, introduces the use of PROLINK®S7D 7.0x Siemens SIMATIC S7 Driver, including configuration tables, connections, sample configurations, object references, information and error messages, performance considerations, troubleshooting, installation and authorization, program arguments, system requirements, upgrade information, first-time installation checklist and glossary.
The PROLINK S7D 7.0x driver provides a software interface that connects FactoryLink to Siemens SIMATIC S7‑300/400 series PLCs via SIMATIC NET. It works with a standard 3COM Ethernet card for TCP/IP or ISO Ethernet, or a Siemens Profibus adapter for MPI/PROFIBUS connections. The driver uses the PROLINK ECI task to map PLC data blocks to FactoryLink database elements.
The manual covers configuration tables, connection setup, ECI object definition, sample configurations, performance considerations, troubleshooting, installation steps, system requirements and upgrade information. Detailed examples show how to create ECI objects for statistics, read/write, and bi‑directional data exchange, as well as how to handle dataset size limits and priority settings.
| Required Ethernet card | 3COM Ethernet card |
|---|---|
| Profibus adapter | Siemens Profibus adapter |
| Maximum dataset size | 64 kBytes |
| S7‑PDU size limit (MPI) | 212 bytes |
A dataset can be up to 64 kBytes in size.
The transfer size is limited by the S7‑PDU; for MPI the maximum is about 212 bytes.
