NL 50-MPI: Ethernet Programming Connector S7-200/300/400

As DIN rail devices that can be installed directly or firmly connected, the NetLink-MPI and netTAP-MPI adapters replace expensive CP communication processors and enable programming, visualization, and control of S7-200®, S7-300® or S7-400® PLCs via Ethernet.

The supplied driver can be integrated as a programming device (PG) in all well-known engineering tools for SIMATIC S7®, such as STEP7® or TIA Portal. The device is configured with the engineering tool or using conventional web browsers via the built-in web server.

The adapters are suitable for programming or modifying S7 PLC control programs and for designing HMI devices with WinCC visualization software. The Ethernet protocol “ISO on TCP” RFC1006 supports the coupling of any SIMATIC ® or third-party visualization station with the PLC. Once integrated into the plant or company network and connected to the Internet, remote maintenance and logging can be performed via a router across network boundaries using the standard TCP/IP protocol.

When organized in a network, direct communication between two or more PLCs via Ethernet can be achieved. PLCs can also be coupled without an Ethernet port. Fully integrated PROFIBUS diagnostics and DPV1 Master Class 2 services allow complete configuration and parameterization of the DP Slave device in STEP7®.

Power is supplied via a 24 V DC connector. The S7 PLC powers the NetLink-MPI connector directly. Since the connector and socket contacts are wired to each other 1 to 1, the NetLink-MPI connector allows trouble-free operation of additional devices on the same MPI/DP bus.

- Connection via any free PROFIBUS/MPI/PPI port
- Cost-effective alternative to the original S7 Ethernet CPs
- Automatic driver integration in any S7 engineering tool
- Easy coupling of two PLCs without an Ethernet interface
- Immediate coupling of S7-compatible HMI devices via Ethernet
- Simplified access via customer-developed applications, e.g. C++, C#
