Ethernet upgrade for S7-PLCs with MPI/DP/PPI port
As directly mountable or as rmly attachable DIN rail mountable device the adaptors netLINK- and netTAP-MPI are replacing expensive CP communications processors and allow the programming, visualization and control of S7-200®, S7-300® or S7-400® PLCs over Ethernet.

The provided driver integrates into all well-known SIMATIC S7® engineering tools like STEP7® or TIA portal as PG/PC programming interface. The device is setup within the engineering tool or with conventional web browsers over the integrated web con guration pages.

The adaptors are suitable to program or change S7-PLC control programs and may serve to engineer HMI devices with the visualization software WinCC. By supporting the ISO on TCP RFC1006 Ethernet protocol any third party or SIMATIC® visualization stations can be coupled to the PLC. Once integrated into the ofce or plant network and connected to the internet also remote maintenance and logging over a router is possible since plain TCP/IP protocol access mechanisms are used.

Organized in a network direct communication between two or several PLCs over Ethernet can be realized. Even a coupling of PLCs with no own Ethernet port is possible using two adapters in conjunction. Featuring full PROFIBUS diagnostics and Master Class 2 DPV1 services enables unrestricted DP Slave device conguration and parameterization in STEP7®.

Power is supplied by a 24 V DC. If supported by the S7 PLC the netLINK-MPI adaptor may be powered over the DSUB9 connector alternatively and its extra feed-through DSUB9 connector allows the connection of further devices to the same MPI/DP network.

Turning any PROFIBUS slave into PROFINET device
netLINK PROXY integrates a PROFIBUS-DP slave into any superordinate PROFINET network. As connector the device is plugged directly onto the PROFIBUS-DP interface of the DP-Slave and connects to the PROFINET network via its RJ45 socket.

On PROFINET side netLINK behaves like an ordinary IO device. The DP-Slaves process data are mapped in accordance with the present PI-organisations guideline into the PROFINET slot/subslot addressing model. Commissioning is done via the Ethernet port with either a direct connection to the PC or if already installed and during run time via a PROFINET switch. netLINK PROXY is configured with the FDT/DTM based planning, configuration and diagnostic tool SYCON.net.

With few steps netLINK is getting operative. In case there is no slave GSD file available, a scan function is able to identify the slave on PROFIBUS. After the configuration and the I/O process data length is known, SYCON.net converts the parameters automatically into a standardized GSDML file. This file imports to any PROFINET controller configuration utility and gets netLINK into operation effortless. The netLINK Proxy is supplied by 24 V. During mounting the voltage can be tapped comfortably from the DP-Slave and be led to the 2-pin COMBICON connector. The short distance on PROFIBUS makes a terminator unnecessary.

netLINK PROXY a cost-efficient and handy alternative to redevelopments to get existing DP devices integrated straightforward into the PROFINET world.

I/O protocol gateway for basic conversions
netTAP 50 is a protocol converter for simple conversions. netTAP 50 converts 1-port Real-Time Ethernet, fieldbus and serial automation protocols. Slave to slave or slave to master conversions are supported. As a master, netTAP 50 provides full master functionality to one slave device only. This makes it easy to integrate a single field device into any higher-level network.

The design impresses with a cost-optimized, compact hardware implementation being reduced to the elementary requirements of a protocol converter. The converter addresses market segments which set the focus on cost savings. The cost-reduced design combined with its countless conversion possibilities makes netTAP 50 an attractive gateway in terms of price and universality.

netTAP is configured and diagnosed by the universal FDT/DTM technology based configuration tool SYCON.net. LED indicators are visualizing status information for rapid on-site diagnostics. The protocol conversions are preprogrammed and loaded as firmware into the device on demand. Conversions needing the same physical network interface can be managed by a single device variant. So a device can be for example a PROFIBUS slave on one hand or a PROFIBUS master by a simple firmware change on the other.

Maximum Cyclic Process Data

The maximum convertible number of I/O data of a protocol combination is determined by the protocol with the lower amount if I/O Data.
Note: All technical data may be changed without further notice.

Ordering example: PROFIBUS Master to EtherNet/IP Slave = NT 50-DP-EN
* Master license included; supports Master functionality to one slave (Modbus RTU/TCP without limitations)

I/O protocol gateway for demanding conversions
netTAP 100 is the protocol converter for sophisticated conversions and supports 2-port Real-Time Ethernet to serial, Fieldbus to Fieldbus, Real-Time Ethernet to Fieldbus and Real-Time Ethernet to Ethernet automation protocols. It supports slave and master functionality in any combination. Master functionality is unrestricted when licensed.

A memory card slot allows the user to save firmware and configuration data on a removable card. In case of failure all that is necessary to bring the plant back on line within seconds is to move the memory card from the old netTAP 100 onto a spare unit.

Apart from standard protocols, netTAP 100 supports the creation of serial protocols with the Lua-based scripting language netSCRIPT. A full featured development environment is included within the delivery. It allows the comfortable and rapid programming of any proprietary serial protocol as well as the I/O data pre-processing during the conversion into the other field protocol.

I/O protocol gateway for basic conversions

The gateway netTAP 151 transmits IO data bidirectionally between any two industrial Real-Time Ethernet networks. It is the ideal solution for installations with heterogeneous networks or such of the same kind to exchange data across given network boundaries. With more than 25 different combinations of the protocols PROFINET, EtherCAT, EtherNet/IP, POWERLINK, Sercos and Modbus TCP, the device series provides a solution for any conversion.

The integration as simple I/O device into the primary network makes the converter compatible with any common PLC. On the secondary side it works either as I/O device too or controls a subordinate network as a bus master. The length of the I/O data can be scaled to any application and the data in between can be mapped on byte level arbitrarily.

Secure network separation is provided by two Ethernet controllers, each connected to a Dual Ethernet port with integrated switch. That allows realizing star, ring and inline network topologies without further peripherals. Both controllers handle the protocols independent from each other and exchange only the I/O data across a data buffer. An overall data processing time lower than 10 milliseconds is achieved.

The devices can be ordered preloaded with fi rmware and license or unloaded. Unloaded devices minimize the storage costs. Subsequent loading of a firmware configures these devices for any conversion most exible. All devices are commissioned and diagnosed network independent over USB.
