Parallel data access

With the excom Ethernet gateway GEN, Turck opens up the world of the process industry for digitization and Industry 4.0. For the first time, all process, diagnostic, status and additional data can be transmitted at sufficient speed via a parallel data channel, without feedback into clouds or other IT systems for analysis and evaluation - a fast and easy way to achieve efficient condition monitoring and improve predictive maintenance. Controls and control systems remain completely unaffected and protected against access. Data transfer to cloud systems is carried out via: MQTT, OPC UA, Turck's encrypted cloud protocol Kolibri or via other open standards. 


Cloud connection - also on premises

In addition to the transmission of time-critical user data to the control system, excom can transmit analysis data to any IT system in the network via parallel data access. However, it is advisable to first analyze data in an edge device and then send only the results to the cloud. The cloud can again be implemented as a "private cloud" without Internet access (on premises) or in the classical way.

Here, Turck offers alternative paths in addition to its own cloud solution with industry-specific data visualization and the encrypted cloud protocol Kolibri for the highest security requirements. Via the Turck cloud hardware, data can also be transferred to one of the large cloud systems via MQTT or OPC UA.

Highest availability thanks to redundancy

The integrated Ethernet switch enables simple line topology construction without external switches. An extension of the line topology to a ring topology is possible at any time using the redundancy protocol. All that is required is that all stations support the MRP (Profinet) DLR (Ethernet/IP) redundancy protocol. Excom also establishes gateway and power supply redundancy, which further increases the system's reliability and supports further redundancy concepts. 

Redundancy concepts 

Different network topologies:

S2 Redundancy

S2 Redundancy: two masters and one gateway

Two masters, one gateway

By Profinet S2 redundancy the specification understands a system consisting of two controllers and one device, here an excom gateway. Here the masters synchronize themselves internally via a backbone bus and both maintain a connection to the participant. Turck also offers its IP67 IO-Link master module TBEN-L-8IOL with S2 redundancy. 

One master, two gateways

No standard was specified for this redundancy concept in the Profinet context. However, this redundancy also reduces the probability of failure. The advantage: It is more cost-effective than other redundancy concepts. Nevertheless, this concept is rarely used because the control system is usually the most critical point in a system and its failure cannot be compensated for by the solution with redundant gateways.

Two masters, two gateways

Excom can also map the highest redundancy with two gateways and two masters. In this setup each gateway communicates with only one master. The two masters act out internally who is the master and who is the backup master. The simlilar Profinet system redundancy is specified with R1. For Ethernet/IP or Modbus TCP no corresponding redundancy standard of comparable type has been defined so far. However, users of these systems can establish such redundancies with excom.

R2 Redundancy

Turck´s own redudancy solution: 2 master and 2 gateways

Flexible network topology

The gateways have an integrated 2-port switch and can therefore be installed in a line structure like classic fieldbuses. Other standard Ethernet topologies such as star, tree and ring structures are also supported.


One gateway, three protocols - Turck's multi-protocol I/O devices recognize the master after start-up and automatically adjust to the respective PROFINET, Modbus TCP or EtherNet/IP protocol. excom Ethernet benefits from this proven standard and can be used right out of the box with all control systems that support EtherNet/IP, PROFINET or Modbus TCP.
