Page Comparison

This page shows a few examples of how the KUNBUS Gateways can be used. These are the following:

• Modular Gateway RevPi Gate PROFINET IRT - DeviceModular Gateway

• RevPi Gate EtherCAT Modular Gateway Ethernet- Slave

• RevPi Gate EtherNet/IP - Adapter

• RevPi Gate PROFIBUS - Slave

Connect two PLC together with two KUNBUS Gateways and a Revolution Pi main Module

You can use two gateways in conjunction with a Revolution Pi Core to connect two PLCs.

The advantage of this configuration is:

• The Revolution Pi can analyseanalyze, process and edit the data before forward forwarding it - see RevolutionPi Revolution Pi Gateway Tutorial

• The PLCs can have different protocols

...

• Connectivity

• Retrofit

• IOT

• HMI

Memory Structure

In contrast to the connection as shown in the link, the gateway buffers are handled differently. Here, the buffers are not mirrored by default. You can explicitly access both memory areas of the respective GW.

Simple example.

Connect Two PLC with different protocols.

You can use two KUNBUS gateways wihout without a RevPi Module module to connect two devices (PLC) to support different industrial networks.

Use cases

• Connectivity

• Convert Protocol A to B, or A to A (Both GW do not necessarily have to be different. They can both support the same protocol.)

Memory Structure

each gateway has its own memory. This may vary depending on the gateway. If two gateways are plugged together, the buffer on both sides is automatically configured to have the same size as the gateway with the smallest memory.

The memory on both Modular Gateway Modules is mirrored for each action so that it is not necessary to decide which GW to write to. This means that when a cell is written to, it will be done on both sides.

Control a Revolution Pi IO-Modules from an external device
