Page Comparison

This page shows a few examples of how the KUNBUS Gateways can be used in and in combination with RevolutionPi products.

...

. These are the following:

• RevPi Gate PROFINET IRT - Device

• RevPi Gate EtherCAT - 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 RevolutionPi Revolution Pi Core to connect two PLCs.

The advantage of this configuration is:

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

• The PLCs can have different protocols

...

you You can also do this with the RevolutionPi Revolution Pi Connect +/S. For this, you need a gateway and a can also use a CON module.

Use cases

• 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 without a RevPi module to connect two devices (PLC) that to support different protocolsindustrial networks.

The configuration is shown in the image below:

...

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

You can read or write the inputs/outputs of a Revolution IO-Module via an external device. This can be done with the help of a KUNBUS Gateway module.

A RevolutionPi Revolution Pi Core or Connect is also required for this.

...

This can also be realized with a CON module.

Use cases

• Remote I/O

• IOT

• Retrofit

Additional Information

• on On each PiBridge, we support a maximum of 5 devices. Only one GW can be used per PiBRidge PiBridge side, and the gateway must always be the last component.

• No gateways or IO modules can be used on the ConBridge. There are special CON modules for this.

• The RevolutionPi Revolution Pi Core SE and Connect SE do not have GW functionality. This means that no KUNBUS GW can be connected there.

• There are not only physical gateways. We also support virtual gateways such as Modbus RTU and Modbus TCP. Only these two can be used as Slave or as Master.
