How RevPi Gate PROFIBUS Slave works ?

[JuspB]

Hello,

First of all, let me say that your job is very interesting and amazing.

I was wondering how Profibus slave works. You have to load in your PLC bus configuration the RevPi Gate PROFIBUS slave GSD file and then can you read from the RevPi Core all the data writed from your PLC and vice versa? Let's say that it works like a gateway from the RevPi core and you PLC device? Do you have any documentation about that?

Thanks for your attention and best regards!

Hello JuspB,
we have the RevPi Gate Profibus. You can attach it to your RevPi Core module.
https://revolution.kunbus.de/shop/de/re ... ibus-slave

Therefore your network may look like so
[ Profibus Master Node ID #1 ] - [ RevPi Gate Profibus Node ID #5 ] - [ RevPi Core ]

The RevPi Gate Profibus is a DP-V0 slave which may handle up to 12 MBit/s and 244 Bytes
of data for input and 244 bytes for output. This input and output data is handled as
an unstructured block of bytes.

1) Configure your Profibus Network
i.e. 244 bytes for input and 244 bytes for output using the available modules which are in the GSD file
set the Node ID #5 on the RevPi Gate Profibus device using the two dip switches.

2) Configure the RevPi using PiCtory
i.e. RevPi Gate Profibus LEFT of the RevPi Core
You may give each RevPi Gate Profibus byte a unique name or just work with the defaults i.e. Input_1, Input_2, ...

3) Set the profibus master into data exhange mode and set some output data

4) you can read the data from the profibus master on the RevPi i.e. by using

Code: Select all

piTest -r Input_1
