Failed to insert library codesys

Hi Amar,

Thank you for the response.

We have setup the modbus master and slave with the tutorial on revpiCodesyslibHelp.
When we run the programm the slave has an error that the bus is not running (error no response time).

we don't know exactly what is going wrong we have followd the tutorial and implent it in our programm.

In the datasheet we can find a modbus register map but we don't know how to implement it in codesys?

Can you help us with this how we can run the slave correct?
There is no motor connected to the frequency generator.

Best regards

Hi,
You can first try to set up the Modbus example in help file.
Modbus register map for the Drive can then be set up according to the one in example.

Further refer to Codesys Modbus documentation
https://help.codesys.com/webapp/_mod_f_ ... n=3.5.14.0

Hi Amar,

It is a little bit late but we have followed the tutorial.
We have also a codesys package from the developer of the frequency generator and now everything is working fine.

so I would thank you for the great support!

Best regards,

Jeroen
