modbus RTU with modbus ros driver

[lakshmip001]

Can I use this modbus ros driver to communicate with a communication protocol modbus rtu?

Dear lakshmip001,
as this modbus package is just a wrapper around the library, it the functionality depends on the library. According to the library following protocols are supported:
TCP, UDP, Serial ASCII, Serial RTU, and Serial Binary
However I have not tried yet to use RTU. Maybe you need to do some slight adaptions in the modbus class.

To communicate with this package using modbus tcp, do both robots need ros driver or is it ok if it isnt compatible with ros and still modbus tcp compatible?

[sven-bock]

This package uses the modbus library which implements the modbus TCP standard. The other end just needs to be modbus TCP compatible to work. No ROS required on the other end, otherwise you could directly use ROS message to communicate.

Hi
Can you communicate using modbus tru now?
Can you share to me how to do that?

Thanks
