Hi Everyone,

Just wanted to find out if anyone has done modbus RS485 using the built in function blocks in AS6. I am relatively new when it come to modbus.

Just want to know if there is an example I can refer to or understand the general structure.

Kind regards

Hello,

Just check [the examples](https://help.br-automation.com/#/en/6/libraries/drv_mbus/samples/samples_drv_mbus.html) of the DRV\_mbus library.

Try also looking for Community topics with the DRV\_mbus keyword. There are plenty of them.
