Modbus RTU baud setting?

Gday, Trying to setup the PLC and Master to read a slave device. [ AXC F 2152 PLC with AXL SE RS485] I only need to read from the slave and not write. From the Modbus RTU library, I’m using MB_AXL_SE_RS485_Master_4. Where do I setup the baud rate ? Thanks

The baud rate is part of the hardware configuration: [attachment]2021-07-27_8-38-59.jpg[/attachment] Hope this helps! .
