If it can still help, I ask for some information to the support, this is what they answered me. 


The MODBUS Set Slave ID is used only when UniStream controller is the slave. In this case you can change the slave ID from the HMI.

In order to use that function block, your A parameter is going to be linked to the "SlaveID" tag within the RS485 Modbus Slave struct. The B parameter will be a UINT8 Tag that holds the desired slave ID.


Once finished, the B parameter and status get set to 0.
