 +This can be the register name, one of the predefined parameters such as "name", "slave_id", "delay", or a role value by passing "roleX" where is X is a number between 0 and the number of roles -1 for that driver.  This will allow you to set a role value which may span two registers (such as a float or unsigned) in one go.  It will take care of sending the appropriate Modbus command to update the value in the device itself.
