store data and parameters in registers. An overview of the Modbus registers of ROTAMASS can be found in

For configuration the ROTAMASS MODBUS communication tool is available from Yokogawa which can
address parameters of ROTAMASS which are mapped onto MODBUS. The tool can be found on the DVD
which is attached to each device. It is running under all recent PC- system and supports all communication
settings of ROTAMASS. To connect to ROTAMASS the user needs a RS232 to RS485 or USB to RS485
converter.
