Page 14: Configuration
Configuration Software AD-Studio via the configuration interface. 6.1 Operating modes The AD-MM 400 can be either a Modbus master (default setting) or a Modbus slave. The operating mode can be changed under ’Device functions’ in the Configuration Software AD-Studio . - Page 15 2. The Modbus data tables of the connected slaves must be known. 3. Set the desired slave address on all slaves. 4. Make sure that all slaves and the AD-MM 400 use the same baud rate and parity. When using devices of the Adamczewski elektronische Messtechnik GmbH , you do not have to worry about it because all devices use the same settings (19200 baud, 8 data bits, even parity, 1 stop bit).

As a master, the AD-MM 400 automatically fetches the value from a holding register of the slave. In the slave mode, the values transferred by the master are displayed here. unit The physical unit of the value is displayed in this area. - Page 23 Master/Slave mode can be used to determine whether the AD-MM 400 is acting as master or slave on Modbus. With ’RS-485 slave address’, the slave address of the AD-MM 400 can be determined in slave mode. In the master mode, this parameter has no meaning.
