Configuration of the serial interface parameters of the Smart_DP:
Picture 4 – Configuration tool (configuration of the serial interface)
Speed: Baudrate of the RS-232 interface.
Bits: Defines the length of a data word.
Stop bits: Number of stop bits.
Parity: Parity of the serial interface.Use settings: When this option is activated these settings
are used for the configuration of the serial interface (when Smart_DP is started). Otherwise,
the settings sent by the Profibus master during network startup (project data) are used.
Read: Reading the EEPROM stored values.
Write: Writes the actual values to the EEPROM of the Smart_DP module – the settings are not
active before the next reboot of the Smart_DP module.
Note: If the 'Use settings' flag is not activated, the defined values are written to the EEPROM
too, but they are not used after the next reboot. The settings sent by the Profibus master
during network startup (project data) are used.
Important note:
The RS232 interface should always be set to the following parameter settings for
Smart_DP for Radio Modem Series: 19200 baud, 8 data bits, no parity and 1 stop bit.
Only these parameters guarantee a correct functionality with the radio modem.
