    Leuze devices, such as the BCL 8, BCL 22, etc., directly to the fieldbus. This is accomplished by transmitting the data from the Leuze device via an RS 232 (V.24) interface to the MA 248 where a module converts it into the fieldbus format.

  • Page 17: Operating Modes

    For fast commissioning, the MA 248 offers an additional operating mode, the "Service mode", in addition to the "Standard mode". In this operating mode, the Leuze device can, for example, be configured on the MA 248 and the communication can be tested on the fieldbus. To do this, you need a PC/laptop with a suitable terminal program, as BCL-Config from Leuze or similar.

  • Page 18: Fieldbus Systems

    ATTENTION! For the service PC to function, the RS 232 parameters must be the same as those of the MA. The Leuze standard setting of the interface is 9600bd, 8N1 and STX, data, CR, LF. Fieldbus systems Various product variants of the MA 2xx series are available for connecting to different fieldbus systems such as PROFIBUS DP, PROFINET-IO, DeviceNet and Ethernet.
