Relay overview

The function blocks only output a selection of the most common data. These data are described on the respective pages under "Outputs". If more or all data is required, the function blocks FB_MBUS_General, FB_MBUS_General_Ext or FB_MBUS_General_Param from the "General" folder should be used. Note that these function blocks cannot be run on BC and BX systems. If data must be sent to the device (e.g. setting the primary address), the function block FB_MBUS_General_Send can be used.
