The information made availabledepends on the type of Micrologic control unit (S, A) and on the type ofcommunication bus (Digipact or Modbus).Switch-disconnectors may be connected exclusively to the Digipactcommunication bus.Communication busDigipact busThe Digipact bus is the internal bus of the low-voltage switchboard in which theDigipact communicating devices are installed (with Digipact COM, PM150,SC150, UA150, etc.). This bus must be equipped with a DC150 data concentrator(see the Powerlogic System catalogue).AddressesAddressing is carried out by the DC150 data concentrator.Number of devicesThe maximum number of devices that may be connected to the Digipact bus iscalculated in terms of "communication points". These points correspond to theamount of traffic the bus can handle. The total number of points for the variousdevices connected to a single bus must not exceed 100.If the required devices represent more than 100 points, add a second Digipactinternal bus.Communicating device Number of pointsDC150 data concentrator 4Micrologic + Digipact COM 4PM150 4SC150 4UA150 4Length of busThe maximum recommended length for the Digipact internal bus is 200 meters.Bus power sourcePower is supplied by the DC150 data concentrator (24 V).74
