DNP() Sets the CR1000 as a DNP slave (outstation/server) with an address and DNP3‐ dedicated COM port. Normally resides between BeginProg and Scan(), so it is executed only once. Example at CRBasic example Implementation of DNP3 (p. 366), line 20. Syntax DNP(ComPort, BaudRate, DNPSlaveAddr) DNPVariable() Associates a particular variable array with a DNP object group. When the master polls the CR1000, it returns all the variables specified along with their specific groups. Also used to set up event data, which is sent to the master whenever the value in the variable changes. Example at CRBasic example Implementation of DNP3 (p. 366), line 24. Syntax DNPVariable(Source, Swath, DNPObject, DNPVariation, DNPClass, DNPFlag, DNPEvent, DNPNumEvents) DNPUpdate() Determines when DNP slave (outstation/server) will update its arrays of DNP elements. Specifies the address of the DNP master to which are sent unsolicited responses (event data). Must be included once within a Scan() / NextScan for the DNP slave to update its arrays. Typically placed in a program after the elements in the array are updated. The CR1000 will respond to any DNP master regardless of its address. 365
