382 Practical Modern SCADA Protocols: DNP3, 60870.5 and Related Systems These HWT RTUs are: • PDS 550 Compact • PDS 500 Compact • PDS 104 Gateway • PDS 104 RTU • PDS 500 • PDS Compact eNET RTU DNPConfig allows the configuration of the following HWT RTU functions: • RTU ports configuration and function • DNP3 SCADA tables • DNP3 events • DNP3 comms • DNP3 network • Hayes modem • PDS status • Load IEC 61131-3 ISaGRAF application The following panels show the setting up of a PC to perform configuration of an RTU. Note that the configuration is being carried out over the operating communication network using the DNP3 data and file transfer capabilities. The DNP3Config software connects and communicates to an RTU via the PC’s serial Com port. The communication setup between your PC and the network can be edited by selecting the icon below, or selecting View Options from the menu bar. The ‘DNP3 Options’ popup will then be displayed. The Com Port refers to the computer’s serial port that is connected to the PDS. The default Port Baud Rate for connection from a PDS to DNP3Config is 9600 bps. Target DNP3 Address is the software DNP3 address of the RTU you are to communicate with. This address must be known in order to communicate with the RTU. The Application Layer Timeout is the number of seconds DNP3Config will wait for a reply to any command it sends out before signaling a ‘message timed out’ error. This has a default setting of 24 seconds which is usually sufficient for communicating with a local device. If DNP3Config will be talking to a device via a radio or landline network, then the
Applications of DNP3 and SCADA protocols 383 timeout can be increased to allow the PDS to retry communications if the first attempt is unsuccessful due to the network being busy. Local DNP3 Address is set in the Advanced Settings. It is the address of your PC running DNP3Config, and is usually a unique number allocated to each person/PC. RTU type The particular RTU type may be selected to allow RTU specific characteristics to be configured. This popup menu is accessed by the ‘RTU Types’ button on the ‘DNP3 Options’ popup. You will notice all the HWT RTUs that can be configured. To minimize confusion and error, select the required RTU type to be configured. Note that only the tabs for the configuration windows relevant to the selected RTU will be available. The communication ports are setup as required. RTU ports and modes Multi-port RTUs have the ability to interface to different devices. These devices may be radios, PLCs, modems or other HWT RTUs. The Port Function allows the RTU ports to be configured for the following functions: • DNP3 • ISaGRAF • PLC Device • ISaGRAF-User (DNP3 communications I/O e.g. radio, RTU) (Uploading and monitoring of ISaGRAF program) (PLC Port e.g. Modbus, Direct, Koyo) (ISaGRAF serial comms special function)
