216 Practical Modern SCADA Protocols: DNP3, 60870.5 and Related Systems Master Station A RTU B P P 1. A control direction ASDU is issued by RTU D to RTU C. 2. The ASDU is routed by RTU B to RTU C in accordance with the common address. 2 1 ASDU CA = C 0 = D RTU C S RTU D S Figure 8.21 Control command issued from dual-mode RTU Master Station A P 3. An action confirmation ASDU is issued by RTU C in the monitoring direction. This has orginator address D. ASDU CA = C O= D ACTCON RTU B P 3 4 4. The non-zero orginator address D in a monitor direction ASDU is recognized by RTU B which routes the ASDU to RTU D. RTU C S RTU D S Figure 8.22 Activation confirmation ASDU returned to dual-Mode RTU
Fundamentals of IEC 60870-5 217 Master Station A ASDU CA = C O= D RETREM 5 6 RTUB P P 5. Changes in the state arising from the command cause a return of information ASDU. This has originator address zero so it is returned to the master station. 6. The ASTU is directed to the master station as it has the default orginator address = 0. RTU C S RTU D S Figure 8.23 Monitoring information returned to SCADA master 8.6 Information elements As has been shown in the preceding sections on ASDU structure, application data is carried within the ASDU within one or more information objects. Depending on the variable structure flag there may be multiple information objects each containing a defined set of one or more information elements, or there may be just one information object containing a number of identical information elements. In either case, the information element is the fundamental component used to convey information under the protocol. The information elements are used as building blocks in the definition of the set of ASDUs under the protocol. In this section this set of information building blocks is presented. These are referred to in the following section when the set of ASDUs are defined. In the following definitions, these interpretation rules should be noted: • Key descriptions give the logical state for a set bit, i.e. bit = 1 • Blank bit positions are reserved and must be cleared, i.e. bit = 0 • Bit positions have been numbered for consistency within this text and the powers of 2 the positions represent. Note that the IEC documents actually use . This is a matter of definition only and does not change the meaning The set of information elements is listed in Table 8.15. This is followed by representations of each of the data elements, grouped by general type.
