32、protocol .38 Table 24 Information capture the feedback values; synchronise different cycle times and fine interpolators in the PDSs. CP16/1 and CP16/2 shall provide for the cyclic transmission of following telegrams, in that order, as can been shown in Figure 3: 1) The master shall send a synchronis

33、ation telegram that is called MST to all slaves. 2) Each slave shall send its data telegram that is called AT back to the master. 3) The master shall send its master data telegram that is called MDT to all slaves. During network initialisation, the master shall transmit to each slave all parameters

34、that determine the time slot and the data content of these telegrams. In that way each slave shall be able to transmit its AT and to read its part of the MDT without interfering with the others slaves. The communication cycle time shall be selected among the following values: BS EN 61800-7-304:2008

35、20 62,5 s, 125 s, and then 250 s to 65 ms in 250 s increments. 5.11.5 defines 3 granularities. 5.4.2 Handling of command and feedback values The MST shall not only control the access to the network, but also assist in orienting the processing within the PDSs. Designs shall be possible in which the P

36、DSs provide feedback values for the control unit. These values shall be captured in all affected PDSs simultaneously. The capture point indicated by t4referenced to the end of the MST shall be stored in the PDSs as an IDN. The PDSs shall already have a default time interval t5stored as an IDN. This

37、time interval shall indicate the minimum amount of time needed between the capture point t4and the end of the next MST, to allow the PDS to process the captured feedback value for the following AT. t3shall be defined as another parameter. This parameter shall indicate after which time interval, coun

38、ting from the end of the MST, the PDS is allowed to access the new command values transmitted in the MDT. The master stores t3as an IDN in the PDSs. In order to determine t3, the parameter tMTSG(command value proceeding time) shall be stored in the PDSs as an IDN. This parameter shall describe the m

39、inimum time required by the slave to process the new command value(s) for the PDS(s) after the MDT. Figure 3 illustrates these time intervals. Figure 3 Validity of command values and feedback acquisition time in the PDSs Synchronisation of the control loops in the PDSs The feedback values shall be c

40、aptured in time t4in the PDS, and the control loops (cycle time tRcyc) shall be synchronised in the PDS at that time (see Figure 3 and Figure 4). The PDSs need a certain time to activate a newly received command value in the control loop. The command values available at time t3shall be activated in

41、the control loop to the next time t4. If the time between t3and t4is too small, then the command values shall only be activated in the next cycle at time t4. If a PDS is programmed to detect that times t3and t4are in a critical range, it is recommended that the PDS generates a diagnostic message. Th

42、e PDSs manufacturers shall document the dependencies of time t3and t4and the diagnostic message in the PDSs manual. The cycle time within the control unit and the PDSs shall be as specified below: a) The cycle time during which the control unit shall provide new command values for the PDSs shall be

43、called tNcyc. The operating cycle inside of the control unit shall be an integer multiple of the communication cycle time. If the operating cycle time is n times longer than the communication cycle time, the same calculated values shall be transmitted n times in consecutive telegrams: MSTAT MST 1.1

(n is an integer that is not related to the abbreviations) b) Micro-processor controlled PDS shall have operating algorithms that are oriented to the data transmission. The cycle

45、 time during which the PDS shall perform its control algorithm shall be called tRcyc. It shall be an integer divider of the communication cycle time, and shall be in phase with the synchronisation telegram. If the PDS cycle time is z times shorter than the communication cycle time, intermediate valu

46、es for command values shall be interpolated inside the PDS: z tRcyc= tScyc, z = 1, 2. (z is an integer that is not related to the abbreviations) Figure 4 shows graphically how tNcyc and tRcyc relate to tScyc. tNcyc tScyc tRcyctNcycTimer: MastermodeTimer: SlavemodetRcyctScycFigure 4 Synchronisation o

At the same time, the last received position command value shall be provided to the fine interpolator (see Figure 5). Th

48、e fine interpolator shall calculate the differences in the position command values (Pos) for all steps (position control cycles). The differences in the position command values shall be calculated with: the ratio of the NC-cycle time and the PDS cycle time, the position command values, (optionally)
