1 OVERVIEWMELSEC-Q(3) Local station communicationCommunication between the master station and the local station uses two typesof transmission methods: cyclic transmission and transient transmission (seeSection 4.2.3).(a) Cyclic transmissionData communication between the PLC CPUs can be performed in N:Nmode using bit data (remote input RX and remote output RY) and word data(remote registers RWw and RWr).PLC CPUMaster stationLocal stationPLC CPUXAutomatic refreshRemoteinput(RX)Link scanRemoteoutput(RY)Automatic refreshYYAutomatic refreshRemoteoutput(RY)Link scanRemoteinput(RX)Automatic refreshXDAutomatic refreshRemoteregister(RWw)Link scanRemoteregister(RWr)Automatic refreshDDAutomatic refreshRemoteregister(RWr)Link scanRemoteregister(RWw)Automatic refreshD(b) Transient transmissionRead (RIRD) or write (RIWT) operation of the local station buffer memoryand CPU device can be performed at any timing.PLC CPUMaster stationLocal stationPLC CPURIWTRIRDTransienttransmissionareaTransient transmissionTransient transmissionTransient transmissionTransient transmissionTransienttransmissionareaBuffermemoryD1 - 3 1 - 3
1 OVERVIEWMELSEC-Q(4) Intelligent device station communicationCommunication between the master station and the intelligent device stationuses two types of transmission methods: cyclic transmission and transienttransmission (see Section 4.2.4).(a) Cyclic transmissionSignals for handshaking with the intelligent device station (positioning start,positioning complete, etc.) are communicated using the remote input RX andremote output RY. Numeric data (positioning start number, present feedvalue, etc.) is communicated using remote registers RWw and RWr.PLC CPUMaster stationIntelligent device stationServo amplifierXAutomatic refreshRemoteinputRXLink scanRemoteinputRXYAutomatic refreshRemoteoutputRYLink scanRemoteoutputRYDAutomatic refreshRemoteregisterRWwLink scanRemoteregisterRWwDAutomatic refreshRemoteregisterRWrLink scanRemoteregisterRWr(b) Transient transmissionRead (RIRD) or written (RIWT) operation of the intelligent device stationbuffer memory can be performed at any timing.PLC CPUMaster stationIntelligent device stationRIWTTransienttransmissionareaTransient transmissionBuffer memoryRIRDTransient transmission1 - 4 1 - 4
