16.1.3 SFC 230 - SEND - Send to page frameThe SEND block initializes a send order to a CP. Normally SEND is called in the cyclicpart of the user application program. Although the insertion of this block into the interruptor the time-alarm program part is possible, the indicator word (ANZW), however, may notbe updated cyclically. This should be taken over by a CONTROL block.The connection initialization with the CP for data transmission and for activating a SENDimpulse is only started, if:n the FB RLO (result of operation) received "1".n the CP released the order.(Bit "order active" in ANZW = 0).During block stand-by, only the indicator word is updated.ParametersName Declaration Type DescriptionSSNR IN INT Interface numberANR IN INT Job numberIND IN INT Mode of addressingQANF IN ANY Pointer to data sourcePAFE OUT BYTE Parameterization errorANZW IN_OUT DWORD Indicator wordIf the CP is able to take over the data directly, the SEND block transfers the requesteddata in one session. If the CP requests only the order parameters or the amount of thedepending data is too large, the CP only gets the sending parameters res. the parameterwith the first data block. The according data res. the assigned serial blocks for this orderare requested from the CP by SEND_ALL to the CPU. For this it is necessary that theblock SEND_ALL is called minimum one time per cycle. The user interface is for all initial-ization types equal, only the transfer time of the data is postponed for minimum one CPUcycle.DescriptionSEND_ALL for data trans-missionVIPA SPEED7 System BlocksFetch/Write Communication > SFC 230 - SEND - Send to page frameHB00 | OPL_SP7 | Operation list | en | 18-30 897
