Specify here an area of type pointer, in which the received data are to be copied. Specifytype, start and length.Example:n Data are to be stored in DB5 starting from 0.0 with length 124byte– DataPtr:=P#DB5.DBX0.0 BYTE 124This word gets an entry in case of error.Error code Description0003h DB with telegram buffer does not exist.0004h DB with telegram buffer is too short.7000h Receive buffer is too small - data have been deleted!8000h Pointer setting in EMPF_PUFFER is faulty or does not exist.9001h DB setting in EMPF_PUFFER is faulty or does not exist.9002h Length setting in EMPF_PUFFER is faulty or does not exist.10.1.6 FB 7 - P_RCV_RK - Receive from CP 341Please note that this block can only be used in CPUs from VIPA or inS7-300 CPUs from Siemens!The FB 7 P_RCV_RK transfers data from the CP to a data area of the CPU specified bythe parameter DB_NO, DBB_NO and LEN. For data transfer the FB is to be called eithercyclically or statically by a timer-driven program. Please note that this block calls the FCor SFC 192 CP_S_R internally. These must not be overwritten! The direct call of aninternal block leads to errors in the corresponding instance DB!ParameterParameter Declaration Data type DescriptionEN_R IN BOOL Enables data readR IN BOOL Aborts request - current request is aborted and receiving is blocked.LADDR IN INT Logical basic address of the CP - corresponds to the address of thehardware configuration of the CP.DB_NO IN INT Data block number - number of the receive DB, zero is not allowed.DBB_NO IN INT Data byte number - received data as of data byte 0 ≤ DBB_NO ≤8190L_...
