Hi Hazzem
Simply follow the advice that was already given in this thread (all the answers are already there really, only thing left to do is to grab the 944 manual)
By checking the call of the FB and the value that is assigned to the PADR Parameter (which could also be a FW or DW in which case you'll need to finf out the value in it). |

Hello, can you explain to me these instructions from the "BEGIN" and how can i know the value transfered to the PADR because i don't find any indication that shows a transfer of value as you see, there is just loading. COFF :block_fc; // COFF WDHA :int; // WDHA MAFB :block_fc; // MAFB CHAN :int; // CHAN END_VAR VAR_OUTPUT EROR :bool; // EROR RFLM :bool; // RFLM END_VAR VAR_TEMP conv_akku1 :dword; conv_akku2 :dword; conv_stw :word; conv_ret_val :int; END_VAR BEGIN NETWORK AUF #UBDB ; U #RFLM; SPB M001; L #PADR; L W#16#1; OW; L W#16#EEFF; //CALL SFC 20 ( // SRCBLK := P#????? BYTE 1, // RET_VAL := conv_ret_val, // DSTBLK := P#????? BYTE 1 // ); // *** Erreur à la ligne 1505 (FB 208) : CALL SFC 20 a été généré, veuillez compléter la liste des paramètres. *** I will accompany this with the complete program S7 AttachmentPrg SFC.pdf (318 Downloads) |

I'm afraid to say that your problem pales in comparison to the challenge of anyone here trying to help without you making the required info available. For sure, if you were to make the S5 program available OR - bare minimum - info about the call of FB208 from OB1 and the DB that is assigned to FB208 #UBDB Parameter, someone here may be able to help you further. |
