Alumi Posts: 23 Rating: (0)	Hi Sir: I use SFB52 to read data from my IO device. Below is my code. I put my code in OB1. CALL RDREC , "DB54" ptr_type:=Variant REQ :=TRUE ID :="Tag_8" // %MW102 INDEX :="Tag_9" // %MD 120 MLEN :=4 VALID :="Tag_3" // %M110.0 BUSY :="Tag_4" // %M110.1 ERROR :="Tag_5" // %M110.2 STATUS :="Tag_6" // %MD112 LEN :="Tag_7" // % MW116 RECORD :=P#DB10.DBX0.0 BYTE 4 When I start run my program, the "BUSY output toggles between "true" & "false alternately with the "ERROR" output. The "VALID" output remains "false". The following error codes appear on the "STATUS" output; While the "BUSY" output is "true", STATUS is 16#00700100 or 16#00700200. According to the error list it refers to the data transfer being started or it is already active. While the "ERROR" output is "true", status is 16#DE80_B000. Could anyone help me about this? Thanks for your help! Best regards, Marcus ------------------------------------------------------------------------------------------ Split from PROFINET data record.

Alumi Posts: 23 Rating: (0)	Hi Sir: I really appreciate your reply! I did have a look into the Step7-help of the block, but I still do not know what parameter I should modify. In my case, the ERROR and BUSY bit will toggle between "true" & "false alternately, what I mean is that when BUSY is TRUE, the ERROR is False and STATUS has the value 16#00700100 or 16#00700200. When BUSY is False, the ERROR is true and STATUS has the value 16#DE80_B000. The SFB54's parameter VALID is always false and LEN is always 0. You say that 80B1 means that the module doesn´t know the data record that you want to read out. If the module doesn´t know the data record that you want to read out, what parameter I should modify, ID, INDEX or MLEN, or all three of them are possible reason? Please help me! Thanks very much! Marcus
