Now, I try to use SFB52(RDREC) to read record data and use below codes. L W#16#1234 // Record index --> I am not sure since I check my GSDML of my IO device // Because there are couple record index T MW 100 CALL "RDREC", DB52 REQ := M0.5 ID := DW#16#7FA // Diagnostic address of my IO device MLEN := 2 VALID := M110.0 BUSY := M110.1 ERROR := M110.2 STATUS := MD112 LEN := MW116 RECORD := P#DB2.DBX0.0 BYTE 2 When I download program to PLC, the BF LED turns on, but if I remove program and download again, everything works fine. I think the problem is caused by the program, could you give me suggestion? Best regards, Marcus
