Banxico Posts: 15 Rating: (2)	I have a problem for read data from COM15 (Sentron), with SFC 59. I have configured five COM15 in HW config. First COM15: Address DP : 6 y Diagnostic address: 8189, Address Input Start from HW Config: 256 DEC (100 HEX) Second COM15: Address DP : 8 y Diagnostic address: 8188, Address Input Start from HW Config: 300 DEC (12C HEX) Third COM15: Address DP : 10 y Diagnostic address: 8187, Address Input Start from HW Config: 38 DEC (26 HEX) Fourth COM15: Address DP : 16 y Diagnostic address: 8186, Address Input Start from HW Config: 388 DEC (184 HEX) Fifth COM15: Address DP : 18 y Diagnostic address: 8185, Address Input Start from HW Config: 432 DEC (1B0 HEX) I attempt to use SFC 59 to read the DS_94 data (Current metering values (Length 197 Byte, read only) part 1), but only I can read a COM15 with address 100 (HEX). When I want to readCOM15 with address 12C (HEX), 26 (hex), 184 (HEX) and 1B0 (HEX), appears error RET_VAL = 8090 = Specified logical base address invalid: There is no assignment in SDB1/SDB2x or there is no base address. In example LADDR =300 inDEC. W#16#12C in HEX. Example of FC20: CALL SFC 59 //Read data record REQ :=M10.0 IOID :=B#16#54 //Identified for “inputs” LADDR :=W#16#12C //Log. base address //from HW Config RECNUM :=B#16#5E //DS 94 RET_VAL:=MW11 BUSY :=M10.1 RECORD :=P#DB200.DBX 0.0 BYTE 200 //DB200, bytes 0-240 How I can read the data from HW Config 12C (HEX), 26 (hex), 184 (HEX) and 1B0 (HEX)? Because I have error 8059. I attachment several picture from HW Config y FC20 Thanks Attachment HW Config y FC20.zip (881 Downloads)

Banxico Posts: 15 Rating: (2)	Hi Aret, thank you for your reply, SFC13can readdiagnostic data structuredin accordance with EN 50 170 Volumen 2, and I need to read Data Record number for DP-slave. I can read any Data Record number for DP-slave with Address DP : 6, Diagnostic address: 8189, Address Input Start from HW Config: 256 DEC (100 HEX) But I can'treadanyData Record number for DP-slave with HW Config 12C (HEX), 26 (hex), 184 (HEX) and 1B0 (HEX)? Because I have error 8059

chibby0ne Posts: 8 Rating: (0)	Hi Banxico, I think that the problem is in fact the logical adress, see when using mixed modules (e.g: with inputs & outputs adresses) you specify the lower of the two adresses types. Looking at your pictures in the HWConfig you attached: you have 300 (lower INPUT) and 258 (lower OUTPUT) but you are using 300 (12C HEX) when you should be using 258 (102 HEX). Try this and let me know what comes up.

Banxico Posts: 15 Rating: (2)	Thank you chibby0ne for your answer, About my problem, It was resolved when I upgrade S7-300, because Icouldn't readDPV1.

chibby0ne Posts: 8 Rating: (0)	But you had to modify the logical adress too right? Andwhat PLC where you using before?
