INGAPT Posts: 3 Rating: (0)	Hi!! I'm trying to translate a s5 program to s7 and i dont know what i must do with the FB's that are protected and with the OB's 21, 22. The FB's that i have mentioned are: FB238 FB239 FB240 FB241 FB242 FB243 FB244 FB245 FB246 FB247 FB248 FB249 FB250 FB251 The problem is that in a segment of the program theres a call to FB241 and there is another one to FB243. I dont know what i have to do , what are the equivalents to these FB's in the S7?? About the OB's, the question is: What are the equivalent OB to the OB21and to the OB22 in S7? Thanks a lot!!!

You mentioned FB241 and FB243. FB241(Code Converter: 16) will be FC82 (COD_16) FB243 (Divider:16) will be FC84 (DIV_16) You can find them in Step7 -> Libraries -> Standard Library -> S5-S7 Converting Blocks. Hope this will help. Best regards, Wizard
