Hi its me with the S5 to S7 project again..

Any one who knows what FB in S7 that matches the FBs in S5 ???
FB 239
FB 238
FB 241
FB 241
FB 242
FB 243
FB 249,
FB 247,
FB 246,
FB 248,
FB 250
FB 251
 
OK, lets see if I can help you out here....

FB238 - Compress PLC memory - I'll pass on this one
FB239 - Delete block - SFC 23 DEL_DB maybe
FB241 - Read analogue value from 463 AI module - L PIW will do this
FB242 - Write analogue value to the AI above - T PIW will do this
FB243 - Read analogue value from 466 AI module - L PIW will do this
FB246 - Fetch data - The S7 equivalent might depend on the comms situation (SFC 66 X_RCV?)
FB247 - Monitor job processing - ????? (Sorry!)
FB248 - Delete job - ?????? (Sorry again!)
FB249 - Initialize interface - this won't be needed as it is used to initialize the comms between the CPU and a CP card
FB250 - Read analogue value again (460/465 AI modules) - Same as before
FB251 - Write analogue output - Same as before

I have not come across FB60 and 61, are they custom written blocks?

Hope this helps you out a bit, maybe others can fill in the blanks
