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
