Listen carefully: LIR is a system command and it has no substitute in any other PLC types than S5.
You must find out what this function block is supposed to do (it is probably some data moving) and reprogram it in a conveniant RSLogix way.

If you post the FB and the program where it is called, we might be able to lead you in the right direction.

BEB -> you can jump to the end of the program instead.
It is a 'Return to calling block' - command.

:L KHE400 // Loading a start addres for a system area. I don't have a manual here, but it it is probably the start address of the DB index, so this might well be DB0.

:+F // Adding contents of accu 2 to find the start address of the wanted DB number.

:LIR 0 // Loading the address to ACCU 1
:T MW240 // And save it here.


If you had posted more of the code before and after these lines, it would be simpler to analyze.

For beb instruction i used jmp to label at the last of program but it dosn't accept it. Maybe i have to add a nop instruction in the same line !!!

Does the rung you want to jump to have a symbol in it like this?

      ? 
  --[LBL]---

JMP instructions go to LBL instructions only. Also, make sure the LBL instruction is the first instruction on its rung.
