1. This instruction denotes the end of the main program. It has the same function
as that of END instruction when being executed by PLC.
2. CALL must be written after FEND instruction and add SRET instruction in the
end of its subroutine. Interruption program has to be written after FEND
instruction and IRET must be added in the end of the service program.
3. If several FEND instructions are in use, place the subroutine and interruption
service programs between the final FEND and END instruction.
4. After CALL instruction is executed, executing FEND before SRET will result in
errors in the program.
