Instraction CALL-P+D

When the CALL instruction is active it forces the program to run the subroutine associated with the called pointer. A CALL instruction must be used in conjunction with FEND and SRET instructions. The program jumps to the subroutine pointer (located after an FEND instruction) and processes the contents until an SRET instruction is encountered. This forces the program flow back to the l ine of ladder logic immediately following the original CALL instruction.
