5.6.3Direct I/O Operation function

This function is useful when reads an input relay’s state directly during execution of a program and uses in the operation, or write the operation result directly to an output relay. Direct input/output is executed by the ‘IORF’ instruction. If this instruction is used, the input/output image area will be directly updated and applied to the continuing operations.
