Data Area Functions

The functions of the various data areas are explained below.

IR Area

Work Bit Area

IR area bits are allocated to I/O terminals. They reflect the ON/OFF status of in

put and output signals. Input bits run from IR 00000 to IR 00015. and output bits

run from IR 10000 to IR 10015.

Note Input bits cannot be used in output instructions. Do not use the same output bit in

more than one OUT and/or OUT NOT instruction, or the program will not execute

properly.

Any of the bits between IR 001 and IR 229 and IR 240 to IR 243 not used for

specific functions can be used as work bits.

The work bits can be used freely within the program. They can only be used with

in the program, however, and not for direct external I/O. Work bits are reset (i.e.,

turned OFF) when the ID Controller power supply is turned off or when operation

begins or stops.

The bits in the ranges shown below have specific functions, but can still be used

as work bits when their specific functions are not being used.
