Macro instruction argument device (VD)

The macro instruction argument device (VD) is used with ladders registered as macros. When a VD
specified, the value is converted to the specified device when the macro instruction is executed. With the macro
instruction argument device, VD0 to VD9 can be used in one macro registration ladder.
Among the devices used in the ladders registered as macros, specify a device used for VD. When using macro
instructions in the program, specify devices that correspond to the macro instruction argument devices used in the
macro registration ladders in ascending order.
