9.11.5 Macro instruction argument device (VD)
(1) Definition
Macro instruction argument devices are used with ladders registered as macros.
When a VD setting is designated for a ladder registered as a macro, conversion to
the designated device is performed when the macro instruction is executed.
(2) Designating macro instruction argument devices
Specify the devices transferred from sequence programs to macro registration
ladders as macro instruction argument devices among the devices used in the
ladders registered as macro with GX Developer.
Designate devices that correspond to the macro argument devices used in the macro
registration ladders in ascending order, when using macro instructions in a sequence
program.
