Notes for the VS1 Series PLC Module Expansion
The Main Unit of VS1-10M/VS1-14M/VS1-20M/VS1-24M is not equipped with the module expansion slot.
The Main Unit of VS1-28M/VS1-32M is equipped with the module expansion slot, which can reach 64 inputs and 64
outputs (X0~X77, Y0~Y77), 128 points in total.
The module expansion slot of the VS1 series PLC can be equipped with DIO modules, but not allow special module.
The Main Unit of VS1-28M/VS1-32MT-DI occupies the assigned numbers of X0~X17 and Y0~Y17. Therefore, the
first expansion module is started from X20 and Y20.
The Main Unit of VS1-32M occupies the assigned numbers of X0~X27 and Y0~Y17. Therefore, the first expansion
module is started from X30 and Y20.
The VS-8XY module occupies 8 input points and 8 output points.
The VS-28XYR expansion module will occupy 16 input and 16 output points. Besides, it is unable to expand any
module on its right side.
