Creating I/O Model
Import PLC symbol Data
Imported symbols are stored in PLC Studio as symbol table and can be used to naming operations and events.
This enables I/O model to send and receive signals from PLC.

Define Operation & Event
An I/O model is based on finite state machine (FSM) composed of a finite number of states,
operations and events to mimic the working devices in a work cell. Basically, I/O model is designed to simulate
PLC program behavior integrating 3D model of a manufacturing unit.
A state of an I/O model stores the current state of device which is changed according to occurrence of events and
operations which links one state to another.
Generation graphic Model
Define kinematic
Devices requiring kinematics are first converted to links. Every pair of link is connected together by joints.
Joints may be rotational or prismatic. An axis is defined for each joint. In case of rotational joints, the joints revolve
around the axis whereas in case of prismatic joints, the links translate linearly along the axis

Generation graphic Model : Layout Cell
The PLC Studio cell is an environment wherein the devices may be arranged graphically in a workcell.
The devices may or may not have kinematics. The cell is used to verify the feasibility of the arrangement of the devices by simulating
the operations which these devices are intended to perform in the actual workcell.
The user can customize the working environment individually for each device with kinematics with which the system is intended to function.
