VIRTUAL SYSTEM FOR PLC STUDY(INTERACTIVE TRAINING SYSTEM FOR PLC)

VIRTUAL SYSTEM FOR PLC STUDY(INTERACTIVE TRAINING SYSTEM FOR PLC) .
This system must be a didactic tool for the learning of PLC programming. This trainer must show five virtual industrial processes in order permit to the student to learn how to program a PLC. These processes must simulate real situations as
sorting, batching, palletizing, pick & place and automatic storage; the aim must be to program the PLC in order to control all these virtual processes as real systems. The system must be composed of the above mentioned automation processes based on settings that represents industrial realities. This trainer must permit also the faults simulation for sensors and actuators in open or short-circuit.Thanks to this virtual system, it must be possible to interact with the system as it is a real system, add or remove products from the production line in every moment of the simulation, create faults and jamming of the system.
Main features:
SIMATIC S7-300
CPU 312C
Additional module SM 323
18 digital inputs
14 digital outputs
Power supply
PS 307 24VDC/2A
Micro Memory Card 64kByte
USB PC-adapter
for the connection PC/PLC
480 mm. guide
STEP 7 Lite
Simulation area with
micro-switches and terminals
The information shall be  exchanged between the PLC and the virtual system through a data acquisition board provided with 32 I/O isolated channels and USB interface:
16 channels with inlet voltage  logic0: 2V, Max Logic 1: 5V 50 Vdc max
16 canalioutet voltage 5~40Vdc - sink  current 200mA max / channel
Based on the latest PC technology, this trainer shall make  PLC training easy and fun. The result shall correspond to  an immersive simulated environment that allows highly realistic training processes, without any risk of injury to man or damage to machines.
The automation tasks shall be  presented with increasing levels of difficulty, so that users can progress to more advanced exercises as they improve their skill.
This trainer shall reproduce five training processes based on real world industrial scenarios. Each process shall offer standard problems found in PLC programming, presented in order of increasing level of difficulty.
These training processes shall consist in:
SORTING: transport cases from the entry bay to the elevators, sorting them by height
BATCHING: mix three primary colors (red, green and blue) in order to obtain a desired color
PALLETIZER: palletize cases up to three layers
PICK & PLACE: place parts inside boxes through a three axes manipulator
AUTOMATIC WAREHOUSE: transport, store and retrieve boxes from a rack
The system shall be inserted in a didactic panel with a simulation area of 18 micro-switchers and 2 mm terminals for the digital inputs/outputs. The PLC must be supplied with applications in LADDER language for the control of the five simulation processes. The trainer must be supplied with manual in English language.
