Q-1) As shown in the shop door system automatically with PLC to be controlled. When the start button is pressed, the system will start to operate and when the stop button is pressed, the system will stop working. When someone comes in front of the door, S3 will be detected by the proximity sensor and the door will start to open. The door will be detected by the proximity sensor S1 and the door will remain open for 5 seconds. After 5 seconds, the door will automatically close. In the meantime, if a person is detected by the proximity sensor S3, the door will start to open again. The closing of the door will be detected by the proximity sensor S2. Design the program that will keep the system running. Write PLC ladder diagram and STL commands.

STL:
The Statement List (STL) programming language is one of the three programming languages available in the basic STEP 7 software package. It is a text-based programming language with a structure similar to assembly language or machine code. STL is the native language of S7-300 and S7-400 processors.
The most common PLC programming methods used are:

  • Relay Ladder Logic (RLL)
  • Structured Text (ST)
  • Function Block Diagram (FBD)
  • Sequential Function Charts (SFC)
  • Instruction List (IL) A ladder diagram is the symbolic representation of the control logic used for ladder logic programming of a PLC.   
    STL mainly consists of the following components which are mentioned below:
  • #1) Containers. A container is a collection of objects of a particular type of data structure. …
  • #2) Algorithms. …
  • #3) Iterators. …
  • #1) Sequential Containers. …
  • #2) Associative Containers. …
  • #3) Container Adopters.
    The STL SequenceContainer types are:
  • array represents a static contiguous array.
  • vector represents a dynamic contiguous array.
  • forward_list represents a singly-linked list.
  • list represents a doubly-linked list.
  • deque represents a double-ended queue, where elements can be added to the front or back of the queue.
