Then we design the logic based on the user requirements and the safe operation.įigure 1: Garage door project components Inputs and Outputs list So what is the next step in our plan to achieve such job? Of course we need to list these inputs and outputs and give them addresses. Moving to the outputs, there are motor up and down directions, open, close, and ajar status indicators lamps. Also, you can see sensors like the two limit switches on the bottom and on the top to prevent overload that might have occurred on the motors. As you can see my friends, there are inputs like open, close, and stop requested by push buttons. Project detailsįigure 1 shows the project’s components, inputs and outputs that are included in controlling the garage door. So today we are going to implement the project including determining the input and output components, design the logic, programming and testing using the simulator. in garage for domestic and public garage, you should found automatic garage gate or door that is controlled by the PLC ladder logic program. project which is mostly exist in our daily life that is electrical door control. Today we are going to practice what we have learnt through the ladder logic tutorial series. Hello my friends! I hope your doing very good.
