The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The warehouse stacker example is one of these machines. Pallets are loaded and unloaded into the stacker machine. A maximum of 30 pallets can be stored. The stacker will work as a FIFO (First In First Out) device. This means that the pallets are stored in a sequence and retrieved in a sequence.
The Click PLC will be used to program this virtual 3D stacker machine. Indirect addressing (pointers) will be used to track the positions on the stacker to store and retrieve the pallets. Using the Click Plus PLC, we will connect to the warehouse stacking machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this FIFO is programmed. Let’s get started.
Using the Click Plus PLC, we will connect the simulator to the gantry loader machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this is programmed. The logical sequence step will include a flow chart and a sequence of operations. The sequence of operations will be done using indirect addressing in the Click PLC. Let’s get started.
