Build a Working Packing Machine with Do-More Designer PLC!
Program a Do-More PLC to run a robot palletizer — boxes stacked with skid sheets between layers — using a sequencer and counter over Modbus TCP. No hardware.
⚡ QUICK ANSWER
This project programs a Do-More PLC to run the automatic packing machine in the Machine Simulator Suite — a palletizing cell where robots stack boxes onto a pallet with a skid sheet between each layer, and an autonomous transport robot carries the full pallet away. The Do-More Designer PLC simulator connects to the machine over Modbus TCP (Ethernet), exchanging digital inputs and outputs, so both the controller and the machine run in software with no physical hardware. The heart of the program is a sequencer paired with a counter: the sequencer steps the machine through its cycle in order, and the counter tracks how many boxes have been placed so the program knows when a layer is complete and when to insert a skid sheet. That combination is the simplest, most maintainable way to program a sequence — far easier to follow and troubleshoot than a sprawl of interlocked rungs. The whole build follows the five-step development process: define the task, define the I/O, develop the sequence of operation, write the ladder logic, and test it. The full step-by-step is in the guide below.

❓ FREQUENTLY ASKED
Q: What's the easiest way to program a sequencer in a PLC?
A: Use a sequencer instruction paired with a counter — the sequencer steps through the cycle in order and the counter tracks position or quantity, which is far easier to follow and troubleshoot than a sprawl of interlocked rungs. The full build is in the guide.
Q: How does the robot packing machine work?
A: Robots palletize boxes onto a pallet with a skid sheet placed between each layer, and once the pallet is full an autonomous transport robot unloads it.
Q: How does the Do-More PLC connect to the Machine Simulator?
A: Over Modbus TCP (Ethernet), exchanging digital inputs and outputs — so the Do-More Designer PLC simulator controls the simulated machine with no physical hardware at all.
