What can you learn with this automation game?
Start with basic inputs and outputs, then discover latching, AND and OR logic, rising-edge counting, timeouts and sequential control. Each task presents a specific operating condition. Select a rule, test it and use the feedback to understand your choice.
The valve tasks introduce normally closed and normally open valves, tank filling and draining, mutual interlocks, and single-coil and bistable pneumatic valves. Complete the final filling, waiting and draining cycle by choosing the correct sequence.
