Claim 2:
3. A system, comprising:
a plurality of trainers comprising first and second trainers,
wherein the first trainer is a programmable logic controller (PLC) trainer comprising:
a set of one of more output terminals configured to provide electrical output signals to control one or more electronic devices on other trainers of the plurality of trainers; and
a PLC configured to generate direct current (DC) output signals based on a user design;

wherein the DC output signals of the PLC are connected to a first output terminal in the set of output terminals of the first trainer;
wherein the second trainer is a motors trainer comprising:
a three-phase motor;
a set of one of more input terminals, wherein the first output terminal in the set of output terminals of the first trainer is connected to a first input terminal in the set of input terminals of the second trainer and
a variable frequency drive (VFD) connected to the three-phase motor;
wherein the VFD is connected to the first input terminal of the second trainer; and
wherein the PLC on the first trainer controls the three-phase motor by providing DC signals through the first output terminal of the first trainer and the first input terminal of the second trainer; and

wherein the PLC on the first trainer controls the three-phase motor by providing DC signals to the three-phase motor through the first output terminal of the first trainer and the first input terminal of the second trainer.
