I'm not sure if you are referring to Triangle's product when you say "the PLC" but in general I would think PLCs are used for traffic light control.  They might be sold as "traffic light control units" but essentially they are just PLCs, I'm sure.

Asking what can you do with a PLC is like asking what can you do with an oven.  Sure you can make pizza but there are plenty of other foods you can cook, too.  (You can even dry your socks in them.)  PLCs are very versatile and can be used anywhere you have inputs and outputs you want to work with programmatically.  Essentially their use is only limited to the inventiveness of their users.
