My company (Automation & controls) is partnered with electricians for all the jobs we bid on. Having electricians that know wiring for specialized bus networks, how to do basic troubleshooting on control circuits and all that is amazing to have.
Alternatively, for those reading this in the tech side, the job is super engaging. I get to work on programming machines the size of my bedroom. I get to travel and see equally interesting locations (Dam spillways, Agricultural facilities inland and at port, underground mines, etc.). The fact that I get to get out of my office a few days a month is a big reason I've stuck with my job for as long as I have (7+ years now)

As long as you understand digital logic well enough you'll be able to grasp the concepts. Having more formal education helps but is one of those fields that isn't strictly necessary unless you're working in a specialized sector. My personal take is that Software is still playing catch-up in this domain to the rest of the world but its coming. Up until the last 5 or 10 years the software was mostly just running the facilities but now integration to the business environments is becoming a bigger and bigger requirements of my clients.
I've mostly become hands off on the PLC/SCADA systems at my company now because the requirement for software utilities to function within the control system for data collection, trending, reporting, etc. has become so so much bigger. I have clients that want to use OCR to track shipping containers throughout their yard, clients who want me to integrate their invoicing systems to the operations so staff can see the scheduled daily loads coming, designing unmanned kiosks for customers to key through when coming to site and a whole lot more things.
The programming languages are all defined in IEC 61131-3, and you can more or less use them interchangeably. You can use structured text for (clunky) text-based programming, ladder logic if you want to feel like an electrician in the 70s, or functional block diagrams if you like flowcharts. They each have pros and cons, and being able to use the different languages (with different paradigms) in a single application is one of the more interesting things about PLC programming. There are probably good textbooks for this, but I don't know of any.
PLC programs execute in a constant loop (scan inputs, execute program, set outputs), so basic programming problems (e.g. delaying execution of some function) often require some re-thinking on PLCs. Having a basic understanding of how a PLC actually executes your code is pretty critical. Again, there are probably textbooks for this, but if you buy a physical PLC, its datasheet might also explain this.
You'll need to connect the PLC to some hardware for it to do anything meaningful, so having a basic knowledge of electronics would be useful. If it's just a hobby, you probably wouldn't need to know any more than you would if you were working with an Arduino.
There aren't that many major PLC vendors, so to get started, you could by an entry-level PLC from one of the big players (e.g. Allen-Bradley Micro800 series). Admittedly, I haven't looked at PLC options in 5+ years so there might be better options these days. Unfortunately, PLCs are pretty pricey, and even a small one will probably set you back a few hundred bucks. There are probably simulators available if you're just curious about PLC programming languages, but I don't have any experience there.
Right now I'm trying to hack my treadmill with an Arduino unit so I can control it with software, and I'm learning a ton. Plus it's not a huge investment.

> Find your way into Industrial Electrical work if you can. You get a strong mix of tech and electrical, moreso than Residential, can't really say the comparison to Commercial work though...
Avoid residential electrical work if you are technology oriented! Yes, yes, home automation and all that, but that pales in comparison with industrial work. Commercial in theory has the same potential, but (at least here in Italy) the jobs are ..hm.. dodgy (very poor project management, tasks scattered across sub-sub-sub-contractors so nobody has really a clue of the global picture ..stuff like that)
The guy who got me my job was a MS CS, my employer sought him out because they needed a guy for internal software projects. I did a hackathon with him and he hired me as his replacement when he moved to the gaming industry.
My degree is Software Systems Engineering, most of my coworkers are Electrical Engineers or some form of Electrical Diploma.
As long as you have a decent foundation in Networking and Digital Logic you'll be perfectly suited to program PLC/SCADA...
Edit: System integrators as sibling says, I second that!
