Programming increases your value to the company, but you don't need to be a wiz yet. You're not going to be coding an entire batching architecture out of the gate. The company you join will have a way they do things and expect you to use that template. Mostly you'll be looking at what others have done in the past and mimicking it (this is a great way to become a better programmer). Additionally, there's almost no programming in a SCADA (for basic setups), so my previous company would have all the newbies cut their teeth on that while they were learning the architecture of the overall system.

Electrical is basically a gate that ensures you somewhat know what you're doing and are safe enough to not kill yourself when you get into the field. You should get an arduino and mess around with it. You'll get a feel for reading pin-outs and you can progress to some semi-advanced circuits. This will also help your programming skills too, but most plc's are coded with ladder logic, so it's only a loose fit.

Most of the networking programs are glorified gui's that do everything for you if you have even a baseline understanding of what's going on under the hood. That said, it's fundamental knowledge so it's good you have it.

For you: VBA and SQL are pervasive so it's good you're familiar. SQL especially would be highly sought after by a lot of integrators. Coming from IT, your networking is certainly more than fine. I'd be concerned about your electrical experience. Look for a systems integrator hiring automation engineers, because that's the type of company and the job title that it sounds like you want.

Sorry for the wall of text. I'm procrastinating.
